Ixodidae

Only one species of tick was found once on Passalidae: Aponomma exinatum Neumann, 1901 was found on Aulacocyclus kaupi MacLeay, 1871 in the Philippines (Corpuz-Raros 2001) (Tables 2, 5 and 14). It is an accidental host (probably misidentified). (Continued)

(i) Amblyomma laticaudae Warburton, 1933 is considered valid in Camicas et al. (1998), Horak et al. (2002) and Barker and Murrell (2008); Guglielmone et al. (2009) do not include it in their list of controversial names, while Kolonin (2009) considers this name a synonym of Amblyomma nitidum Hirst and Hirst, 1910. In fact, Keirans, in Voltzit and Keirans (2002), determined that the types of these taxa are conspecific. Therefore, we agree with Kolonin (2009) that A. laticaudae is an invalid name. (ii) Bothriocroton decorosum (Koch, 1867) is included as a member of Aponomma by Kolonin (2009), but this name is a synonym of B. undatum, as explained in Santos Dias (1993). (iii) Haemaphysalis vietnamensis Hoogstraal and Wilson, 1966 is included as a valid name in Kolonin (2009), but it is a synonym of H. colasbelcouri (Guglielmone et al. 2009). (iv) Haemaphysalis xinjiangensis Teng, 1980 is not included as a valid species in Kolonin (2009). Teng and Jiang (1981) consider this name a synonym of H. danieli, and we accept their decision, since the senior author also described H. xinjiangensis. (v) Hyalomma erythraeum Tonelli-Rondelli, 1932 is included as a valid name in Kolonin (2009), but it was convincingly shown to be a synonym of H. impeltatum by Apanaskevich and Horak (2009). (vi) Rhipicephalus hoogstraali Kolonin, 2009 was described on the Internet, contrary to the rules of the International Code of Zoological Nomenclature (International Commission on Zoological Nomenclature, 2009, Articles 8.6 and 9.8), and is therefore a nomen nudum. 1. Amblyomma albolimbatum Neumann, 1907 2. Amblyomma albopictum Neumann, 1899 3. Amblyomma americanum (Linnaeus, 1758) 4. Amblyomma antillorum Kohls, 1969 5. Amblyomma arcanum Karsch, 1879 (Aponomma) 6. Amblyomma argentinae Neumann, 1905. Guglielmone et al. (2003) stated that the year of description for A. argentinae is 1904, but this is in error because Neumann recognized 1905 as the correct year. Previously, this species was incorrectly named A. testudinis (Guglielmone et al. 2009). 7. Amblyomma astrion Dönitz, 1909 8. Amblyomma aureolatum (Pallas, 1772) 9. Amblyomma auricularium (Conil, 1878) 10. Amblyomma australiense Neumann, 1905. See A. echidnae. 11. Amblyomma babirussae Schulze, 1933 12. Amblyomma beaurepairei Vogelsang and Santos Dias, 1953. This species is close to A. inornatum and A. auricularium but is provisionally considered valid in Guglielmone et al. (2009). However, Kolonin (2009) considers it a synonym of A. auricularium. 13. Amblyomma boeroi Nava, Mangold, Mastropaolo, Venzal, Oscherov and Guglielmone, 2009 14. Amblyomma boulengeri Hirst and Hirst, 1910 15. Amblyomma brasiliense Aragão, 1908 16. Amblyomma breviscutatum Neumann, 1899. Until recently, this species was known as A. cyprium Neumann, 1899 (Guglielmone et al. 2009), a name still considered valid in Kolonin (2009), who does not justify his position. However, Keirans, in Voltzit and Keirans (2002), determined, as had Santos Dias (1956) before him, that the types of A. cyprium and A. breviscutatum are conspecific and that the latter name has page priority. 17. Amblyomma cajennense (Fabricius, 1787). This is the type species of the genus Amblyomma; it was originally named Acarus cajennensis. Beati, L. and Nava, S. (pers. comm.) believe that A. cajennense comprises a complex of sibling species. 18. Amblyomma calabyi Roberts, 1963 19. Amblyomma calcaratum Neumann, 1899 20. Amblyomma chabaudi Rageau, 1964 21. Amblyomma clypeolatum Neumann, 1899 22. Amblyomma coelebs Neumann, 1899 23. Amblyomma cohaerens Dönitz, 1909 24. Amblyomma compressum (Macalister, 1872) 25. Amblyomma cordiferum Neumann, 1899 26. Amblyomma crassipes (Neumann, 1901) (Aponomma). This species is similar to A. fuscolineatum but is provisionally considered valid because little material is available for examination and the types have not been compared (Guglielmone et al. 2009). Kolonin (2009), using the name Aponomma, considers A. crassipes invalid but does not include a comparison of types. 27. Amblyomma crassum Robinson, 1926 28. Amblyomma crenatum Neumann, 1899 29. Amblyomma cruciferum Neumann, 1901 30. Amblyomma darwini Hirst and Hirst, 1910 31. Amblyomma dissimile Koch, 1844. Guglielmone et al. (2009) argue in favor of this name instead of A. bibroni (Gervais, 1842) because of the confused history of the latter taxon. 32. Amblyomma dubitatum Neumann, 1899. Until recently, this species was known as A. cooperi Nuttall and Warburton, 1908 (Guglielmone et al. 2009). 33. Amblyomma eburneum Gerstäcker, 1873 34. Amblyomma echidnae Roberts, 1953. This species is very similar to A. australiense, but Guglielmone et al. (2009) consider A. echidnae provisionally valid until its status can be clarified. Kolonin (2009) does not include this species in his list of the Ixodidae of the world. 35. Amblyomma elaphense (Price, 1959) (Aponomma). See A. sphenodonti. 36. Amblyomma exornatum Koch, 1844 (Aponomma) 37. Amblyomma extraoculatum Neumann, 1899. See A. romitii. 38. Amblyomma falsomarmoreum Tonelli-Rondelli, 1935 39. Amblyomma fimbriatum Koch, 1844 (Aponomma) 40. Amblyomma flavomaculatum (Lucas, 1846) (Aponomma). See A. inopinatum. 41. Amblyomma fulvum Neumann, 1899 42. Amblyomma fuscolineatum (Lucas, 1847) (Aponomma). See A. crassipes and A. varanense. 43. Amblyomma fuscum Neumann, 1907. A valid taxon ignored in some lists of ticks (Guglielmone et al. 2009). 44. Amblyomma geayi Neumann, 1899. Guglielmone et al. (2009) discuss the lack of agreement concerning this name, because some authors regard A. geayi as a synonym of A. perpunctatum (Packard, 1869). However, the description of the latter taxon is inadequate, and we therefore consider the name A. geayi valid, pending type comparison. 45. Amblyomma gemma Dönitz, 1909 46. Amblyomma geochelone Durden, Keirans and Smith, 2002 47. Amblyomma geoemydae (Cantor, 1847) 48. Amblyomma gervaisi (Lucas, 1847) (Aponomma). This is the type species of the genus Aponomma; it was originally named Ixodes gervaisii. 49. Amblyomma glauerti Keirans, King and Sharrad, 1994 50. Amblyomma goeldii Neumann, 1899 51. Amblyomma hainanense Teng, 1981. Kolonin (2009) considers A. hainanense a synonym of A. helvolum, but no comparison of types has been attempted. Therefore, we treat A. hainanense as tentatively valid. 52. Amblyomma hebraeum Koch, 1844 53. Amblyomma helvolum Koch, 1844 54. Amblyomma hirtum Neumann, 1906 55. Amblyomma humerale Koch, 1844 56. Amblyomma imitator Kohls, 1958 57. Amblyomma incisum Neumann, 1906. See A. latepunctatum. 58. Amblyomma inopinatum (Santos Dias, 1989) (Aponomma). This species is not included in Kolonin (2009), who appears to consider it a synonym of A. flavomaculatum and places it in the genus Aponomma. 59. Amblyomma inornatum (Banks, 1909) 60. Amblyomma integrum Karsch, 1879 61. Amblyomma javanense (Supino, 1897) 62. Amblyomma komodoense (Oudemans, 1928) (Aponomma) 63. Amblyomma kraneveldi (Anastos, 1956) (Aponomma) 64. Amblyomma latepunctatum Tonelli-Rondelli, 1939. This species was previously confused with A. incisum and with A. scalpturatum (Guglielmone et al. 2009). 65. Amblyomma latum Koch, 1844 (Aponomma) 66. Amblyomma lepidum Dönitz, 1909 67. Amblyomma limbatum Neumann, 1899 68. Amblyomma loculosum Neumann, 1907 69. Amblyomma longirostre (Koch, 1844) 70. Amblyomma macfarlandi Keirans, Hoogstraal and Clifford, 1973 71. Amblyomma macropi Roberts, 1953 72. Amblyomma maculatum Koch, 1844 73. Amblyomma marmoreum Koch, 1844 74. Amblyomma moreliae (Koch, 1867) 75. Amblyomma moyi Roberts, 1953 76. Amblyomma multipunctum Neumann, 1899 77. Amblyomma naponense (Packard, 1869) 78. Amblyomma neumanni Ribaga, 1902. Nava et al. (2009 a) state that the description by Voltzit (2007) of A. neumanni actually applies to A. parvitarsum. 79. Amblyomma nitidum Hirst and Hirst, 1910. See paragraph “ i ” above our list of Ixodidae. 80. Amblyomma nodosum Neumann, 1899 81. Amblyomma nuttalli Dönitz, 1909 82. Amblyomma oblongoguttatum Koch, 1844 83. Amblyomma orlovi (Kolonin, 1992) (Aponomma). This species is considered tentatively valid in Guglielmone et al. (2009), who nonetheless strongly suggest that it is a synonym of A. transversale. Guglielmone et al. (2009) err in listing the date of description as 1995. 84. Amblyomma ovale Koch, 1844 85. Amblyomma pacae Aragão, 1911 86. Amblyomma papuanum Hirst, 1914 87. Amblyomma parkeri Fonseca and Aragão, 1952. Kolonin (2009) expresses doubt about the status of this species, but Labruna et al. (2009 a) present sound evidence for its validity. 88. Amblyomma parvitarsum Neumann, 1901. See A. neumanni. 89. Amblyomma parvum Aragão, 1908 90. Amblyomma pattoni (Neumann, 1910) (Aponomma) 91. Amblyomma paulopunctatum Neumann, 1899 92. Amblyomma pecarium Dunn, 1933 93. Amblyomma personatum Neumann, 1901 94. Amblyomma pictum Neumann, 1906 95. Amblyomma pilosum Neumann, 1899 96. Amblyomma pomposum Dönitz, 1909 97. Amblyomma postoculatum Neumann, 1899 98. Amblyomma pseudoconcolor Aragão, 1908 99. Amblyomma pseudoparvum Guglielmone, Mangold and Keirans, 1990 100. Amblyomma quadricavum (Schulze, 1941) 101. Amblyomma rhinocerotis (de Geer, 1778) 102. Amblyomma robinsoni Warburton, 1927 103. Amblyomma romitii Tonelli-Rondelli, 1939. This species was previously considered a synonym of A. extraoculatum (Guglielmone et al. 2009). 104. Amblyomma rotundatum Koch, 1844 105. Amblyomma sabanerae Stoll, 1894 106. Amblyomma scalpturatum Neumann, 1906. See A. latepunctatum. 107. Amblyomma scutatum Neumann, 1899 108. Amblyomma soembawense (Anastos, 1956) (Aponomma) 109. Amblyomma sparsum Neumann, 1899 110. Amblyomma sphenodonti (Dumbleton, 1943) (Aponomma). Miller et al. (2007) believe that this species, and possibly A. elaphense, should be classified in a genus other than Amblyomma. 111. Amblyomma splendidum Giebel, 1877 112. Amblyomma squamosum Kohls, 1953 113. Amblyomma supinoi Neumann, 1904 114. Amblyomma sylvaticum (de Geer, 1778) 115. Amblyomma tapirellum Dunn, 1933 116. Amblyomma testudinarium Koch, 1844 117. Amblyomma tholloni Neumann, 1899 118. Amblyomma tigrinum Koch, 1844 119. Amblyomma torrei Pérez Vigueras, 1934 120. Amblyomma transversale (Lucas, 1845) (Aponomma). Most authors consider 1844 the year of description of A. transversale, but the name Ixodes transversalis in Lucas (1844) lacks a description (i. e., it is a nomen nudum), and this situation was amended in Lucas (1845). See A. orlovi. 121. Amblyomma triguttatum Koch, 1844 122. Amblyomma trimaculatum (Lucas, 1878) (Aponomma) 123. Amblyomma triste Koch, 1844 124. Amblyomma tuberculatum Marx, 1894 125. Amblyomma usingeri Keirans, Hoogstraal and Clifford, 1973 126. Amblyomma varanense (Supino, 1897) (Aponomma). Kolonin (2009) considers A. varanense a synonym of A. fuscolineatum (both are treated as species of Aponomma) but without presenting evidence. We believe A. varanense to be valid. 127. Amblyomma variegatum (Fabricius, 1794) 128. Amblyomma varium Koch, 1844 129. Amblyomma vikirri Keirans, Bull and Duffield, 1996 130. Amblyomma williamsi Banks, 1924 1. Anomalohimalaya cricetuli Teng and Huang, 1981. Deng et al. (1999) consider this species a synonym of A. lotozkyi but without explanation. We therefore maintain the validity of A. cricetuli. 2. Anomalohimalaya lamai Hoogstraal, Kaiser and Mitchell, 1970. This is the type species of the genus Anomalohimalaya. 3. Anomalohimalaya lotozkyi Filippova and Panova, 1978. See A. cricetuli. 1. Bothriocroton auruginans (Schulze, 1936) (Aponomma) 2. Bothriocroton concolor (Neumann, 1899) (Aponomma). See B. oudemansi. 3. Bothriocroton glebopalma (Keirans, King and Sharrad, 1994) (Aponomma). This is the type species of the genus Bothriocroton, by original designation (Klompen et al. 2002); it was originally named Aponomma glebopalma. 4. Bothriocroton hydrosauri (Denny, 1843) (Aponomma). See B. tachyglossi. 5. Bothriocroton oudemansi (Neumann, 1910) (Aponomma). This species was considered a synonym of B. concolor, but there is now sound scientific evidence for its validity as a species (Guglielmone et al. 2009). 6. Bothriocroton tachyglossi (Roberts, 1953) (Aponomma). This species was considered a synonym of B. hydrosauri, but there is now convincing evidence for its validity (Guglielmone et al. 2009). 7. Bothriocroton undatum (Fabricius, 1775) (Aponomma). This name is considered invalid by Kolonin (2009). See B. decorosum, paragraph “ ii ” above our list of Ixodidae. 1. Compluriscutula vetulum Poinar and Buckley, 2008. This is the type species of the fossil genus Compluriscutula. It is not included in the list of Kolonin (2009). 1. Cornupalpatum burmanicum Poinar and Brown, 2003. This is the type species of the fossil genus Cornupalpatum. It is not included in the list of Kolonin (2009). 2. Cosmiomma hippopotamensis (Denny, 1843). This is the type species of the monotypic genus Cosmiomma. It was originally named Ixodes hippopotamensis. 1. Dermacentor abaensis Teng, 1963. This species is similar to D. everestianus but is provisionally considered valid in Guglielmone et al. (2009) because there has been no definitive study to support this synonymy. One of us (DAA) is currently comparing the types of D. abaensis, D. everestianus and D. birulai Olenev, 1927. Therefore, additional information on the specific status of these taxa should be forthcoming. 2. Dermacentor albipictus (Packard, 1869) 3. Dermacentor andersoni Stiles, 1908 4. Dermacentor asper Arthur, 1960. Kolonin (2009) considers D. asper a probable synonym of D. sinicus but presents no evidence for this statement. 5. Dermacentor atrosignatus Neumann, 1906 6. Dermacentor auratus Supino, 1897 7. Dermacentor circumguttatus Neumann, 1897 8. Dermacentor compactus Neumann, 1901 9. Dermacentor confragus (Schulze, 1933). Originally spelled confractus, the name was later corrected to confragus. The type specimens are currently being examined by one of us (TNP). We consider this name valid until studies of the type material permit a conclusive statement. Kolonin (2009) excludes this name from his list of ixodid ticks of the world. 10. Dermacentor dispar Cooley, 1937 11. Dermacentor dissimilis, Cooley 1947 12. Dermacentor everestianus Hirst, 1926. See D. abaensis. 13. Dermacentor halli McIntosh, 1931 14. Dermacentor hunteri Bishopp, 1912 15. Dermacentor imitans Warburton, 1933 16. Dermacentor latus Cooley, 1937 17. Dermacentor marginatus (Sulzer, 1776). See D. niveus and D. ushakovae. 18. Dermacentor montanus Filippova and Panova, 1974 19. Dermacentor nitens Neumann, 1897 (Anocentor). This is the type species of the genus Anocentor. 20. Dermacentor niveus Neumann, 1897. Kolonin (2009) lists this species as a synonym of D. daghestanicus Olenev, 1928, but, in fact, the latter name is a junior synonym of D. niveus (Guglielmone et al. 2009). Estrada-Peña and Estrada-Peña (1991) examined part of the syntype series of D. niveus (Cherestanek, Iran, ex Ovis aries, 1882, loaned by Prof. P. - C. Morel), concluding that this species is conspecific with D. marginatus, a view shared by Moshaverinia et al. (2009). A wider comparative study of D. marginatus, D. niveus and D. ushakovae appears to be needed to further demonstrate the validity of these taxa. We consider D. niveus provisionally valid while awaiting the results of this comparison. See also D. ushakovae. 21. Dermacentor nuttalli Olenev, 1928 22. Dermacentor occidentalis Marx, 1892 23. Dermacentor parumapertus Neumann, 1901 24. Dermacentor pavlovskyi Olenev, 1927 25. Dermacentor pomerantzevi Serdjukova, 1951 26. Dermacentor raskemensis Pomerantzev, 1946 27. Dermacentor reticulatus (Fabricius, 1794). This is the type species of the genus Dermacentor. It was originally named Acarus reticulatus. 28. Dermacentor rhinocerinus (Denny, 1843) 29. Dermacentor silvarum Olenev, 1931 30. Dermacentor sinicus Schulze, 1932. See D. asper. 31. Dermacentor steini (Schulze, 1933) 32. Dermacentor taiwanensis Sugimoto, 1935 33. Dermacentor ushakovae Filippova and Panova, 1987. Guglielmone et al. (2009) state that Camicas et al. (1998) consider D. ushakovae a junior synonym of D. niveus, while one of us (AEP) regards this species as a junior synonym of D. marginatus. However, we have elected to recognize the validity of D. ushakovae until type comparisons clarify its status. See also D. niveus. 34. Dermacentor variabilis (Say, 1821) 1. Haemaphysalis aborensis Warburton, 1913 2. Haemaphysalis aciculifer Warburton, 1913 3. Haemaphysalis aculeata Lavarra, 1904 4. Haemaphysalis adleri Feldman-Muhsam, 1951 5. Haemaphysalis anomala Warburton, 1913 6. Haemaphysalis anomaloceraea Teng, 1984. Guglielmone et al. (2009) state that Camicas et al. (1998) consider this species a synonym of H. shimoga, but we continue to treat it as valid because there are no published grounds for synonymization. Kolonin (2009) considers both taxa (H. anomaloceraea and H. shimoga) to be synonyms of H. taiwana but presents no justification for this position. 7. Haemaphysalis anoplos Hoogstraal, Uilenberg and Klein, 1967 8. Haemaphysalis aponommoides Warburton, 1913 9. Haemaphysalis asiatica (Supino, 1897) 10. Haemaphysalis atheruri Hoogstraal, Trapido and Kohls, 1965 11. Haemaphysalis bancrofti Nuttall and Warburton, 1915 12. Haemaphysalis bandicota Hoogstraal and Kohls, 1965 13. Haemaphysalis bartelsi Schulze, 1938 14. Haemaphysalis bequaerti Hoogstraal, 1956 15. Haemaphysalis birmaniae Supino, 1897 16. Haemaphysalis bispinosa Neumann, 1897 17. Haemaphysalis borneata Hoogstraal, 1971 18. Haemaphysalis bremneri Roberts, 1963 19. Haemaphysalis calcarata Neumann, 1902 20. Haemaphysalis calva Nuttall and Warburton, 1915 21. Haemaphysalis campanulata Warburton, 1908 22. Haemaphysalis canestrinii (Supino, 1897) 23. Haemaphysalis capricornis Hoogstraal, 1966 24. Haemaphysalis caucasica Olenev, 1928 25. Haemaphysalis celebensis Hoogstraal, Trapido and Kohls, 1965 26. Haemaphysalis chordeilis (Packard, 1869) 27. Haemaphysalis cinnabarina Koch, 1844. This species is not included in Kolonin´s (2009) list of ixodid ticks. 28. Haemaphysalis colasbelcouri (Santos Dias, 1958). Originally named Aponomma colasbelcouri Santos Dias, 1958, this species is the senior synonym of H. vietnamensis (see H. vietnamensis, paragraph “ iii ” above our list of Ixodidae) (Guglielmone et al. 2009). 29. Haemaphysalis colesbergensis Apanaskevich and Horak, 2008. This species is not included in Kolonin´s (2009) list of ixodid ticks. 30. Haemaphysalis concinna Koch, 1844. This is the type species of the genus Haemaphysalis. See also H. filippovae. 31. Haemaphysalis cooleyi Bedford, 1929 32. Haemaphysalis cornigera Neumann, 1897 33. Haemaphysalis cornupunctata Hoogstraal and Varma, 1962 34. Haemaphysalis cuspidata Warburton, 1910 35. Haemaphysalis dangi Phan Trong, 1977 36. Haemaphysalis danieli Č erný and Hoogstraal, 1977. See paragraph “ iv ” above our list of Ixodidae. Kolonin (2009) considers specimens of this taxon from China a synonym of H. pospelovashtromae but provides no supporting evidence. 37. Haemaphysalis darjeeling Hoogstraal and Dhanda, 1970 38. Haemaphysalis davisi Hoogstraal, Dhanda and Bhat, 1970 39. Haemaphysalis demidovae Emel´yanova, 1978 40. Haemaphysalis doenitzi Warburton and Nuttall, 1909. See H. pavlovskyi and H. phasiana. 41. Haemaphysalis elliptica (Koch, 1844) 42. Haemaphysalis elongata Neumann, 1897 43. Haemaphysalis erinacei Pavesi, 1884 44. Haemaphysalis eupleres Hoogstraal, Kohls and Trapido, 1965 45. Haemaphysalis filippovae Bolotin, 1979. Although Kolonin (2009) considers H. filippovae a synonym of H. concinna, Guglielmone et al. (2009) provide strong arguments for supporting the validity of this taxon. 46. Haemaphysalis flava Neumann, 1897 47. Haemaphysalis formosensis Neumann, 1913 48. Haemaphysalis fossae Hoogstraal, 1953 49. Haemaphysalis fujisana Kitaoka, 1970 50.

Haemaphysalis kitaokai Hoogstraal, 1969 75. Haemaphysalis knobigera Prakasan and Ramani, 2007. The original description of this species is very poor and we strongly doubt its validity (Guglielmone et al. 2009), but we include it here pending further studies. Kolonin (2009) does not include H. knobigera in his list of the Ixodidae of the world. 76. Haemaphysalis koningsbergeri Warburton and Nuttall, 1909 77. Haemaphysalis kopetdaghica Kerbabaev, 1962.

Haemaphysalis pavlovskyi Pospelova-Shtrom, 1935. Guglielmone et al. (2009) provide strong arguments for the validity of H. pavlovskyi, but Kolonin (2009) regards this species as a synonym of H. doenitzi, a position that we consider unjustified. 117.

(1998) in stressing that the correct Latin epithet for this species is quinghaiensis, not qinghaiensis, even though the latter spelling appears in the original description. 128.

Hyalomma aegyptium (Linnaeus, 1758). This is the type species of the genus Hyalomma, as discussed in Filippova (1984). It was originally named Acarus aegyptius. See also H. dromedarii. 2. Hyalomma albiparmatum Schulze, 1919. Apanaskevich & Horak (2008) consider H. albiparmatum a valid species but did not discount the possibility that it may be conspecific with H. truncatum. See also H. nitidum. 3. Hyalomma anatolicum Koch, 1844. See H. excavatum. 4. Hyalomma arabica Pegram, Hoogstraal and Wassef, 1982 5. Hyalomma asiaticum Schulze and Schlottke, 1930 6. Hyalomma brevipunctata Sharif, 1928 7. Hyalomma dromedarii Koch, 1844. This is the type species of the genus Hyalomma in Camicas et al. (1998), but we agree with Filippova (1984), who considers H. aegyptium to be the type. 8. Hyalomma excavatum Koch, 1844. This species was previously classified as a subspecies of H. anatolicum (Guglielmone et al. 2009). 9. Hyalomma franchinii Tonelli-Rondelli, 1932. 10. Hyalomma glabrum Delpy, 1949. This name was until recently considered a synonym of H. turanicum (Guglielmone et al. 2009). 11. Hyalomma hussaini Sharif, 1928 12. Hyalomma hystricis Dhanda and Raja, 1974 13. Hyalomma impeltatum Schulze and Schlottke, 1930. See H. erythraeum, paragraph “ v ” above our list of Ixodidae. 14. Hyalomma impressum Koch, 1844 15. Hyalomma isaaci Sharif, 1928. This species was previously classified as a subspecies of H. marginatum (Guglielmone et al. 2009). 16. Hyalomma kumari Sharif, 1928 17. Hyalomma lusitanicum Koch, 1844 18. Hyalomma marginatum Koch, 1844. See H. isaaci, H. rufipes and H. turanicum. 19. Hyalomma nitidum Schulze, 1919. Apanaskevich & Horak (2008) consider H. nitidum a valid species but left open the possibility that it may be conspecific with H. truncatum. See also H. albiparmatum. 20. Hyalomma punt Hoogstraal, Kaiser and Pedersen, 1969 21. Hyalomma rhipicephaloides Neumann, 1901 22. Hyalomma rufipes Koch, 1844. This species was previously classified as a subspecies of H. marginatum (Guglielmone et al. 2009). 23. Hyalomma schulzei Olenev, 1931 24. Hyalomma scupense Schulze, 1919. Until recently, this species was known as H. detritum Schulze, 1919 by many Western workers. Because this is an economically important tick, Guglielmone et al. (2009) proposed referring to it as H. scupense (= H. detritum) in order to avoid confusion. 25. Hyalomma somalicum Tonelli-Rondelli, 1935. This taxon was recently resurrected by Apanaskevich and Horak (2009). 26. Hyalomma truncatum Koch, 1844. See H. albiparmatum and H. nitidum. 27. Hyalomma turanicum Pomerantzev, 1946. This species was previously classified as a subspecies of H. marginatum (Guglielmone et al. 2009). Kolonin (2009) excludes H. turanicum from his list of ixodid ticks of the world. 1. Ixodes abrocomae Lahille, 1916. Some authors have listed the year 1916 for Lahille´s original description of Ixodes abrocomae, while others have used the year 1917. An inquiry to the U. S Library of Congress failed to resolve the problem. A request to the Sociedad Chilena de Biología (publisher of Revista Chilena de Historia Natural, where the description of I. abrocomae appeared) was not answered. We consider 1916 as the year of description of I. abrocomae. See also I. sigelos. 2. Ixodes acuminatus Neumann, 1901. See I. redikorzevi. 3. Ixodes acutitarsus (Karsch, 1880) 4. Ixodes affinis Neumann, 1899 5. Ixodes albignaci Uilenberg and Hoogstraal, 1969 6. Ixodes alluaudi Neumann, 1913 7. Ixodes amarali Fonseca, 1935 8. Ixodes amersoni Kohls, 1966 9. Ixodes anatis Chilton, 1904. Some authors consider the name of this species to be I. apteridis Maskell, 1897, a nomen nudum (Guglielmone et al. 2009). 10. Ixodes andinus Kohls, 1956 11. Ixodes angustus Neumann, 1899 12. Ixodes antechini Roberts, 1960 13. Ixodes apronophorus Schulze, 1924 14. Ixodes arabukiensis Arthur, 1959. This species is very similar to I. djaronensis, but Guglielmone et al. (2009) consider it valid pending a comparison of types. Kolonin (2009) excludes I. arabukiensis from his list of Ixodidae. 15. Ixodes aragaoi Fonseca, 1935 16. Ixodes arboricola Schulze and Schlottke, 1930 17. Ixodes arebiensis Arthur, 1956 18. Ixodes asanumai Kitaoka, 1973 19. Ixodes aulacodi Arthur, 1956 20. Ixodes auriculaelongae Arthur, 1958 21. Ixodes auritulus Neumann, 1904. This name is thought to represent an Ixodes species group (González-Acuña et al. 2009). 22. Ixodes australiensis Neumann, 1904 23. Ixodes baergi Cooley and Kohls, 1942 24. Ixodes bakeri Arthur and Clifford, 1961 25. Ixodes banksi Bishopp, 1911 26. Ixodes bedfordi Arthur, 1959 27. Ixodes bequaerti Cooley and Kohls, 1945 28. Ixodes berlesei Birula, 1895 29. Ixodes bivari Santos Dias, 1990. Kolonin (2009) does not include I. bivari in his list; apparently he regards this name as a synonym of I. ventalloi. One of us (AEP) examined the types of I. bivari and found that they differ from I. ventalloi, especially in the morphology of the basis capituli. Therefore, we treat I. bivari as valid. 30. Ixodes boliviensis Neumann, 1904. This species is very similar to I. diversifossus, but Guglielmone et al. (2009) consider it valid pending a comparison of types. 31. Ixodes brewsterae Keirans, Clifford and Walker, 1982 32. Ixodes browningi Arthur, 1956 33. Ixodes brumpti Morel, 1965 34. Ixodes brunneus Koch, 1844 35. Ixodes calcarhebes Arthur and Zulu, 1980 36. Ixodes caledonicus Nuttall, 1910 37. Ixodes canisuga Johnston, 1849. Teng and Jiang (1991) and Kolonin (2009) consider I. canisuga a synonym of I. crenulatus but provide no supporting evidence; we therefore have retained I. canisuga as valid. 38. Ixodes capromydis Èern 1966 39. Ixodes catherinei Keirans, Clifford and Walker, 1982 40. Ixodes cavipalpus Nuttall and Warburton, 1908 41. Ixodes ceylonensis Kohls, 1950 42. Ixodes chilensis Kohls, 1956 43. Ixodes colasbelcouri Arthur, 1957 44. Ixodes collocaliae Schulze, 1937 45. Ixodes columnae Takada and Fujita, 1992 46. Ixodes conepati Cooley and Kohls, 1943 47.

Ixodes cornuae Arthur, 1960 53. Ixodes cornuatus Roberts, 1960 54. Ixodes cornutus Lotozky, 1956. Camicas et al. (1998) consider I. cornutus a synonym of I. rugicollis, although Filippova (1977) redescribed I. cornutus as valid. We treat this species as tentatively valid, pending type comparison with I. rugicollis. 55. Ixodes corwini Keirans, Clifford and Walker, 1982 56. Ixodes crenulatus Koch, 1844. See I. canisuga and I. prokopjevi 57. Ixodes cuernavacensis Kohls and Clifford, 1966 58. Ixodes cumulatimpunctatus Schulze, 1943 59. Ixodes dampfi Cooley, 1943 60. Ixodes daveyi Nuttall, 1913 61.

Ixodes diversifossus Neumann, 1899. Kolonin (2009) does not include this species in his list of world Ixodidae. See also I. boliviensis. 67. Ixodes djaronensis Neumann, 1907. See I. arabukiensis 68. Ixodes domerguei Uilenberg and Hoogstraal, 1965 69. Ixodes downsi Kohls, 1957 70. Ixodes drakensbergensis Clifford, Theiler and Baker, 1975 71. Ixodes eadsi Kohls and Clifford, 1964 72. Ixodes eastoni Keirans and Clifford, 1983 73. Ixodes eichhorni Nuttall, 1916 74. Ixodes eldaricus Dzhaparidze, 1950 75. Ixodes elongatus Bedford, 1929 76. Ixodes eudyptidis Maskell, 1885 77. Ixodes euplecti Arthur, 1958 78. Ixodes evansi Arthur, 1956 79. Ixodes fecialis Warburton and Nuttall, 1909 80. Ixodes festai Tonelli-Rondelli, 1926 81. Ixodes filippovae Č erný, 1961. Kolonin (2009) does not include this species in his list of ixodid ticks of the world. He is probably following Filippova (1977), who considers I. filippovae a synonym of I. crenulatus. In fact, the status of I. filippovae is questionable and we list this species as provisionally valid while awaiting further studies. 82. Ixodes fossulatus Neumann, 1899 83. Ixodes frontalis (Panzer, 1798) 84. Ixodes fuscipes Koch, 1844 85. Ixodes galapagoensis Clifford and Hoogstraal, 1980 86. Ixodes ghilarovi Filippova and Panova, 1988 87.

Ixodes kashmiricus Pomerantzev, 1948. Guglielmone et al. (2009) asserted that the spelling kaschmiricus was correct. However, Pomerantzev (1950) amended the spelling kaschmiricus to kashmiricus, the valid name for this species. 106. Ixodes kazakstani Olenev and Sorokoumov, 1934 107. Ixodes kerguelenensis Andr é and Colas-Belcour, 1942 108. Ixodes kingi Bishopp, 1911 109. Ixodes kohlsi Arthur, 1955 110. Ixodes kopsteini (Oudemans, 1926) 111.

Kolonin (2009) considers I. maslovi a synonym of I. persulcatus, but Guglielmone et al. (2009) provide arguments for its validity. 130. Ixodes matopi Spickett, Keirans, Norval and Clifford, 1981 131.

Ixodes persulcatus Schulze, 1930. See also I. maslovi and I. sachalinensis. 170. Ixodes petauristae Warburton, 1933 171. Ixodes philipi Keirans and Kohls, 1970 172. Ixodes pilosus Koch, 1844. McKay (1994) considers that there are three species under the name I. pilosus. Two of us (DAA and IGH) and co-workers are currently studying I. pilosus and its alleged sibling species. 173. Ixodes pomerantzevi Serdjukova, 1941. Guglielmone et al. (2009) asserted that the spelling pomeranzevi was correct. However, Pomerantzev (1950) amended the spelling pomeranzevi to pomerantzevi, the valid name for this species. 174. Ixodes pomerantzi Kohls, 1956 175. Ixodes priscicollaris Schulze, 1932 176. Ixodes procaviae Arthur and Burrow, 1957 177. Ixodes prokopjevi (Emel´yanova, 1979). Kolonin (2009) appears to consider this species a likely synonym of I. crenulatus, but we find no reason to declare I. prokopjevi invalid. 178. Ixodes radfordi Kohls, 1948 179. Ixodes rageaui Arthur, 1958 180. Ixodes randrianasoloi Uilenberg and Hoogstraal, 1969 181. Ixodes rasus Neumann, 1899 182. Ixodes redikorzevi Olenev, 1927. Kolonin (2009) considers this species a synonym of I. acuminatus, but we regard it as provisionally valid. 183. Ixodes rhabdomysae Arthur, 1959 184. Ixodes ricinus (Linnaeus, 1758). This is the type species of the genus Ixodes; it was originally named Acarus ricinus. 185. Ixodes rothschildi Nuttall and Warburton, 1911 186. Ixodes rotundatus Arthur, 1958 187. Ixodes rubicundus Neumann, 1904 188. Ixodes rubidus Neumann, 1901 189. Ixodes rugicollis Schulze and Schlottke, 1930. See I. cornutus. 190. Ixodes rugosus Bishopp, 1911 191. Ixodes sachalinensis Filippova, 1971. Kolonin (2009) considers I. sachalinensis a synonym of I. persulcatus, but Guglielmone et al. (2009) have found no evidence to support this position. 192. Ixodes scapularis Say, 1821 193. Ixodes schillingsi Neumann, 1901 194. Ixodes schulzei Aragão and Fonseca, 1951 195. Ixodes sculptus Neumann, 1904 196. Ixodes semenovi Olenev, 1929 197. Ixodes shahi Clifford, Hoogstraal and Kohls, 1971 198. Ixodes siamensis Kitaoka and Suzuki, 1983. Kolonin (2009) considers I. siamensis a synonym of I. ovatus, but Guglielmone et al. (2009) treat it as provisionally valid. 199. Ixodes sigelos Keirans, Clifford and Corwin, 1976. In Camicas et al. (1998), I. sigelos is listed as a synonym of I. abrocomae Lahille, 1916, but Guglielmone et al. (2009) found no evidence for this arrangement and declared both names valid. Recently, Guglielmone et al. (in press) redescribed the male and described the female of I. abrocomae, thereby settling this controversy. 200. Ixodes signatus Birula, 1895 201. Ixodes simplex Neumann, 1906 202. Ixodes sinaloa Kohls and Clifford, 1966 203. Ixodes sinensis Teng, 1977 204. Ixodes soricis Gregson, 1942 205. Ixodes spinae Arthur, 1958 206.

Ixodes subterraneus Filippova, 1961. This species was originally named I. subterranus in Filipppova (1961), but amended to I. subterraneus in Filippova (1977). 212. Ixodes succineus Weidner, 1964. Fossil. This species is not included in Kolonin (2009). 213. Ixodes taglei Kohls, 1969 214. Ixodes tamaulipas Kohls and Clifford, 1966 215. Ixodes tancitarius Cooley and Kohls, 1942 216.

Ixodes werneri Kohls, 1950 241. Ixodes woodi Bishopp, 1911 242. Ixodes zaglossi Kohls, 1960 243. Ixodes zairensis Keirans, Clifford and Walker, 1982 1. Nosomma monstrosum (Nuttall and Warburton, 1908). This is the type species of the formerly monotypic genus Nosomma; it was originally named Hyalomma monstrosum. 2. Nosomma keralensis Prakasan and Ramani, 2007. The original description of this species is very poor and we strongly doubt its validity (Guglielmone et al. 2009), but we include it here pending type comparison with N. monstrosum, which should readily clarify its status. Kolonin (2009) does not include this species in his list of the Ixodidae of the world. 1. Rhipicentor bicornis Nuttall and Warburton, 1908. This is the type species of the genus Rhipicentor. 2. Rhipicentor nuttalli Cooper and Robinson, 1908 1. Rhipicephalus annulatus (Say, 1821) (Boophilus). This is the type species of the genus Boophilus. This species was originally named Ixodes annulatus. 2. Rhipicephalus appendiculatus Neumann, 1901 3. Rhipicephalus aquatilis Walker, Keirans and Pegram, 1993 4. Rhipicephalus armatus Pocock, 1900 5. Rhipicephalus arnoldi Theiler and Zumpt, 1949 6. Rhipicephalus aurantiacus Neumann, 1907. Guglielmone et al. (2009) note that this tick is considered a synonym of R. ziemanni by some authors, but because there has been no comparison of types, we provisionally regard R. aurantiacus as valid. Kolonin (2009) does not include R. aurantiacus in his list of world Ixodidae. 7. Rhipicephalus bequaerti Zumpt, 1949 8. Rhipicephalus bergeoni Morel and Balis, 1976 9. Rhipicephalus boueti Morel, 1957 10. Rhipicephalus bursa Canestrini and Fanzago, 1878 11. Rhipicephalus camicasi Morel, Mouchet and Rodhain, 1976 12. Rhipicephalus capensis Koch, 1844 13. Rhipicephalus carnivoralis Walker, 1966 14. Rhipicephalus cliffordi Morel, 1965. Guglielmone et al. (2009) note that this tick has been considered a synonym of R. pseudolongus, but because there has been no comparison of types, we provisionally regard R. cliffordi as valid. Kolonin (2009) does not share this opinion. 15. Rhipicephalus complanatus Neumann, 1911 16. Rhipicephalus compositus Neumann, 1897 17. Rhipicephalus cuspidatus Neumann, 1906 18. Rhipicephalus decoloratus Koch, 1844 (Boophilus) 19. Rhipicephalus deltoideus Neumann, 1910 20. Rhipicephalus distinctus Bedford, 1932 21. Rhipicephalus duttoni Neumann, 1907 22. Rhipicephalus dux Dönitz, 1910 23. Rhipicephalus evertsi Neumann, 1897 24. Rhipicephalus exophthalmos Keirans and Walker, 1993 25. Rhipicephalus follis Dönitz, 1910 26. Rhipicephalus fulvus Neumann, 1913 27. Rhipicephalus geigyi Aeschlimann and Morel, 1965 (Boophilus) 28. Rhipicephalus gertrudae Feldman-Muhsam, 1960 29. Rhipicephalus glabroscutatum Du Toit, 1941 30. Rhipicephalus guilhoni Morel and Vassiliades, 1963 31. Rhipicephalus haemaphysaloides Supino, 1897 32. Rhipicephalus humeralis Tonelli-Rondelli, 1926 33. Rhipicephalus hurti Wilson, 1954 34. Rhipicephalus interventus Walker, Pegram and Keirans, 1995 35. Rhipicephalus jeanneli Neumann, 1913 36. Rhipicephalus kochi Dönitz, 1905 37. Rhipicephalus kohlsi (Hoogstraal and Kaiser, 1960) (Boophilus) 38. Rhipicephalus leporis Pomerantzev, 1946 39. Rhipicephalus longiceps Warburton, 1912 40. Rhipicephalus longicoxatus Neumann, 1905 41. Rhipicephalus longus Neumann, 1907. See R. pseudolongus. 42. Rhipicephalus lounsburyi Walker, 1990 43. Rhipicephalus lunulatus Neumann, 1907 44. Rhipicephalus maculatus Neumann, 1901 45. Rhipicephalus masseyi Nuttall and Warburton, 1908 46. Rhipicephalus microplus (Canestrini, 1888) (Boophilus). Some authors have listed the year 1887 for the original description of Rhipicephalus microplus (the species was described as Haemophysalis [sic] micropla), while others have used the year 1888. An inquiry to the U. S. Library of Congress has shown that Canestrini (1887) was actually published in Padova by Stabilimento Prosperini in 1888; therefore, we recognize the latter year for the description of R. microplus. A recent study by Labruna et al. (2009 b) presents evidence that populations of R. microplus from Australia are not conspecific with Afrotropical and Neotropical populations, although Afrotropical and Neotropical populations are conspecific. 47. Rhipicephalus moucheti Morel, 1965 48. Rhipicephalus muehlensi Zumpt, 1943 49. Rhipicephalus muhsamae Morel and Vassiliades, 1965 50. Rhipicephalus neumanni Walker, 1990 51. Rhipicephalus nitens Neumann, 1904 52. Rhipicephalus oculatus Neumann, 1901 53. Rhipicephalus oreotragi Walker and Horak, 2000 54. Rhipicephalus pilans Schulze, 1935 55. Rhipicephalus planus Neumann, 1907 56. Rhipicephalus praetextatus Gerstäcker, 1873 57. Rhipicephalus pravus Dönitz, 1910 58. Rhipicephalus pseudolongus Santos Dias, 1953. Guglielmone et al. (2009) note that this tick is considered a synonym of R. longus by some authors, but no evidence has been forthcoming to support such a view; therefore, we regard R. pseudolongus as tentatively valid. See also R. cliffordi. 59. Rhipicephalus pulchellus (Gerstäcker, 1873) 60. Rhipicephalus pumilio Schulze, 1935 61. Rhipicephalus punctatus Warburton, 1912. See R. serranoi. 62. Rhipicephalus pusillus Gil Collado, 1936 63. Rhipicephalus ramachandrai Dhanda, 1966 64. Rhipicephalus rossicus Yakimov and Kol-Yakimova, 1911 65. Rhipicephalus sanguineus (Latreille, 1806). This is the type species of the genus Rhipicephalus; it was originally named Ixodes sanguineus. 66. Rhipicephalus scalpturatus Santos Dias, 1959 67. Rhipicephalus schulzei Olenev, 1929 68. Rhipicephalus sculptus Warburton, 1912 69. Rhipicephalus senegalensis Koch, 1844 70. Rhipicephalus serranoi Santos Dias, 1950. Guglielmone et al. (2009) note that this species is considered a synonym of R. punctatus by some authors, but characters useful for separating the two species have been published. 71. Rhipicephalus simpsoni Nuttall, 1910 72. Rhipicephalus simus Koch, 1844 73. Rhipicephalus sulcatus Neumann, 1908 74. Rhipicephalus supertritus Neumann, 1907 75. Rhipicephalus tetracornus Kitaoka and Suzuki, 1983. Kolonin (2009) excludes R. tetracornus from his list of world Ixodidae, but the holotype nymph exists and no evidence has been proffered to support synonymization (Guglielmone et al. 2009). 76. Rhipicephalus theileri Bedford and Hewitt, 1925 77. Rhipicephalus tricuspis Dönitz, 1906 78. Rhipicephalus turanicus Pomerantzev, 1940. While most Western workers list the year 1936 for the original description of R. turanicus, we follow Filippova (1997), who considers 1940 to be the correct year. 79. Rhipicephalus warburtoni Walker and Horak, 2000 80. Rhipicephalus zambeziensis Walker, Norval and Corwin, 1981 81. Rhipicephalus ziemanni Neumann, 1904. See R. aurantiacus. 82.
