Calvanese, Victor C., Brescovit, Antonio D., Bonato, Lucio (2019): Revision of the Neotropical species of Aphilodontinae (Geophilomorpha, Geophilidae), with eight new species and a first phylogenetic analysis of the subfamily. Zootaxa 4698 (1): 1-72, DOI: 10.11646/zootaxa.4698.1.1

Description of holotype. Female (IBSP 6172). Entire body: length 7.5, maximum width 0.17. Cephalic plate: sub-rectangular, length 0.20 and maximum width (at about mid-length) 0.13 (length / width ratio 1.53). Antenna: length 0.48, ca. 2.4 times as long as cephalic plate; AA II – XIII length / width ratio 0.55 – 0.70; LAA ca. 4.2 times as long as AA XIII. Clypeus: 2 + 2 LS, 1 + 1 PS, 5 + 5 SCS. Mandible: PL with ca. 20 denticles. First maxillae: TFM length 0.02 and width 0.02; DA with 3 apical and 1 subapical SL; MPC with 2 apical and 1 subapical SL. Second maxillae: left TSM length 0.02 (1.15 times as long as TFM) and maximum width (basal margin) 0.01; left T 3 length 0.01 (0.75 times as long as T 2) and width 0.01 (0.70 times as wide as T 2); both TSM with 1 apical and 1 subapical large SE. Forcipular segment: FTE length 0.07 (0.36 times as long as cephalic plate) and width 0.15 (length / width ratio 0.48); FPT length 0.05 (0.25 times as long as cephalic plate) and width 0.09; FCX length 0.25 and width 0.20 (length / width ratio 1.25); FRL length 0.22, surpassing anterior margin of cephalic plate, and maximum width (basal margin) 0.08; FRL with two denticles in TFF and one in TI; FD 1 relatively large, pointed and without SE, positioned relatively close to FD 2; FD 2 bilobed, with 1 large apical and 1 large subapical SE; FD 3 bilobed, with 1 large apical and 3 smaller subapical SE; DTA relatively large, near the basis of TA; TA 0.48 times as long as TFF. Walking legs: 35 pairs; left FL length 0.17, 0.83 times as long as second leg; left leg 17 length 0.21. Tergum from the first to penultimate leg-bearing segment: TE 17 length 0.09 and width 0.17 (length / width ratio 0.52), with one anterior row of 8 SE and one posterior row of little smaller SE; PT 0.57 times as long as TE and with two parallel rows of 6 SE. Sternum from the first to penultimate leg-bearing segment: STF rectangular, length 0.10 and width 0.08 (length / width ratio 1.2); ST 17 length 0.13 and width 0.09 (length / width ratio 1.4). Ultimate leg-bearing segment: MTL trapezoidal, length 0.07 and maximum width 0.10 (length / width ratio 0.66); UPS exposed and not divided, length 0.01 and width 0.10. Ultimate legs: with two tarsal articles and terminal claw; slightly thickened when compared to penultimate leg; length 0.43, 1.83 times as long as penultimate leg; each CXP with 5 or 6 little COP that are weakly grouped near MTL and 1 COP further away. Postpedal segments: GF with 3 + 3 distal SE. Known variation. Ultimate legs: each coxopleuron with 5 – 7 COP in adults (1 ♀, 4 ♂). Male: ultimate legs with a single tarsal article, little more thickened than in female, without pretarsus; GM biarticulated; GM 1 with 4 or 5 SE in one row; GM 2 with 7 distal SE.

Diagnosis. A species of Mecophilus with: known body length in adults 7.0 – 7.5 mm; cephalic plate subrectangular (Figs 32 B, 40 F); forcipular tergite subrectangular (Figs 32 B, 40 F); denticle of tarsungulum relatively large and positioned close to basis of tarsungulum (Figs 30 A, 32 D); distal denticle of trochanteroprefemur and denticle of femur close to each other (Figs 30 A, 32 D). Recorded specimens: 5, including 1 ♀ and 4 ♂, from a single locality.

Distribution. Brazil — São Paulo: São Roque.

Etymology. The epithet is an adjective and means “ originating in Brazil ” in the Tupi-Guarani language.

Type specimens. Holotype: ♀, from Morro do Cruzeiro, São Roque, São Paulo, Brazil, 15 / 11 / 2017, V. Calvanese col., (IBSP 6172). Paratypes: 4 ♂ (IBSP 6173), same data as holotype. Type locality. Brazil: São Paulo: São Roque: Morro do Cruzeiro: 23 ° 32 ’ 18 ” S, 47 ° 8 ’ 43 ” W. Material examined. BRAZIL: São Paulo: São Roque, Morro do Cruzeiro (23 ° 32 ’ 18 ” S, 47 ° 8 ’ 43 ” W), 15 / 11 / 2017, V. Calvanese col., 1 ♀ [holotype] (IBSP 6172), 4 ♂ [paratypes] (IBSP 6173).
