Ornithodoros coriaceus

New records: OAXACA: 5 F, 7 N, Ixtepec, ND, XII- 1941 (CNAC 001953); 2 F, 18 M, 60 N, Ixtepec, ND, 10 - IV- 1940 (CNAC 001954). Notes: Hoffmann (1930) stated that this species occurs from California to Chiapas, where it is a parasite of small rodents and large wild and domestic mammals, such as deer and cattle; it occasionally attacks humans. Later, Hoffmann (1961) also referred to this species as occurring from California to Oaxaca and Chiapas, again as a pest of cattle and occasionally humans. Hoffmann and López-Campos (2000) cited this species from Baja California, Baja California Sur, Chiapas, Coahuila, Durango, Guerrero, Jalisco, Michoacán, Oaxaca, Sinaloa, and Sonora, listing its hosts as rodents and their burrows, deer, and cattle, while mentioning that it may be found in nests of swallows, and that it is occasionally a human parasite.
