Abstract
Tehuacania Endrödi is a monotypic genus endemic to Mexico (Endrödi 1975, 1985; Morón et al. 1997). The only species known in the genus, T. howdeni Endrödi, has a restricted distribution and represents the rarest of the Oryctini from Mexico. For more than 30 years the female remained unknown. Recently, three female specimens were collected in arid lands in the vicinity of Santa Maria Coapan and Santa Maria La Alta in the Valley of Tehuacan, near the site where the holotype and paratype males were collected in 1961.
Studied specimens are deposited in the entomological collections of the Canadian Museum of Nature (CMNC), Ottawa; Instituto Tecnológico de Ciudad Victoria (ITCV), Tamaulipas, Mexico; and the private collections of A. Bitar (CABS) Mexico City and M. A. Morón (MXAL) Xalapa, Veracruz, Mexico.
