摘要：Tityopsis aliciae Armas y Martín-Frías, 1998 is redescribed based on an adult female from the type locality, Tehuantepec, Oaxaca. The holotype, previously the only known specimen, is a subadult female and it is poorly preserved, which led to some inaccuracies in the original description. There were some doubts regarding the type locality, but the finding of an adult female confirms the presence of this genus, the second belonging to the family Buthidae, in Mexico.
