Abstract
A new species of the enigmatic spider genus Mexentypesa (Raven, 1987) from a cloud forest in Hidalgo state, Mexico is described: M. hidalguensis sp. nov. The description of the species is based on both male and female adult specimens. This discovery increases the diversity of the genus to two species: Mexentypesa chiapas (Raven, 1987) and the new species described herein. Additionally, Aptostichus sabinae syn. nov. (=M. chiapas), which was previously described as a different species, is formally synonymized.
