Abstract

Gypogyna Simon, 1900 is revised. Three species are recognized and diagnosed. The type species, Gypogyna forceps Simon, 1900, is redescribed and recorded from several localities in South America. Gypogyna amazonica Ruiz sp. nov. is described based on a male from Manaus, Brazil. Gypogyna mexicana Ruiz & Bustamante sp. nov. is described based on specimens of both sexes from the state of Jalisco, Mexico. In addition, some comments on cheliceral dentiton and genital morphology are discussed.
