TL;DR: Two new genera, Ampliphallus gen. nov. and Guelaguetzia gen.Nov.
Abstract: Two new genera, Ampliphallus gen. nov. and Guelaguetzia gen. nov., are described from material collected in the state of Oaxaca, Mexico. The genus Ampliphallus gen. nov. is monotypic and contains the species A. chimalapaensis sp. nov., from the tropical rain forest of Santa Maria Chimalapa, Oaxaca. The genus Guelaguetzia gen. nov. is composed of two species: G. cuicateca sp. nov. (type species) and G. serrana sp. nov., from pine forests in northern Oaxaca. These genera can be recognized from each other mainly by the armature of leg IV and by the male genitalia; both are also compared with the remaining members of the Stygnopsinae. An identification key for all genera of the subfamily is provided.
TL;DR: Three new species of the genus Philora are described: P. izel and P. nympha exhibit remarkable troglomorphisms, such as depigmentation, absence of eyes and elongation of appendages.
Abstract: Three new species of the genus Philora are described: Philora izel sp. nov., Philora mazateca sp. nov. and Philora nympha sp. nov. Two of these, P. izel and P. nympha exhibit remarkable troglomorphisms (adaptations to life in caves), such as depigmentation, absence of eyes and elongation of appendages. These conditions are discussed and their ocurrence is compared with the other 3 species of the genus that do not exhibit troglomorphisms. A dichotomic key to identify the 5 known species of the genus is provided.
