Article
Cavernicolous species that exhibit a high degree of troglomorphism often provide some of the most intriguing evolutionary riddles. For such taxa, the correct systematic arrangement is difficult to determine and becomes problematic when based solely on highly convergent external morphological characters, leading to exaggerated support of spurious re...
Article
Schizomid female flagellum, including the number of “flagellomeres” and the setae, are among the most important taxonomic characters within the order. It is widely used to diagnose genera within both extant families. Despite the traditional use in schizomid taxonomy, the phylogenetic signal of these characters has been only once tested in the syste...

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 ocurr...

Sistema Huautla is the deepest cave system in the Americas at 1560 m and the fifth longest in Mexico at 89,000 m, and it is a mostly vertical network of interconnected passages. The surface landscape is rugged, ranging from 3500 to 2500 masl, intersected by streams and deep gorges. There are numerous dolinas, from hundreds to tens of meters in widt...
Article
Among Opiliones (Arachnida), there are many taxa either with no familial assignment or erroneously located in their current family. This is the case of Ethobunus pilosus, formerly in Phalangodidae and before this work in Zalmoxidae. To assess the phylogenetic position of this taxon, we started with a revision of the male genitalia; followed by the...

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 María Chimalapa, Oaxaca. The genus Guelaguetzia gen. nov. is composed of tw...

From a biological point of view, caves are one of the most exciting environments on Earth, considered as evolutionary laborato- ries due to the adaptive traits (troglomorphisms) usually exhibited by the fauna that inhabit them. Among Opiliones, the family Stygnopsi- dae contains cave-inhabiting members who exhibit some degree of troglomorphic chara...

Dos especies nuevas troglobias del género Serrobunus Goodnight y Goodnight, 1942 son descritas: S. linares sp. nov. y S. paulbryanti sp. nov., provenientes de cuevas de los estados de Nuevo León y Tamaulipas, México, respectivamente. Serrobunus linares sp. nov. puede reconocerse principalmente por características de la dentición queliceral, de la a...

In this work, the holotype of Metaconomma femorale Pickard-Cambridge, 1905 was revised. As a result, the genus Metaconomma Pickard-Cambridge, 1905, a member of the infraorder Grassatores with uncertain family placement, is proposed as a junior synonym of Hoplobunus Banks, 1900 in Stygnopsidae, with the new combination Hoplobunus femoralis comb. nov...

Based on the recently published total evidence phylogeny of the family Stygnopsidae, the genus Paramitraceras Pickard-Cambridge, 1905 was recovered as polyphyletic. As part of the revision of this polyphyletic genus, the Neotropical genus Panzosus Roewer, 1949 stat. rev. is resurrected from its synonymy under Paramitraceras. Panzosus is rediagnosed...

Ortholasmatinae is one of the most striking groups of Opiliones, because its members exhibit a peculiar dorsal ornamentation pattern of cells, formed by fusion of anvil-shaped tubercles. During the systematic revision of several specimens of ortholasmatines, we found specimens with shared morphological characters with two genera Trilasma Goodnight...

Systematic relationships among Laniatores have received considerable attention during the past few years. Many significant taxonomic changes have been proposed, particularly in the superfamily Gonyleptoidea. As part of this superfamily, the basalmost Stygnopsidae is the least known family. In order to propose the first total evidence phylogeny of t...
