Two new species of Endecous Saussure, 1878 (Orthoptera: Grylloidea: Phalangopsidae) from caves in central-western Brazil, with the proposition of a new subgenus to accommodate E. vitreus Bolfarini & Campos, 2023.

The genus Endecous (Orthoptera, Grylloidea, Phalangopsidae) encompasses over 20 species, grouped into four subgenera: E. (Endecous), E. (Pedroecous), E.

Expanding the taxonomic knowledge of Adelosgryllus Mesa amp; Zefa, 2004 (Orthoptera: Grylloidea: Phalangopsidae): description of four new species for Brazilian subterranean habitats.

In this study, four new Brazilian species are described for the genus Adelosgryllus Mesa Zefa, 2004, occurring in Minas Gerais, Tocantins and Par states. Three of these species were found in caves and one was found in endogenous habitats, representing the first record of species form this genus for such habitats. The morphology of the phallic complex was used as the main criterion for distinguishing the new species, the copulatory papilla was also described for one of the new species.

A new species of Arachnopsita (Orthoptera: Grylloidea: Phalangopsidae) from caves in Guatemala.

The current work presents the description of a new species for the genus Arachnopsita Desutter-Grandcolas Hubbell, 1993 from caves in the municipality of Raxruh, Alta Verapaz, Guatemala. The morphology of the phallic complex was used as the main criterion for distinguishing the species. In addition, we present the additional description for Arachnopsita cavicola (Saussure, 1897) and Arachnopsita uncinata Desutter-Grandcolas, 1997 from a new analyzed material.
