Item A new troglophilic species of Erebonyx (Orthoptera: Grylloidea: Phalangopsidae) from Brazilian caves(2022-12-16) Merlo, Rayanne Lays Sant'ana ; Castro-Souza, Rodrigo Antônio ; Bento, Diego de Medeiros ; Ferreira, Rodrigo LopesThe genus Erebonyx was proposed to accommodate a single troglobitic species from northeastern Brazil. A second cricket belonging to this genus is herein described, but although it was also found in caves, it does not bear any troglomorphic traits, suggesting it is a troglophilic species. The new species differs from the other species on the genus in the phallic sclerites, presence of developed eyes (with ommatidia), pigmented integument, and the presence of stridulatory file on the tegmina. In addition, we present the description of the external morphology, together with the staining and description of tegmina. Finally, we present a brief discussion regarding its habitat, distribution and possible conservation actions for the species.Item Expanding the taxonomic knowledge of Adelosgryllus Mesa & Zefa, 2004 (Orthoptera: Grylloidea: Phalangopsidae): description of four new species for Brazilian subterranean habitats(2022-05-03) Merlo, Rayanne Lays Sant'ana; Castro-Souza, Rodrigo Antônio ; Junta, Vitor Gabriel Pereira ; Ferreira, Rodrigo LopesIn this study, four new Brazilian species are described for the genus Adelosgryllus Mesa & Zefa, 2004, occurring in Minas Gerais, Tocantins and Pará 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. Finally, we bring a brief discussion about the ecology, distribution, and conservation of these species.
