Living in the darkness: a new cave cricket species of the genus Endecous Saussure (Orthoptera, Grylloidea, Phalangopsidae) from Serra da Bodoquena in Mato Grosso do Sul state, Brazil.

We describe a new species of the genus Endecous Saussure (1878), recorded at the Dente de Cão and Urubu Rei caves, which are located in the Bodoquena municipality, state of Mato Grosso do Sul, Brazil. Species of Endecous are the most common of crickets in Brazilian hypogean environments. Endecous comprises 24 species described and is widely distributed throughout South America, occurring also in Argentina, Bolivia and Uruguay. We also present a brief discussion about the presence of the genus in subterranean environments and a distribution map of Endecous troglobitic species through the regions of the Brazilian karst.

Desutterella n. gen., a new genus of Luzarinae (Orthoptera: Grylloidea: Phalangopsidae) and the first report of the Aracambiae group Souza-Dias & Desutter-Grandcolas, 2014 in the Amazon.

A new genus and two new species of Luzarinae cricket (Grylloidea, Phalangopsidae) are described from the Amazon Rainforest of Brazil and Colombia. Desutterella manauara n. gen. n. sp. and D. colombiana n. gen. n. sp. are described based in characters of external morphology and genitalia. The new genus is characterized by the presence of reduced and pubescent male forewings, with stridulatory vein visible but other areas for sound production and propagation absent, and file teeth very reduced, vestigial. Regarding the male genitalia, Desutterella n. gen. presents an extra projection in the pseudepiphallic paramere 2, a condition not observed in the Aracambiae until now. Besides the description, we provide morphological evidence for the glandular nature of the metanotum of males through scanning electron microscopy analysis, a discussion about the morphological and genital features of this new genus, and a distribution map of the Aracambiae group.
