Ocorrência do Grilo Endecous em Quatro Cavernas no Município de Uruará - PA, Brasil

Abstract

Resumo. O gênero Endecous

Endecous apterus: A new species of cave cricket from northeast Brazil, with comments on the use of subterranean habitats by Luzarinae crickets (Orthoptera: Grylloidea: Phalangopsidae: Luzarinae)

“…In Brazil, it occurs in all biomes and is the most conspicuous and widespread genus of cricket in hypogean environments. Endecous populations have been reported to occur in many cavities, in almost all of the main Brazilian karst areas, particularly in the southern, southeastern, and central states, and also in some northern and northeastern states, such as Pará, Maranhão, Ceará, Rio Grande do Norte, and Bahia (Trajano, 1987;Trajano & Gnaspini-Netto, 1991;Pinto da Rocha, 1993;Pinto da Rocha, 1995;Trajano, 2000;Zeppelini-Filho et al, 2003;Ferreira et al, 2010;Trajano & Bichuette, 2010;Silva et al, 2011;Cajaiba, 2012). To date, however, only four species have been described from cave populations: E. alejomesai Zefa, 2010; E. betariensis de Mello & Pellegatti-Franco, 1998;E.…”

First record of a phoretic mite (Histiostomatidae) on a cave dwelling cricket (Phalangopsidae) from Brazil

“…In the case of some mites, such as the histiostomatid, the unfavorable environmental conditions (such as drying out, overcrowding, lack of food, and accumulation of waste products) favor the interposition of the hypopus stage, which is adapted to dispersion by a host (Binns, 1982;Knülle, 2003;Reynolds et al, 2014). However, it is important to highlight that even considering caves as suitable habitats for mites and crickets, it is possible that this is a sporadic and rare interaction given the number of crickets observed without mites during the studies regarding Brazilian cave fauna in the last years (Cajaiba, 2012;Souza-Dias et al, 2014;Bolfarini and Bichuette, 2015;Castro-Souza et al, 2017;Cigliano et al, 2017).…”
