Cricket species of the genus Endecous (Family Phalangopsidae) are widely distributed and highly abundant in Brazilian caves (Ferreira and Martins 1999), with occurrence records in many cavities (Souza-Dias et al. 2014). Souza-Dias et al. (2014) emphasized that this genus occurs in all Brazilian biomes and in subterranean environments, and among cricket genera, it is the most conspicuous and widespread. According to Ferreira (2005), species of Endecous are troglophiles, specialized to the cave environment, and Souza-Dias et al. (2014) state that these crickets inhabit the entrance and the dark zones in caves. Eidmanacris (Family Phalangopsidae) also occurs in Brazilian caves (Pinto-da-Rocha 1995), but its occurrence in caves is still poorly known (Bolfarini 2016). This genus has straminicolous and cavicolous habits, and in the later, species of this genus use natural caves for refuge (Desutter-Grandcolas 1995). According to Souza-Dias et al.
