The first record of Adelosgryllus Mesa amp; Zefa, 2004 (Orthoptera: Grylloidea: Phalangopsidae) from caves, with the description of a new species from Brazil.

The first species for the genus Adelosgryllus Mesa Zefa, 2004 recorded in caves is herein described. We used the morphology of the phallic complex as the main criteria to differentiate this species from the congeneric ones. In addition, we discussed the natural history of the new species, some aspects of its association to the cave habitats, and the intraspecific variation of the right tegmen observed in two populations of this new species.
