Abstract
Erebonyx catacumbae, new genus and species of a troglobitic phalangopsid cricket are described from Brazil. Few specimens were collected from a limestone cave located in the municipality of Campo Formoso, northern State of Bahia, in a semi-arid zone characterized by the Caatinga vegetation. A brief discussion on troglomorphisms is provided, as well as some ecological remarks and potential threats for this species.
