Labidoculex Reichensperger, 1936 is a Neotropical genus of myrmecophilous rove beetles (Staphylinidae) currently consisting of three described species. The genus has a disjunct distribution extending from Mexico, Bolivia, Brazil, and Argentina, and the species are known to be associated with army ants of the genus Labidus Jurine, 1807. Here, we describe and illustrate a new species within the genus, Labidoculex wazowski sp. nov., based on two individuals collected with a light trap at the Estação Biológica de Boracéia in Brazil. Most of the host association and biology of Labidoculex species remain speculative, since only one species has been collected with ants. However, we suggest that L. wazowski sp. nov. may be a myrmecophilous guest of Labidus, based on the co-occurrence with these ants in the type locality and with other myrmecophilous collected in the same collection. The new species is the first record of the genus Labidoculex for the state of São Paulo, Brazil.
