Abstract

Cryptolestes obesus Thomas, 2002 (Coleoptera: Laemophloeidae) was described based on a single female specimen collected in Rondônia state, Brazil. As previously hypothesized, the robust body shape and the presence of complete secondary sublateral lines on the pronotum are diagnostic for C. obesus and fundamental traits for male association. Here we associate and describe the conspecific male, with a new record of this species for Santa Catarina state, Brazil. The habitus, antennal scape, and genitalia of the male are illustrated.
