Telegeusinae is a small subfamily of Elateroid beetles presently attached to the Omethidae family. Pseudotelegeusis Wittmer, 1976 is composed of three species, two occurring in northern South America and one in Mexico. Here we describe the fourth species for the genus, Pseudotelegeusis meloi sp. nov., collected in a Malaise sample from the region of Madre de Dios, Peru. The new species is diagnosed mainly by the antennae serrate from antennomeres III to X, eyes occupying half of head width in lateral view and vertex occupying 3/5 of head in dorsal view. This new species is close to the other two South American species, P. howdeni Wittmer, 1976 and P. oculatus Wittmer, 1976, according to the serrate antennae and number of ventrites. The three South American species differ from the Mexican species, P. jiliotupaensis Zaragoza-Caballero, 2008, by the different antennae and the number of ventrites, which indicates that the Mexican species should possibly be classified in a different genus. The main morphological characters, including maxillar palpi, tentorial pits and male genitalia, are illustrated, and an updated key to the species of Pseudotelegeusis is given, as well as distribution maps.
