Augusto Siri, Yngve Brodin

Abstract


A new species, Rheochlus latisetus sp. nov., is described from male and female adults from Argentina. Emendations and illustrations of the three previously known species of Rheochlus Brundin, 1966 are provided. A cladistic analysis of the genus Rheochlus within the tribe Podonomini is presented, and the phylogenetic relationship with congeners is discussed based on adult characters.
