Diagnoses and key for the larvae of Progomphus Selys, 1854 from Argentina (Anisoptera: Gomphidae), with first larval descriptions for P. aberrans Belle, 1973 and P. kimminsi Belle, 1973

Abstract

Ten species of Progomphus Selys, 1854 are known to occur in Argentina. The larval stages of only four of them aredescribed. We here add the larval descriptions of two species: P. aberrans Belle, 1973 and P. kimminsi Belle, 1973, anddiagnose and illustrate important characters for the remaining species known at the larval stage in Argentina: P. complicatusSelys, 1854, P. joergenseni Ris, 1908, P. lepidus Ris, 1911 and P. phyllochromus Ris, 1918. New geographical records forthese species are presented, including new records for P. kimminsi in Bolivia, and new provincial records in Argentina: P.aberrans and P. joergenseni in San Luis, and P. kimminsi in Santiago del Estero. A key to distinguish the larval stage ofArgentinean species is proposed.
