Abstract

Abstract Austrolimnius cleidecostae sp. nov. is one of the smallest species of Elmidae from the Neotropical region. The new species is described and illustrated based on male and female specimens. This species represents the first record in Elmidae of mandibles with an articulated, sclerotized process on inner subapical edge. The specimens were collected from streams in the Atlantic rainforest of São Paulo and Santa Catarina, and habitat notes are given. An updated key for the AustrolimniusCarter & Zeck, 1929 of Brazil is provided. Austrolimnis browniHinton, 1971 and A. musgraveiHinton, 1939 are recorded for the first time from Brazil. (AU)
