Abstract

Chondrodesmus mamirauaensis n.sp. is described from Mamirauá Sustainable Development Reserve, environs of Tefé, Amazonia, Brazil, with first ecological data given. The new species comes closest, both structurally and geographically, to Ch. mimus CHAMBERLIN, 1941, known from a single female (holotype) from Iquitos, Peru, but differs clearly at least by the much smaller body size (width up to 7.5 versus 13 mm) and the pallid versus brown epiproct. This is not only the first formal record of both the genus Chondrodesmus SILVESTRI, 1897 and the tribe Chondrodesmini in Brazil, but also the first representative of the entire family Chelodesmidae showing Vertical migrations in response to annual inundation in the Central Amazonian várzea forests.
