Abstract

The freshwater crab Trichodactylus fluviatilis Latreille, 1828 is recorded here for the first time, at an altitude above 1000 m a.s.l. Sampling was performed in the Grota stream in Campos das Vertentes, Minas Gerais state, Brazil. This new record extends the known altitudinal distribution to 1115 m a.s.l., which significantly contributes to understanding the conditioning limits and factors for this species’ distribution. Moreover, the occurrence of an ectosymbiont platyhelminth of the genus Temnocephala is also reported on the crabs collected.
