Abstract

A new species of Enchytraeidae, Cernosvitoviella tridentina sp.n., is described from alpine streams (Stelvio National Park, Trentino). C. tridentina sp.n. belongs to a group of species with spermathecae confined to the V segment; it particularly resembles Cernosvitoviella carpatica (Cernosvitov), C. minor Dozsa-Farkas and C. celere Nurminen, but differs from these species by some important anatomical features: the presence of small seminal vesicles, longer ectal ducts of the spermathecae and (from two first species) by deep incision of the posterior margin of the brain.
