(Coleoptera Carabidae Trechinae)

RICCARDO MONGUZZI
Abstract - Trechus sessitanus n. sp. from the Pennine Alps (Monte Barone and Cima delle Balme, Piedmont, Italy) is described. In the very numerous genus Trechus it is an enigmatical and isolated species for its peculiar aedeagus and other distinctive characters. For some characteristics however it seems to be related to Trechus laevipes Putz. (M. Generoso, Lombardy, Italy), which has been ascribed till now to the pertyi-group, but probably it is more isolated.
