ABSTRACT. Trechini is a tribe of Carabidae (Coleoptera) widely distributed in the Andean Patagonian region in South America. In spite of several partial revisions of the tribe for Argentina and Chile, it is very common to find new species due to the research of unexplored areas. In the present paper, a new species of the genus Trechisibus Jeannel from the Cerro Nevado (Mendoza, Argentina) is described. Based on its morphological features the new species is considered as a member of the depressus group. The adult of the new species is described and illustrated, a key for the identification of the species of the depressus group is provided, and some aspects of the distribution of the group are discussed.
