Un nuevo género de Metiini (Coleoptera: Carabidae) de la región austral de América del Sur.

The tribe Metiini (Coleoptera: Carabidae) is endemic to southern South America, in Argentina, Chile, Uruguay, and in the high Andes of Peru and Bolivia. The tribe comprises five genera, being Metius Dejean the most diverse in species. The study of one of its species, Metius crassiusculus Putzeys, reveals that it is not cogeneric with the remaining of the genus, and presents some exclusive characters and combination of other characters not present in any of the other Metiini genera. Thus, the new genus Selknam is proposed to include it. Description and a key to the genera of Metiini are provided. Some aspects of the coastal habitat where S. crassiusculus was found are discussed.
