    • Abstract:
      La tribu Metiini (Coleoptera: Carabidae) es endémica de América del Sur, distribuida principalmente en su región austral en Argentina y Chile, pero también llegando a Uruguay y en los Andes hasta Perú y Bolivia. Se conocen cuatro géneros, de los cuales Metius Dejean es el más diverso. El análisis de la morfología de una de sus especies, Metius crassiusculus Putzeys, revela que la misma no debe ser incluida en este género, y que tampoco puede serlo en los restantes géneros de la tribu, por lo que se propone el nuevo género Selknam gen. nov. Se provee una descripción y una clave dicotómica para separarlo de los restantes. También se consideran algunos aspectos del ambiente costero donde habita S. crassiusculus. [ABSTRACT FROM AUTHOR]
    • Abstract:
      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.
