title: Badister Clairville 1806: A new species and new continental record for the nominate subgenus in Amazonian Perú (Coleoptera, Carabidae, Licinini).
abstract: Badister (Badister) amazonussp. n. is described from Perú, Loreto, 1.0 km SW Boca del Rio Samiria, Vigilante Post 1, 130m, "04°40.5'S, 074°18.9'W" its type locality. It is known also from two other localities in Loreto Department, Perú, in both the Varzea and Igapó river systems. This new species is sufficiently different that a new informal higher taxon, the amazonus species complex, is recognized. An updated key to the Western Hemisphere species of subgenus Badister is provided.
