Abstract - A new Duvalius Delarouzée, 1859 from central Umbria (Coleoptera, Carabidae) - A new anophthalmic, unpigmented species - Duvalius gallii - has been found in an abandoned iron quarry in Umbria (C Italy). This horizontal quarry (Grotta della Miniera, N° 106 U/Pg, Monte Penna, Cava del Ferro, Gualdo Tadino, Perugia) is crossed by many pits which are very likely inhabited by the species. Duvalius gallii has a membranous copulatory piece in direct contact with the internal sac, typical of species belonging to the bensae group (sensu MAGRINI, 1997, 1998), without a median unequal process and apically more sclerified. The copulatory piece has a faintly separated bifid apex with two small projections which appear rounded when viewed ventrally and pointed when viewed laterally. The aedeagus is long and sinuate with an apical button facing upward. The shape of both the aedeagus and its copulatory piece place this new taxon on a species level, as detailed in the images accompanying the text.
