Abstract - Two new Duvalius Delarouzée from the Ligurian Apennines and further notes on the species of Duvalius of the doderii group (Coleoptera Carabidae Trechinae) - The Author reports the results of long personal hypogean researches on the Ligurian Apennines north-east to Genoa, on the Duvalius of the doderii species group [in the restricted sense of “lignée du Duvalius doderoi” by MAGRINI (1997, 1998), and in the broader sense of “brucki group” by VIGNA TAGLIANTI (1970, 1982)]. Two new taxa belonging to this group are described: D. ramorinii radicis n. subsp., from a cave near Mt. Antola (Liguria, Brevenna Valley, GE, Carsi, “Tann-a da Reìxe” cave, n° 132 Li/GE m 875 a.s.l.), and D. alexandrinus n. sp. from Mt. Chiappo (Piedmont, Curone Valley, AL, Bruggi, m 1200 a.s.l.). Within the same group, together with D. ramorinii ramorinii (Gestro, 1887) and D. pastorellii Casale & Magrini, 2013, the new taxa represent a monophyletic and very homogeneous unit - besides the other two, more isolated and monospecific, D. doderii (Gestro, 1885) and D. gestroi (Dodero, 1900) - to be assigned to a new, separate subgroup. Moreover, new data and comments about the taxonomy and geographic distribution of Duvalius gestroi s.l. are provided.
