Chorotype. Central Mediterranean, present in the south of Corsica, Sardinia and North Africa (but not in Sicily) ( Liberti 2004a: 292). Affinities: it is the Sardinian representative of a small group of species from North Africa, characterized by the robust tooth on the median male trochanter; the similar D. metallicus ( Fabricius, 1792) is common in Sicily ( Liberti 2004a: 291).

Notes. This species is immediatly recognizable (see also D. aeneiventris below) by its entirely black colour, rather large size and very transverse pronotum. Very common in spring all over the island, on flowers in meadows.
