Chorotype. Mediterranean: from the east coast of the Black Sea to Portugal ( Liberti 2004a). In Italy it can be found along the Tyrrhenian coast from Liguria to Sicily and in several of the neighbouring Tyrrhenian islands ( Liberti 2004a). Affinities: rather close to D. (M.) iteratus and D. (M.) croceipes , which have a smaller range.

Notes. Reported by Schilsky (1895), Bertolini (1899 –1904) and Sainte-Claire Deville (1908) for Sardinia, where it is uncommon and is usually collected in just a few specimens. It can be easily differentiated from the other Mesodasytes by the colour of legs and antennae.
