Chorotype.
A typical W-Mediterranean element present in North Africa and Southern Europe.
Italian distribution.
Sardinia
. Not yet recorded from mainland
Italy
nor from
Sicily
.
Ecology.
A vernal species, flight period earlier than that of
D. sardous
sp. nov.
, with a wide ecological amplitude in Southern Europe.
Notes.
The female specimens from SAR1 and S1 do not present the usual wing pattern of
D. antipedalis
. The costal cell is hardly or not yellowish-tinged, thus not contrasting with the rest of the membrane, and the hind veins are only weakly darker than membrane. Accordingly, they are only tentatively attributed to
D. antipedalis
, even if the shared similarities with this species (e.g., shape of head, arrangement of spines on anterior tibia, first antennal flagellomere contrasting yellow, abdomen markedly bicolorous, with tergites much darker than sternites etc.) are numerous.
