Ocellar triangle broad, silver pruinose, with convex margins and reaching lunule.Male fronto-orbital plate and parafacial almost bare.Antenna dark brown; postpedicel very short. Arista short, dark brown; bare on apical third. Palpus yellow, abruptly dilated in the apical portion which is densely silver pruinose. Vibrissa absent. Thorax. Scutum grey dusted. Dorsocentrals 2+3. Lower katepisternal strong, forming an equilateral triangle with the upper two setae. Haltere yellow. Calypters white. Legs. Brown, grey dusted; tarsi yellowish brown. Fore tibia with 1 posterior median seta. Mid femur with 1 posterior preapical seta. Mid tibia with 1 median posterior to posterodorsal seta; without anterodorsal and anteroventral setae. Hind tibia with 1 median anteroventral seta; without anterodorsal and posterodorsal setae; 1 long dorsal in apical fourth; 1 preapical anterodorsal. Hind tarsomere 1 enlarged and setulose.

Remarks. The species can be recognized by the broad and silver pruinose ocellar triangle; very short antenna; absence of vibrissa; palpus densely silver pruinose at apex; and hind tarsomere 1 enlarged and setulose. It can be identified with the key by Hennig (1960) to Palaearctic
Lispe
. The hind tarsomere 1 was illustrated by Hennig (1960, text-fig. 97). It belongs to the
caesia
-group of
Lispe
(Hennig 1960)
