Description.
Male.
Head.
Dark brown. Eye bridge 3 facets wide. Antenna brown; 4th flagellomere with l/w index of 2.2, hairs erect, as long as the diameter of the basal node; neck brown. Palpus brownish, 3-segmented, basal segment with 4–5 bristles, without a deepened sensory area.
Thorax.
Brown. Scutum with whitish hairs, some lateral and prescutellar bristles longer. Postpronotum bare. Wing brownish, R1 = 1/2 R; R5 without ventral macrotrichia; C = 2/3 w; y = x, without macrotrichia; posterior wing veins without macrotrichia. Haltere brownish. Coxae and legs brown; apex of fore tibia with a wide, slightly arched comb-like row of bristles; spurs of middle and hind tibia equal in size, slightly longer than the diameter of the apex; claws without teeth.
Abdomen.
Brown, with fine and sparse whitish hairs. Gonocoxites with dense hairs at the basal third of the inner ventral margin; gonostylus rather short and compact, the apex widely rounded, with short and dense hairs and a long subapical whiplash hair (distinct spines are not visible between the hairs). Tegmen deformed. Body length:
3.5 mm
.
Comments.
This large and dark species is characterized by the whitish body hair, dense hairs at the basal third of the ventral inner side of the gonocoxites, a strong gonostylus with dense hairs at the apex, a long subapical whiplash hair and no spines among the hairs at the apex. It is similar to
Psl.
capillosa
Vilkamaa, Hippa & Mohrig. It
differs by having longer flagellomeres, whitish body hairs, a shorter and more robust gonostylus, different shape of the tibial organ and a longer y.
