Pseudolycoriella angustoantennata
sp. n.
(Fig. 1 A–C)
Description
. Male.
Head:
Ovoid, mouth parts weakly elongate; eye bridge 4 facets wide; antennae short, brown; 4
th
flagellomere with l/w index of 1.2, with short neck, surface somewhat rough, some fine sensilla inserted in deeper pits, hairs as long as half of the diameter of the basal node; palpus 3-segmented; basal segment with 5–6 bristles and a patch of short sensilla.
Thorax:
Brown; scutum with short dorsocentral and a few stronger lateral hairs; scutellum with 2 longer posterior hairs; postpronotum bare. Wings pale, with distinct veins; R
1
= 2/3 R; R
5
with dorsal macrotrichia only; C = 3/4 w; y = x, bare; Cu-stem rather short; posterior wing veins without macrotrichia. Halteres short, with darkened knobs; legs brownish; fore tibiae at the inner apex with a row-like patch of bristles, not bordered; spurs of middle and hind tibiae of the same size, brownish, as long as the diameter of the tibia apex; claws finely toothed.
Abdomen:
Tergal and sternal hairs sparse and moderately short; hypopygium brown, gonocoxites ventrally and along the inner ventral margins with short sparse hairs; gonostylus elongate and ovoid, apically broad rounded, with two rather long spines of the same size and a longer whip-lash hair; tegmen wider than long, apically rounded; aedeagus rather long, with large basal furca. Body length:
2.2 mm
.
Comments
. The species is similar to
Psl.
fuscovenosa
sp. n.
and
Psl. cavatica
(Skuse, 1888). It differs from the first species mainly by having longer apical spines on the gonostylus and much shorter antennal flagellomeres. Like
Psl. cavatica
it has similar short flagellomeres but differs in the shape of the gonostylus, by having longer apical spines, a less sclerotized tegmen and a longer aedeagus. The species belongs to the
Psl. longicostalis
group sensu Mohrig (2013).
