Body length: 2.76–2.80; body width: 1.32–1.40; length of pronotum: 1.32–1.37, width of pronotum: 1.00–1.05; length of hemelytron: 1.74–1.80; length of discoidal area: 1.35–1.40; length of antennal segments I–IV: 0.13–0.14, 0.08, 0.55, 0.28.

General body brown, abdomen castaneous, legs yellowish-brown.

Head brown, sparsely covered with delicate silvery hairs; head distinctly elongated in front of eyes, apex of clypeus surpassing apex of first antennal segment. Head armed dorsally with two short frontal spines (spines placed closely one another); eyes brown, moderately large, frons 1.6 times broader than width of the eye. Antenniferous tubercles with lateral curved robust outgrowths. Antennal segments I and II brown, very short, bearing long, apically curved hairs.

Bucculae opened anteriorly, their apices rounded, each buccula composed of three to four rows of areolae (bucculae slightly narrowing to apices); sternal laminae uniseriate, subparallel, opened distally; rostrum reaching the posterior margin of third visible abdominal sternite. Orifice indistinct.

Pronotum brown, sparsely covered with delicate, curved brown hairs; pronotal disc flattened, shiny, punctate; triangular pronotal process areolated; pronotal laminae almost parallel, relatively high, uniseriate; anteromedian pronotal cyst small, subglobose, areolated, covering basal half of the head – anterior margin of the cyst reaching between the eyes; paranota slightly upcurved, their lateral margins rounded, each paranotum composed of two to three rows of areolae in its widest part.

Hemelytra sparsely covered with long, curved brown hairs, areolated, its lateral margin slightly rounded; costal area slightly upcurved, composed of one to two rows of areolae, areolae relatively large; subcostal area almost vertical, composed of three rows of areolae; R+M-vein raised; discoidal area slants inwards, composed of four rows of areolae in its widest region; Cu-vein delimiting discoidal area from the sutural area, weakly developed; sutural area reduced, composed of four rows of areolae in its widest part. Hind wings absent.

Legs moderately long, covered with short hairs. Aedeagus with ductus seminis bifurcate distally and apically sclerotized, its wall partially thickened; secondary gonopore and endosomal diverticula paired ( Fig. 2 ).
