Description. — Male. Body length 5.1 mm; LFW 3.25 mm. Color: head and mesosoma black; metasoma and clypeus dark castaneous; antennae, mandible and legs castaneous; palpi light castaneous; wings subhyaline.
Head: mandible bidentate. Clypeus trapezoidal. First four antennal segments in a ratio of 18:7:6:7, segment XI 1.57 X as long as broad, sensillae conspicuous. Frons strongly coriaceous, punctures shallow, separated by 0.2–1.0 X their diameters. LH 1.02 X WH; WF 0.63 X WH; 1.38 X HE; OOL 1.39 X WOT; DAO 0.34 X WOT; posterior ocelli distant from the vertex crest 1.77 X DAO, frontal angle of ocellar triangle acute. Vertex slightly concave medially, corners rounded. VOL 0.48 X HE.
Mesosoma: thorax coriaceous as frons. Pronotal disc 0.51 X length of mesoscutum. Propodeal disc 0.59 X as long as wide, with small polished area posteriorly. Fore femur 3.3 X as long as thick.
Metasoma: tergite II with pair of elliptical pits, distant each other 6.5 X their length, distant from posterior margin of tergite I 0.88 X their length, closer to the lateral margin than the middle, placed at the inner area of rounded shallow depression (Fig. 72), inner part of each pit covered by translucid sclerite, so that the hole is hemispheric and inclined, from which emerges small tuft of hairs (Fig. 73). Hypopygium with median stalk 1.7 X as long as plate, posterior margin straight. Genitalia (Figs. 74–75): paramere with apex slightly convex and directed inward, dorsal margin straight, ventral margin badly convex; basivolsella dilated and well­differentiated from basiparamere internally; aedeagus with ventral ramus as long as dorsal body, angled medially outward, apical area with four teeth, being the apical one larger; dorsal body with three pairs of apical lobes, outer pair bulging, basal margin concave, angled laterally, apex rounded, ventral margin denticulate and excavated medially (Fig. 76), inner pairs membranous, stout and hairy, being the median pair longer than the ventral one; basal process with two teeth projected outward; apodeme extending beyond the elliptical genital ring.
