Description Holotype ♂ ( Fig. 4A ). Body length 5.1 mm. LFW 3.7 mm.

COLOR. Head and mesosoma black, except pronotal collar and posterior end of pronotal disc dark castaneous; metasoma dark castaneous; antenna castaneous with flagellomeres progressively darker distad, palpi light castaneous; mandible and tegula castaneous; legs castaneous with coxae darker; wing membrane subhyaline, veins castaneous.

HEAD. ( Fig. 4B ). Mandible with one lower large tooth and upper cutting edge ( Fig. 4C ). Clypeus projecting forward subangulate median lobe, its length 0.19x LH; median carina conspicuous, slightly high and arched in profile. Antenna 1.95 mm long, reaching posterior end of pronotum; scape arched, widened distad; pubescence suberect with some erect setae. First four antennomeres in ratio of ~23:6:11:11; segment XI 2.25x as long as wide. Eye with sparse short hairs. Frons polished, shining, punctures small, somewhat deep, separated each other by 1.0-3.0x their diameters. Frontal groove absent. LH 1.14x WH; WF 0.52x WH; WF 1.0x HE; frontal angle of ocellar triangle acute; WOT 3.3x DAO, OOL 1.2x WOT; DAO 0.16x WF; posterior ocellus distant from vertex crest 2.3x DAO; anterior margin of anterior ocellus not reaching imaginary top eye line. Profile of vertex crest convex in dorsal view; corner rounded; VOL 0.49x HE. Temple profiles diverging anterad in dorsal view. Occipital carina not visible in dorsal view.

MESOSOMA. ( Fig. 4 D-F). Thorax dorsum shinning, punctures smaller and sparser than those of frons. Pronotal disc trapezoidal; side straight in dorsal view; anterior margin slightly convex, not carinate, pronotal declivity vertical. Notaulus conspicuous, slightly arched, complete anteriorly, convergent posterad, gradually wider posteriorly, not reaching posterior margin of mesoscutum. Parapsidal furrow incomplete anteriorly, conspicuous, slightly arched. Region around parapsidal furrow bulging. Scutellar groove deep, narrow, arched, slightly dilated laterally. Metanotum with median elevation; median fovea semi-circular; metanotal groove foveolate laterally, first fovea large and triangular, not punctured inside, others rectangular and narrower than first one. Propodeal disc 0.64x as long as wide, median carina complete, disc rugulose; spiracle short, elliptical, completely placed at lateral of propodeum, lateral carina abruptly curved anteriorly to accommodate spiracle; posterior carina little distinguishable. Propodeum strigulate laterally. Declivity of propodeum coarsely rugulose, without median carina, almost straight in lateral view. Mesopleuron with subtegular groove dilated anteriorly and evenly narrow posteriorly, foveolate inside; episternal groove not continuous to subtegular one, foveolate; mesopleural callus polished and shinning; anterior region strongly punctuate to puncticulate posteriorly ( Fig. 4E ). Pleurosternum mostly polished, acetabular carina wide posterior pit deep ( Fig. 4F ). Fore femur 3.4x as long as wide. Tarsal claws bidentate, teeth sharp.

WINGS. ( Fig. 5 ). Forewing with radial vein long and evenly curved; R 1 short than half length of stigma; M+Rs (basal vein of Evans) concave; cu-a (transverse vein of Evans) angulate; Cu a (discoidal vein of Evans) tubular for short distant, intersecting M+Rs. Hind wing without basal hamuli, with six equidistant median hamuli.

METASOMA. ( Fig. 6 A-B). Not petiolate; anterior half mostly polished, posterior half mostly very weakly coriaceous; progressively more hairy posterad. Sternite VII rectangular, without median stalk, lateral stalk very short, posterior margin with median narrow semicircular concavity. Hypopygium ( Fig. 6 A- B) strongly concave, but not divided into two lobes, inner margin badly concave, inner surface setose apically, median stalk about 0.6x as long as plate, lateral stalk very short, dorsal surface short, surrounding inner margin of lobe, progressively higher basad, posterior margin with perpendicular median lamina directed upward.

GENITALIA. ( Fig. 6 C-D): paramere subvertical, about as long as basiparamere; placed dorsally, outer surface mostly hairy, bilaminar, except basal-inner quadrant; apex rounded; wide, dorsal margin much developed mesad, especially basally, basal half convex, apical half concave, with median angulate callus; ventral margin straight. Basiparamere with dorsal margin inclined and truncate in lateral view. Basivolsella completely outlined and separated from basiparamere, short, basal half subquadrate. Digitus laminar, wide, rounded, dorsal surface convex and denticulate. Cuspis laminar, base completely angled upward, somewhat narrow, apex rounded. Aedeagus bulging, divided into dorsal and ventral parts, apex of dorsal one with three pair lobes, dorsal lobe completely angled ventrad, tubular, apex deeply bifurcated; median lobe stout, apical margin with delicate filament apicad, ventral margin denticulate, inner margin membranous and little hairy, ventral lobe with large expansion directed downward; ventral surface laminar expansion, angled laterad with apex rounded and base with ventral loop of irregular margin; ventral part of aedeagus laminar with base wider than apex, inner surface vertical, inner lower part with ridge, apex divergent. Genital ring subrectangular. Basal ring narrow. Apodeme narrow, extending beyond genital ring.
