Description.

Male. Body length 5.0– 5.5 mm, lateral view Fig. 29 View Figures 23–34 . Head black, frons with small yellow spot below anterior ocellus. Mesosoma and metasoma black, pygidium sometimes brownish. Legs black, fore femur with red apex, fore tibia inner side and basally reddish-yellow, fore tarsus reddish-brown. Antenna black, antennomeres IX – XII ventrally pale yellow or pale brownish. Mandible black, reddish mesally. Malar space about 1.2–1.5 × as long as diameter of anterior ocellus. Middle clypeal lobe smooth and shiny, anterior margin roundly protruding, apex bent upwards from lateral lobes separated by deep sulcus. Lateral clypeal lobes with fine transverse striae. Face, frons, vertex and occiput shiny, finely micro-punctate; occiput with white setae (Fig. 31 View Figures 23–34 ). Antennomeres I – III with dark bristles. Mesoscutum, mesoscutellum and mesopleuron smooth and shiny; anterior surface of mesoscutum coriaceous with short white setae. Mesopleuron ventrally with white setae. Propodeal dorsum finely granulate, lateral surface of propodeum coriaceous, declivity smooth and shiny with strong punctures. Propodeum, except dorsum, with white setae. Metasoma shiny, tergum I and sterna with white setae. Mid- and hind coxa with pale setae. Longest ventral setae of fore- and hind femur no longer than half maximal femur diameter. Tegula dark brown. Forewing hyaline, basal sclerites brown and pale yellow, base of veins and subcosta before the pterostigma pale yellow, other veins and pterostigma dark brown. Anterior margin of marginal cell about 1.2–1.8 × as long as apical height (Fig. 7 View Figures 1–16 ).

Female. Body length (4.5) 5.5–6.5 mm, lateral view Fig. 30 View Figures 23–34 ). Head, antenna and mesosoma black. Mandible reddish-brown with black tip. Metasoma black, terga I – II sometimes dark brownish, pygidial plate reddish. Coxae, trochanters and femora black; fore tibia reddish-brown; mid and hind tibia dark brown; fore- and mid-tarsus reddish, hind tarsus dark brown. Malar space about 0.3–0.5 × as long as diameter of anterior ocellus. Middle clypeal lobe shiny with some punctures, anterior margin with two very small teeth (Fig. 14 View Figures 1–16 ). Face and frons very finely micro-reticulated, with very scattered distinct punctures (Fig. 32 View Figures 23–34 ). Vertex and occiput smooth and shiny, the latter with short white setae. Antennomeres I – III with black bristles. Pronotal collar micro-reticulated, with short white setae. Mesoscutum smooth and shiny, anterior margin coriaceous, with short white setae. Mesoscutellum smooth and shiny, finely micro-striated posteriorly. Mesopleuron micro-reticulated, moderately shiny, ventrally with brownish setae. Epimeron smooth and shiny, distinctly different from remaining parts of mesopleuron. Propodeal dorsum densely granulated, dull. Lateral surface of propodeum coriaceous, dull, with longitudinal striae posteriorly. Declivity coriaceous with some stronger punctures. Propodeum, except dorsum, with white setae. Metasomal terga finely micro-striated. Sternum II and posterior margins of following sterna with black setae. Fore basitarsus with four black rake spines, apical spine about as long as fore tarsomere II. Fore- and hind femur with black setae ventrally; the longest ones of fore femur about half as long, those of hind femur about two thirds as long as maximal femur diameter. Coxa and trochanter of mid- and hind legs with black bristles. Tegula brown, posterior margin transparent. Forewing hyaline, basal sclerites, base of costa and subcosta pale yellow, subcosta before pterostigma pale brown; other veins dark brown, pterostigma brown. Anterior margin of marginal cell about 0.9–1.2 × as long as apical height (Fig. 8 View Figures 1–16 ).
