Middle clypeal lobe slightly protruding, wider than long, anterior margin straight. Occiput shiny with very shallow and dense punctures and long and dense whitish pilosity. Antenna. Black. Antennomere I with white setae on inner surface, III about 4 × as long as apically wide; V-X slightly concave to straight in profile, maximum width in the distal third (Fig. 27 ). Tyloids with hardly lightened tubercles proximally and distally. Thorax. Black, with white setae. Tegula black. Pronotal collar dull, densely punctate, punctures sometimes confluent into striae. Anterior surface of mesoscutum moderately shiny, densely punctate; posterior surface with scattered punctures and shiny. Mesoscutellum smooth and shiny, closely punctate laterally and distally. Mesopleuron shiny and moderately dense punctate. Wings. Hyaline. Basal sclerite and veins dark brown, pterostigma pale brown. Marginal cell about 3.5 × as long as maximal width. Legs. Coxae and trochanters black with white setae. Femora black with red tips; tibiae and tarsi red. All femora with white setae. Midcoxa on inner surface rounded, hindcoxa and -trochanter without special characters. Propodeum. Black. Dorsal surface glabrous, reticulate. Lateral and posterior surfaces dull, punctate-rugose, with white pubescence. Metasoma. Segments I-III and anterior surface of IV black, posterior surface of IV and V-VII pale ferruginous. Tergum I dull, rugose, with shallow punctures, the following terga microscopically reticulate and slightly shiny. Tergum I and sterna with long white setae. Metasomal hairbrush well developed, whitish, inner setae very short and appressed, lateral setae distinctly longer than those on sternum II.

Description female

(after Turner 1917a and Arnold 1923). Habitus. Body length 8 mm. Head. Black. Mandible reddish with black apex. Middle clypeal lobe very short, apical lamella straight. Frons with stiff black bristles. Upper half of face, vertex and narrow border on inner orbits shiny, with coarse and scattered punctures. Occiput with greyish setae. Antenna. Black. Antennomere I reddish. Thorax. Black. Tegula brown. Pronotal collar finely punctate. Mesoscutum shiny, anterior third densely punctate with stiff black bristles intermixed with white setae, posterior surface nearly impunctate, at most with some large punctures.

Forewing with brownish tinge, veins and stigma yellowish-brown. Marginal cell of forewing short, anterior margin about as long as height. Legs. Femora black, tibiae and tarsi brown. Femora with black setae. Propodeum. Black. Dorsal surface glabrous, reticulate. Lateral surface smooth in the anterior half, irregularly striated posteriorly. Posterior surface reticulate. Metasoma.
