Head. Frontovertex with fairly regular polygonal reticulate sculpture; eyes clothed in very fine, inconspicuous setae and slightly overreaching occipital margin which is sharp; ocelli forming acute angle about 70°; scrobe deep; torulus located midway between lowest eye margin and clypeus, separated from each other by about 1.5× own diameter; antenna with scape cylindrical, about 3.6× as long as broad; pedicel subtriangular, 2× as long as broad; funiculars transverse, F1–F4 subequal in length, F2–F4 subequal in width, F5–F6 gradually broader, ratio of width and length of each segment: 1.5, 2, 2, 2, 1.7, 2; clava 3-segmented, about as long as F1–F6 combined, wider than F6, apex with short slightly oblique truncation (Fig. 22); mandible with three acute teeth (Fig. 24); maxillary and labial palpi 4- and 3-segmented respectively (Fig. 23).

Mesosoma. Pronotum and mesonotum clothed with sparse black setae, with shallow imbricate-reticulate sculpture except apex of scutellum smooth, with 2 or 3 long setae; mesopleuron more or less enlarged but not reaching metasoma so that metapleuron not visible laterally and propodeum slightly separated from base of hind coxa; fore wing (Fig. 25) about 2.5× as long as wide; costal cell with more than one line of setae dorsally; linea calva more or less closed by a single line of setae dorsally; marginal vein about as long as stigmal vein; postmarginal vein about four-fifths as long as marginal vein.

Metasoma. Longer than mesosoma; hypopygium reaching slightly more than two-thirds length of metasoma; ovipositor clearly exserted (Fig. 30), relative proportion of OL and MT: 63:35.
