FEMALE—Length 9 mm.; eyes strongly convergent below; malar space linear, hardly evident; facial foveae shining, broad medially, narrowed above and below; length and breadth of flagellar segments equal; clypeus bare, shining, closely and finely punctate; pubescence pale ochraceous throughout, entirely so on head and thorax; prothoracic angles not spinose; metapleural protuberance strongly mate, margin of the carina testaceous; tegulae dark ferruginous; wings subhyaline, veins and stigma ferruginous; punctures of scutum deep and distinct, close anteriorly, becoming sparse in center of posterior half; scutellum shining and impunctate along anterior border, otherwise closely and coarsely punctate; pleura very closely and deeply punctate; dorsal area of propodeum narrow, with shining quadrangular pits formed by the well separated striae; triangular area of posterior face and bare, lateral areas more dull reticulate, with long thin pubescence; front coxae spined; hind basitarsi slender, elongate; spurs pale ferruginous or yellowish; punctures of abdominal terga minute, close 2nd and following segments, more distinctly separated on 1st medially; hind margins abdominal terga narrowly ferruginous, with broad, dense, apical fasciae, discs very thinly tomentose and appearing dark; apical segment dark.

MALE—Length 7-8 mm.; eyes strongly convergent below; length of malar space about one-fourth its width; facial foveae shallow, barely evident, width of median antennal two-thirds their length; clypeus shining between fine and close punctures, largely hidden by pubescence; pubescence pale ochracous throughout, entirely so on head and thorax; prothoracic angles not spinose; metapleural protuberance strongly carinate, margin of the carina testaceous; tegulae pale wings subhyaline, veins and stigma ferruginous; punctures close and deep on sparse in center of disc and on anterior half of scutellum, close and coarse on scutellum posteriorly; pleura shining below, deeply punctate, the punctures well separated becoming crowded above; dorsal area of propodeum shining between distinct but irregular striae; spurs and tarsal segments pale, ferruginous or testaceous; basitarsi slender, elongate; basal abdominal terga finely but punctate, closely so on the 2nd and only slightly separated in center of disc of 1st; abdominal fasciae entire, quite broad, pale ochraceous; integument beneath ferruginous-hyaline.
