MALE—Length 10 mm.; length of face slightly exceeding its greatest width; eyes subparallel, only very slightly convergent below; length of na1ar space about one-third its breadth; antennae dark, median segments twice as bag as broad; clypeus very finely and densely punctate beneath the pubescence; pubescence greyish-white, slightly yellowish on dorsum of head and thorax, without dark admixture; lateral angles of prothorax acute, but not spine-like; metapleural protuberance with a very low obscure carina; tegulae dark; wings subhyaline, very slightly violaceous, veins and stigma ferruginous; 2nd submarginal cell considerably shorter than 3rd; scutum somewhat shining, punctures fine but distinct, separated by two or three times the puncture width over anterior portion of disc. becoming somewhat more sparse posteriorly; anterior margin of scutellum impunctate, otherwise the punctures more course, close and deep than on scutum; posterior portion of pleura with shallow, distinctly separated punctate, interspaces shining, but surface dull, tessellate and very obscurely punctate anteriorly and above; striae of dorsal face of propodeum parallel and quite close; legs dark, basitarsi slender and parallel-sided, length of hind basitarsi about four times the breadth; spurs yellowish-ferruginous ; abdominal terga somewhat shining between the minute, well separated punctures, apical margins slightly depressed, paler in color beneath the entire narrow, white, apical fasciae; discal pubescence fuscous, short and erect on abdominal terga beyond the 1st.
