FEMALE—Length 7 mm.; black; length of face subequal to distance between eyes; eyes subparallel; cheeks slightly narrower than eyes; process of labrum shining and impunctate, in contrast to the closely and deeply punctate lateral areas of labrum, strongly constricted medially because of the incurved lateral margins, apex truncate; facial foveae narrow and elongate, quite strongly divergent from eye margin above, narrowed below, terminating at level of antennae; distance between lateral ocelli less than that separating ocelli from edge of vertex; median segments of flagellum slightly broader than long; punctures of head coarse and close, those on clypeus below rather shallow, and those on vertex laterally more widely separated; pubescence of head and thorax very short and thin, entirely whitish; tubercles dark; tegulae dark ferruginous; wings whitish basally, becoming lightly infuscated apically, veins reddish, stigma more piceous, 2nd recurrent vein entering 2nd submarginal cell much nearer apex than
1st does to base; legs entirely dark; anterior spurs yellowish, the mid and hind spurs somewhat reddened; dorsum of thorax shining, punctures of scutum very fine and quite close, quite uniform, those on scutellum slightly more coarse and very close, those on pleura much more coarse and quite close except near middle posteriorly where they are well separated but not sparse; apical margins of abdominal terga evenly depressed, smooth, shining and impunctate, slightly reddened, discs of the terga shining, deeply and rather finely punctate, punctures on basal tergum rather widely separated, becoming successively closer on the succeeding segments, discal pubescence extremely short, thin and obscure, becoming rather long and dense toward apex, tergum 5 with a distinct, dark brownish, apical fimbria.
MALE—Length 7 mm.; blackish to piceous; length of face subequal to distance between eyes above; eyes subparallel; face largely dark, clypeus with a median, elongate, yellow spot, and inferior inner orbits very narrowly yellow; cheeks subequal to eyes in width; process of labrum constricted medially due to the incurved lateral margins, apex rather broadly and deeply emarginate; mandibles ferruginous; facial foveae narrow and elongate, quite deep and distinct, slightly divergent from eye margin above; space between lateral ocelli slightly less than that separating them from margin of vertex; median segments of flagellum about as broad as long; head deeply and quite coarsely punctate, punctures rather widely separated on vertex laterally, otherwise quite close even on clypeus below; pubescence of head and thorax very short, thin and obscure, entirely whitish; tubercles slightly reddened; tegulae reddish-hyaline posteriorly, more piceous anteriorly; wings more hyaline basally, becoming slightly infuscated apically, veins testaceous, stigma more brownish, 2nd recurrent vein entering 2nd submarginal cell much nearer apex than 1st does to base; tarsi yellow, femora and tibiae largely dark, but front femora yellow anteriorly, otherwise reddened; spurs yellowish; dorsum of thorax shining, punctures of scutum very fine and quite close, quite uniformly distributed, with a few scattered larger punctures, being thus obscurely doubly punctate, those on scutellum slightly more coarse and close; pleura shining, much more coarsely punctate, the punctures close above, slightly separated posteriorly and below; apical margins of abdominal terga quite evenly and deeply depressed, these areas smooth and shining, impunctate, the discs deeply and distinctly punctate, basal tergum very sparsely so, 2nd and following terga quite closely punctate basally, the punctures becoming more sparse toward apical rim, discal pubescence very short, thin and obscure, entirely pale; apical margin of sternum 6 rather broadly and shallowly emarginate or incurved; wings of sternum 7 quite evenly semi-circular, tips rather narrowly rounded, bearing a few very short setae; process of sternum 8 elongate-triangular, narrowed apically, the tip slightly produced and more narrowly rounded; gonostyli simple, nearly straight, quite strongly compressed and slightly exceeding the rather robust penis valves.
