FEMALE. — Length about 10mm; occipito clypeal distance (the distance between the highest point on the vertex and the middle of apex of the clypeus) greater than the ocular distance (the distance between the outermost point of each eye), facial fovea extending below the antennal line (an imaginary straight line drawn tangent to the lowest point in the edge of each antennal fossa), the former with its greatest width greater than two-thirds of the shortest distance between the lateral ocellus and nearest eye, third joint of antennae longer than fourth, plus fifth, but shorter than fourth, plus fifth, plus sixth, clypeus punctured, polished, with a median longitudinal impunctate area, process of labrum broadly rounded; abdomen with the second dorsal segment depressed less than one-half the distance between base and apex of the same segment, abdomen fasciate. Tegment almost throughout black or very dark brown in color, most of the hairs pale ochreous, the great majority of the hairs of the tibial scopa not branched but simple.

FEMALE — Length 9 mm.; face slightly longer than broad; clypeus broadly convex, somewhat protuberant, projecting slightly more than one-half below suborbital line, smooth and shining, punctures moderately coarse and deep, well separated on each side of an indistinct, median line; facial foveae quite broad, occupying above most of area between eyes and ocelli, covered with pale ochraceous tomentum; space between margin of vertex and lateral ocelli subequal to their diameter; cheeks broader than eyes, rounded posteriorly, somewhat shining, punctures minute, well separated below, becoming quite close above; length of malar space equal to about one-third basal width of mandible; basal segment of flagellum subequal to 2nd and 3rd combined; process of labrum triangular, with narrowly rounded apex; mandibles rather elongate with a small, inner, subapical tooth located about one-fourth of its length from apex, not noticeably dilated beneath toward base, overlapping about one-third; pubescence of head, thorax and legs pale ochraceous; thoracic integument dull, tessellate, punctures of scutum shallow and rather indistinct, quite close anteriorly, becoming rather sparse in center posteriorly where surface is more shining, and scutellum shining with punctures more distinct but quite irregular, rather sparse; pleura with vague, shallow and rather sparse punctures anteriorly, these becoming inevident posteriorly; dorsal area of propodeum nearly vertical, triangle finely substriate along basal margin; propodeal corbicula rather short, pale ochraceous, anterior fringe poorly developed; trochanteral floccus quite well developed, pale ochraceous; hind tibiae narrow and elongate, apex only slightly broader than basitarsi, scopa rather thin, hairs somewhat elongate, entirely simple, pale ochraceous; front and mid basitarsi slightly narrower than their respective tibiae; 2nd submarginal cell somewhat shorter than 3rd, receiving 1st recurrent about one-third from apex; abdominal terga rather dull, microscopically tessellate, punctures exceedingly minute and obscure, hardly visible, rather sparse, apical impressed areas very shallow, occupying medially about one-third length of disc, becoming narrowly brownish-hyaline along rims, discal pubescence very sparse, thin, erect, entirely pale, apical fasciae very poorly developed, tergum 5 with a pale ochraceous, apical fimbria.
MALE — Length 8 mm.; head broader than thorax; clypeus only slightly convex, projecting about one-half below suborbital line, strongly narrowed apically, surface smooth and shining, very minutely and quite sparsely punctate, the punctures becoming somewhat deeper, coarser and closer at extreme sides; space between margin of vertex and lateral ocelli subequal to their diameter; cheeks much broader than eyes, rather flat, posterior margin quite conspicuously angulate, the rounded angle opposite upper third of eye, surface smooth and shining, minutely punctate, punctures well separated but hardly sparse; length of malar space equal to about one-third basal width of mandible; basal segment of flagellum subequal to 2nd segment; process of labrum short, rather broad, slightly narrowed to the broadly truncate apical margin; mandibles elongate, strongly bowed, with a distinct, inner, subapical tooth located about one-fourth of length from tip, overlapping nearly one-half; pubescence of head, thorax and legs greyish-white, slightly tinged with yellow; thoracic integument dull, tessellate, punctures of scutum very minute and obscure, hardly visible, rather close but very obscure, barely visible on the somewhat shining scutellum; pleura with a very few shallow, obscure punctures anteriorly; dorsal area of propodeum oblique, triangle finely tessellate, very obscurely substriate along basal margin; basitarsi more or less testaceous, very slender and elongate, considerably narrower than their tibiae; 2nd submarginal cell considerably shorter than 3rd, receiving 1st recurrent near apex; abdominal terga rather smooth, somewhat shining, punctures exceedingly minute and obscure, barely visible, well separated but not sparse, apical impressed areas very shallow, not at all hyaline, occupying medially nearly one-third length of discs, discal pubescence extremely short, sparse and obscure, apparently entirely pale, fasciae not developed; apical portion of sternum 8 narrow, sides nearly parallel, apex narrowly truncate, clothed beneath with short, pale pubescence; penis valves slender apically, quite conspicuously dilated basally, dilated area grooved laterally, gonocoxites rather slender, somewhat dilated apically, gonocoxal lobes quite strongly produced, rather narrow, narrowly rounded apically.
