MALE—Length 5 mm.; black; face slightly longer than distance between eyes above; eyes slightly convergent below; cheeks considerably narrower than eyes; process of labrum, mandibles, clypeus except lateral apical margins, and small lateral maculae, pale ivory-yellow, the lateral maculations not extending above upper margin of clypeus; facial foveae short and shallow, but quite distinct; space between margin of vertex and lateral ocelli subequal to their diameter; median segments of flagellum slightly longer than broad; punctures of head above very fine, close and deep, becoming somewhat more shallow and more widely separated on cheeks below, very fine and well separated but not sparse below antennae, those on maculated areas coarser but rather shallow and obscure; pubescence of head and thorax very short, thin and obscure, entirely pale; tubercles reddened posteriorly; tegulae yellowish-hyaline; wings hyaline, veins and stigma brownish-testaceous, 2nd recurrent vein very close to apex of 2nd submarginal, the 1st widely removed from base; femora dark, narrowly yellow at extreme tip, front tibiae yellow anteriorly and on outer surface, dark posteriorly, mid and hind tibiae yellow at base and apex, otherwise dark, tarsi and spurs yellow; dorsum of thorax very finely and closely punctate, surface somewhat shining; pleura rather dull, punctures coarser, shallow and more widely separated but not sparse; apical margins of abdominal terga evenly and rather deeply depressed, these areas shining but microscopically pebbled, discs of terga rather dull, punctures of basal tergum very fine and well separated but quite distinct, those of 2nd and following segments minute and obscure, barely evident, discal pubescence very short, thin and obscure, entirely pale; sternum 6 with a median, triangular, apical emargination; wings of sternum 7 semicircular, tips slightly recurved, bearing a very small brush of short setae; apical process of sternum 8 quite strongly flexed ventrally, tip truncate and bearing a quite dense apical tuft of setae; gonostyli rather robust, median portion with an inner, dorsal carina, tips slightly flexed toward median line and bearing a conspicuous tuft of rather short setae; penis valves slender, shorter than gonostyli.
