Male (Fig. 27) dichoptic, eyes separated by broad shiny frons, face narrower than frons; occiput shiny on upper part and faintly pruinescent on lower part; antenna black, postpedicel long; palpus usually yellowish with darkened apex; labrum about 2X longer than head height, extensively yellowish, only apex brownish; thorax black, pale setose, 1 npl; postpronotal lobe and almost entire mesoscutum shiny (except faintly pruinescent narrow marginal edging); legs extensively yellow, only apical part of femora and tibiae and all tarsi more or less intensively darkened, fore basitarsus slightly incrassate; wing faintly brownish infuscate, axillary incision very obtuse, anal lobe almost absent, anal vein incomplete, halter yellow; abdomen shiny, brownish to black dorsally and usually yellowish to brownish yellow ventrally, pale setose; terminalia directed upwards; cerci separated from each other and from epandrium; cercus with straight upper margin, apex slightly produced beyond apex of epandrium, covered with setulae; epandrium fused with hypandrium, with somewhat produced truncate apical part, covered long pale setae, some spinule-like setulae at apex; subepandrial sclerite entire, with apex recurved as slender projection, extended beyond lower margin of epandrium; hypandrium deeply concave medially, with very narrow slightly sclerotised rim anteriorly, produced as digitiform lobes posterolaterally, lobes covered with long, pale setae; phallus well exposed, pale yellow, mostly uniformly thin, somewhat thicker on basal part, gently curved; ejaculatory apodeme far before basal curvature of phallus, very close to base of cerci, with two small lateral wings.
