Description.
Male. Head. Antennae black; basoflagellomere short, 1.3 times as long as wide, and ca. two times as long as pedicel, with rounded apex; fossette dorsolateral; arista black and thickened at basal one third, covered with dense microtrichia, ca. two times as long as basoflagellomere (Fig. 28C View Figure 28 ); face and frons black with gray microtrichia, face covered with dense whitish gray or mixed black and whitish gray, and frons mostly with black pile; oral margin shiny, with lateral microtrichose area; lunule shiny black, bare; vertex isosceles, shiny black, except in front of anterior ocellus covered with microtrichia; vertex with long, black pile; ocellar triangle equilateral; eyes covered with dense whitish pile; occiput shiny covered with black pile in upper half, ventrally with gray-yellow pile and dense, gray microtrichia; eye dichoptic, separated by distance of three facets (Fig. 27A View Figure 27 ).
Thorax. Scutum and scutellum black, shiny, covered with dense, erect, black pile; scutum without microtrichose vittae (Fig. 26A View Figure 26 ); posterodorsal part of anterior anepisternum, posterior anepisternum (except anteroventral angle), anterior anepimeron, dorsomedial anepimeron, and posterodorsal and anteroventral parts of katepisternum with long, dark gray or black pile and grayish microtrichia; wings entirely covered with microtrichia, except bare area at basal one third; wing veins dark brown; calypteres gray; halteres blackish; legs black (Fig. 26B View Figure 26 ); pile on legs mostly black or dark gray; metafemur curved and medium incrassate, ca. four times longer than wide; pile on postero- and anteroventral surface ca. one third to half of width of metafemur, slightly shorter than pile dorsally.
Abdomen. Tapering, 1.2 times longer than mesonotum; terga completely dark; terga 3 and 4 without, or with indistinct pair of white microtrichose fasciae; pile on terga mostly black, except anteromedial part of tergum 2 partly covered with whitish pile (Fig. 26A View Figure 26 ); sterna dark brown to black, covered with long black and whitish pile.
Male genitalia. Apical part of anterior surstyle lobe rhomboid shape, ca. two times longer than wide, covered with dense, short pile (Fig. 25D View Figure 25 : al); posterior surstyle lobe oval with basolateral protrusion (lateral hump) (Fig. 25D, E View Figure 25 : bp); hypandrium sickle-shaped, without lateral projections; lingula large (Fig. 25F View Figure 25 : l).
Female. Similar to the male except for normal sexual dimorphism and for the following characteristics: basoflagellomere 1.5 times longer than wide, fossette narrow (Fig. 28D View Figure 28 ); pile on face of variable color, from black to whitish; frons mostly microtrichose, covered with black pile; ocellar triangle covered with black pile; microtrichose fasciae on terga 2-4 narrow (Fig. 26C View Figure 26 ); thorax on lateral sides with variable pilosity color, from black to whitish.
