Description.
Male. Head. Antennae black to dark brown; basoflagellomere narrow and elongated, 1.8 times as long as wide, and 2.5 times as long as pedicel, with rounded tip; large fossette dorsomedial and dorsolateral (Fig. 28A, B View Figure 28 ); arista dark and thickened at basal one third, covered with dense microtrichia; arista long, ca. two times as long as basoflagellomere (Fig. 28A, B View Figure 28 ); face and frons black covered with whitish pile; face covered with indistinct whitish gray microtrichia; frons with dense whitish microtrichia; lunule shiny black, bare; vertex isosceles, with long whitish pile and black pilosity on the ocellar triangle; ocellar triangle equilateral; eyes covered with long, dense, whitish pile (Fig. 27B View Figure 27 ); occiput with whitish pile, covered with a dense, silver microtrichia along eye margin; eye contiguity short, approximately five facets long; vertical triangle: eye contiguity: frons = 4.5: 1: 4.5.
Thorax. Scutum and scutellum black with bluish luster, covered with dense, erect, white pile including wing basis; posterior half of scutum with square shaped area of black pile medially; scutum with indistinct microtrichose vittae; posterodorsal part of anterior anepisternum, posterior anepisternum (except anteroventral angle), anterior anepimeron, dorsomedial anepimeron, and posterodorsal and anteroventral parts of katepisternum with long, whitish pile and grayish microtrichia; wings entirely covered with microtrichia; wing veins dark brown; wing with distinct dark area in apical half (Fig. 29C View Figure 29 ); calypteres whitish; halteres yellowish, with darker capitulum; legs mostly black, except dark brown tarsi ventrally; pile on legs mostly whitish mixed with black ones on femora; metafemur moderately incrassate, ca. three times longer than wide; pile on postero- and anteroventral surface very long, and ca. two thirds of width of metafemur, approximately the same length as pile on dorsal surface.
Abdomen. Tapering, 1.2 times longer than mesonotum; terga dark brown to black; terga 2-4 each with a pair of white microtrichose, wide, oblique fasciae (on tergum 2 triangular); pile on terga long, whitish laterally and at microtrichose fasciae, medially black (Fig. 29A View Figure 29 ); sterna dark brown, covered with long whitish pile.
Male genitalia. Apical part of anterior surstyle lobe rhomboid shape, 1.5 times longer than wide, covered with dense, short pile (Fig. 30A View Figure 30 : al); posterior surstyle lobe oval with basolateral protrusion (lateral hump) (Fig. 30A, B View Figure 30 : bp); hypandrium sickle-shaped, without lateral projections; lingula large (Fig. 30C View Figure 30 : l).
