(Figs. 56 – 60)  
 Diagnosis. Thorax brown to black, brown pruinose except basal two-thirds of scutum shiny; thoracic setae brown, very short, thin; wing sub-hyaline, stigma pale, inconspicuous; legs yellow except distal two-thirds of hind femur, distal third of hind tibia and tarsomeres 3 to 5 brown; abdomen and legs with yellow bristles.   
 Description. Holotype male. Body: 3.8 mm. Wing: 3.6 mm. Antenna placed at middle of head; postpedicel and arista lost. Face holoptic, as long as frons. Pair of ocellar setae lost. Postcranium with brownish pruinescence; occipital setae short, sparse.   
Thorax brown to black, brown pruinose except basal two-thirds of scutum shiny; thoracic setae brown, very short and thin; acr and dc uniserial; 2 npl as long as apical scutellar pair; scutellum with 1 apical pair long, divergent and 5 thin lateral pairs short and weak, about one-third the length of apical pair.  
Wing narrow; sub-hyaline; stigma absent; R4+5 and M1 parallel.  
Legs yellow except for distal two-thirds of hind femur, distal third of hind tibia and all tarsomeses 3–5 brown. Bristles yellow. Hind femur thickened, 4.6 times longer than wide; hind tibia tubular. Outstanding bristles: fore tibia with 1 short anterior preapical bristle and 1 long posterior preapical bristle crossing half of corresponding tarsomere 1; mid tibia with 1 short dorsal bristle in middle and 1 short dorsal sub-basal and 1 long posterior apical bristle reaching apex of corresponding tarsomere 1; mid tarsomere 1 with 1 long posteroventral bristle near base, reaching base of tarsomere 2 and 1 long dorsal preapical bristle; hind trochanter with some strong yellow bristles ventrally; hind femur with 1 dorsal bristle on distal quarter, 1 anterior on distal fifth, 9 spine-like elongate anteroventral bristles, 11 ventral thorns decreasing in length towards apex, posteroventral surface with 4 spine-like bristles on distal quarter and 1 sub-basal.  
Abdomen 4 times longer than thoracic length; shiny brown, with sparse brown pruinescence on Tg8 and sternites; yellow and thin bristles, longer on Tg1 and Tg2; St 8 with long yellow bristles on distal margin. Terminalia (Figs. 56–60): short, left epandrial lamella with very long and stout bristles distally; hypandrium elongate, right hypandrial lobe long, triangular, with long thin bristles, left hypandrial lobe not developed; dorsal bridge complete; postgonites slender, ribbon-like.
