(Figs. 52 – 55)  
 Diagnosis. Thorax dark-brown to black, shiny dorsally, with sparse brown pruinescence on notopleuron, posterior third of scutum, margin of scutellum and mesopleura; thoracic setae brown, thin, slightly elongate, long and strong on margin of pronotum; wing hyaline with basal third smoothly brownish, stigma absent; legs brown except coxa, trochanter and femur of hind leg dark brown and tarsomeres 1 and 2 of fore and mid legs yellow; abdomen very long, 4.8 times longer than thorax; abdomen and legs clothed in brown bristles.   
 Description. Holotype male. Body: 6.5 mm. Wing: 3.7 mm. Antenna placed slightly above middle of head; postpedicel elongate, narrow, 3.3 times longer than scape and pedicel combined. Face narrowly dichoptic. Pair of ocellar setae long, slender, divergent and erect. Postcranium with brownish pruinescence; occipital setae long and dark, uniserial, sparse.   
Thorax dark brown to black, shiny dorsally, with sparse brown pruinescence on notopleuron, posterior third of scutum, margin of scutellum and mesopleura; thoracic setae brown, thin, slightly elongate, stronger on margin of pronotum; acr and dc uniserial; 2 npl long and strong, longer than apical scutellar pair; scutellum with 1 apical pair divergent and 3 thin lateral pairs short, about one-third length of apical pair.  
Wing narrow; hyaline, with basal third evenly brownish, stigma absent; R4+5 and M1 parallel.  
Legs brown except coxa, trochanter and femur of hind leg dark brown and tarsomeres 1 and 2 of fore and mid legs yellow. Bristles brown. Hind femur very long and discreetly thickened, 6.3 times longer than wide; hind tibia tubular. Outstanding bristles: fore tibia with 1 short anterior bristle, 1 long posterior preapical bristle reaching middle of corresponding tarsomere 1 and 1 short posteroventral preapical bristle; mid tibia with 5–6 long, strong bristles and several slender bristles along entire length of dorsal surface, some strong elongate anteroventral bristles, 1 ventral apical bristle very long reaching apex of corresponding tarsomere 1 and some short preapical bristles; fore and mid tarsomere 1 with 1 anterior and 1 posterior long and strong preapical bristles; mid tarsomere 1 with 1 dorsal preapical, 1 dorsal sub-basal and 1 anterior sub-basal bristles long, 1 very long posteroventral sub-basal bristle reaching middle of corresponding tarsomere 2, 1 short and strong posteroventral bristle near base; hind trochanter with 2 spines ventrally; hind femur with 1 dorsal bristle near apex, 2 anterior (1 at distal two-thirds and 1 preapical) and some rather stout bristles near base, 10 spine-like elongate anteroventral bristles, 16 disordered spine-like very short ventral bristles near apex of femur, 7 spinelike posteroventral bristles on distal half and 3 on basal quarter; hind tibia tubular, with 1 robust dorsal preapical bristle and 4–5 elongate and less stout anterodorsal bristles; hind tarsomere 1 with 2 anteroventral subbasal and 1 anterior preapical thickened bristles.  
Abdomen notably longer than usual, 4.8 times longer than thoracic length; shiny, dark-brown, with sparse brown pruinescence on Tg1, Tg8 and sternites; bristles brown, short, sparse, longer on Tg1 and Tg2; St8 with some elongate yellow bristles on distal margin. Terminalia (Figs. 52–55): long and slender; right epandrial lamella twice longer than left lamella; right hypandrial lobe long, triangular, with short thin bristles, left hypandrial lobe not developed; dorsal bridge complete; postgonites slender, ribbon-like.
