Diagnosis. Ac biseriate; first flagellomere as long as high; legs entirely dark brown; halter yellow; fore femur with av and pv row of fine setae which are as long as diameter of femur; fore tibia with ad row of setae which are as long as diameter of tibia; mid femur with 3–4 strong ventral setae on basal half; hind femur with anterior row of setae in line with preapical seta.
Description. Male: Length (holotype): body 1.7 mm, wing 1.7 mm. Head: Frons velvet black, with dense brownish pruinosity; eyes converging below antennae and almost contiguous; palpus black with a strong spine-like apical seta; antenna dark brown, first flagellomere about as long as high; lower postoculars black. Thorax: Mesonotum and scutellum dark metallic green, with brownish pruinosity; 5 strong dc; ac biseriate; scutellum with 2 strong marginal and 2 small lateral setae; pleura dark brown shining. Legs: Entirely dark brown, except trochanters pale brown. Fore leg: coxa with anterior setae; femur with av and pv row of fine setae, as long as diameter of femur; tibia with ad row of setae, as long as diameter of tibia or slightly longer on distal 2/3, and with ventral row of setae, as long as diameter of tibia on distal 1/3; basitarsus compressed laterally, with small spine-like ventral setulae; relative podomere ratios: 58, 55, 15/8/12 /10/8. Mid leg: coxa with strong lateral seta; femur with 1 strong anterior preapical seta, and 3–4 strong, spine-like ventral setae which are as long as diameter of femur on distal 1/3; tibia with ad/pd setal pair of strong setae on 1/5 and 1/2, and with 3–4 strong apical setae; relative podomere ratios: 67, 67, 30/14/12 /9/8. Hind leg: coxa with 1 strong lateral seta; femur with a row of strong erect anterior setae in line with preapical seta; tibia with strong ad/pd setal pair at 1/4 and 1/2, 1 strong and long dorsoapical seta, and 2 strong apical setae; relative podomere ratios: 68, 78, 18/ 22/17/12 /9. Wing: Hyaline, with grayish tinge; R4+5 and M parallel; CuAx ratio: 0.7; RMx ratio: 1.7; lower calypter pale brown with fan of dark brown setae; halter yellow. Abdomen: Dark metallic green, with brownish pruinosity; segments 6 and 7 ochreous brown, segment 8 dark brown; hypopygium including cercus dark brown. Hypopygium (Figs. 10 A–B): hypandrium narrow, strongly curved apically; epandrial lobe round, with 2 strong apical setae; ventral lobe of surstylus triangular, with short apical seta; dorsal lobe of surstylus U-shaped, with short, spine-like apical seta and additional small setulae; postgonite slender, with 2 strong dorsal setae; cercus narrow, with 2 strong apical setae. Female: Unknown.
Etymology. The name refers to the conspicuous row of setae on the hind femur.
