Diagnosis: This species can be recognized by the peg-like projection and dense dark bristles on the hind trochanter ( Fig. 147C View FIGURE 147 ); the unusual shape of the distal tarsomere of the fore tarsus, with a handle-shaped base that gradually widens towards the tip ( Fig. 151C View FIGURE 151 ); abdominal sternites 2–5 with distinct dark spines along posterior margin; surstyli elongated in dorsal view ( Fig. 7A View FIGURE 7 ); left gonopod longer than right one ( Fig. 7B View FIGURE 7 ); phallic guide with five spines dorsal-dorsolaterally, one longer than others.
Description: MALE: Body length: 4.1 mm. Head. Flagellum acuminate, yellow. Face silvery pollinose. Frons, upper part shining black, lower part distinctly silver pollinose with a golden tinge; eyes touching for distance equal to 3.5 times the length of ocellar triangle. Occiput silvery pollinose, less so on upper half. Thorax. Postpronotum pale, slightly brownish, with 15–17 distinct long pale bristles. Mesonotum (viewed obliquely from front) brownish pollinose, anterior part slightly silver pollinose; grayish also from the side. Scutellum brownish pollinose and with 20–22 long bristles along the distal edge. Dorsocentral bristles undeveloped, indistinct, numerous pale bristles around postpronotum. Halter, knob pale, stem brown. Legs. Mid coxa with 4–6 extra long, dark bristles, hind coxa 4–5 shorter dark bristles. Trochanters and femora black, shining ventrally, silvery pollinose posteriorly except shiny hind femur; knees, and distal extremity of tibiae yellow-brown (tibiae otherwise black), tarsal segments dark brown, yellowish ventrally. Hind trochanter without a keel, but with a distinct, blunt peg on the distal end with a few dark bristles (8–10) basally to the peg ( Fig. 147C View FIGURE 147 ). Ventroapical row of spines on fore femur missing, a patch of 6–7 short dark spines are present at 1/3 from distal end; 3–4 short, black spines on mid femur; no spines on hind femur, only 12–14 dark bristles posteriorly on distal half positioned on a slight keel (up to as long as half the width of hind tibia at the distal end). Fore and mid femora with 6–8 ventrobasal bristles. Subapical (distal) spines on first four tibiae absent. Hind tibia covered with dense long dark bristles ventroapically; last tarsomere of fore tarsi longer than other tarsomeres, with a long handle-type base and gradually widening towards tip, provided with strong dark bristles dorsally; the segment itself is bent ( Fig. 151C View FIGURE 151 ). Hind tarsomeres all flattened, hind metatarsus almost as long as 2–4 combined, last tarsomere long and broad, almost as broad and longer than tarsomere 2 ( Fig. 151D View FIGURE 151 ); bristles are missing dorsally on hind metatarsus in the median line but are present anterior and extensively on posterior edge. Pulvilli 1/3 as long as last tarsomere of fore tarsi, as long as last tarsomere of mid tarsi and half as long as last tarsomere of hind tarsi. Wing. Length: 4.2 mm. Upper side of basal costal cell with two long light bristles. Fourth costal section 3.5–4 times as long as third costal section (3 rd section appears to be unusually short). Cross-vein r-m at 3/5 of discal cell, distal to middle. 7–8 very strong, dark setulae on tegula. Abdomen. Dissected. Tergite 1 silvery grey. Lateral bristles on first tergite present, 16–18 long pale bristles in a group (as seen in species of Claraeola Aczél ) up to 1.6–1.8 times as long as the width of hind femur at distal tip in lateral view. Sternites 2–5 with distinct dark spine along posterior margin in each segment. Postabdomen in dorsal view: Dissected. Genitalia. Genital capsule in dorsal view: epandrium and surstyli dark brown. Epandrium wider than long (MLE:MWE = 0.6). Surstyli rather symmetrical, broadened at base, elongated, pointing towards each other at apex, left is wider than right one ( Fig. 7A View FIGURE 7 ). Genital capsule in ventral view: gonopods unequal, left is longer than right one, hypandrium broad, subepandrial sclerite rectangular-shaped ( Fig. 7B View FIGURE 7 ), phallic guide with five spines dorso- dorsolaterally (the longest one twice as length as others); genital capsule in lateral view: both surstyli curved towards sternite ( Figs 7C–D View FIGURE 7 ).
FEMALE: Unknown.
Etymology: The Latin ansa for handle or haft, refers to the handle-shaped distal fore tarsomere.
