Description (Male). Color. Head dark brown; antenna, palpus, thorax, abdomen and hypopygium brown; legs yellowish-brown; wing fumose. Head (Fig. 8 C, D). Eye bridge with 3 rows of facets. Prefrons with 13–30 setae. Clypeus with 0–2 setae. Palpus three-segmented, basal segment with 4–5 setae; 2nd segment with 9–13 setae; 3rd segment with 8–12 setae. Length/width of 4th flagellomere: 2.50–3.65. Thorax. Anterior pronotum with 4–5 setae, episternum 1 with 3–8 setae. Wings (Fig. 10 G). Wing length 2.67–3.41 mm, width/length: 0.34–0.38. c/w: 0.41– 0.53. R1/R: 0.57–0.82. Y/X: 1.01–2.10. Y with 0–2setae, stM with 2–5 setae, M and Cu with numerous setae. Legs. Fore tibia with a comb of 6–9 setae (Fig. 8 E). Length of spur/width of foretibia 1.54–2.25. Length of femur/ length of metatarsus: foreleg 0.65–1.00. Length of metatarsus/length of tibia: foreleg 0.60–0.82, hind leg 0.50– 0.64. Length of hind tibia/length of thorax 2.03–2.73. Fore tibia with 1 dorsal, 7–13 ventral, 3–15 prolateral and 4– 8 retrolateral spinose setae. Tarsal claws with large teeth. Hypopygium (Fig. 8 A, B). Gonocoxite longer than gonostylus. Ventral setosity of gonocoxite sparse, 2–3 setae at the apicoventral corner greatly elongated, setosity dense on intercoxal area of hypopygium. Gonostylus slightly curved, eventually narrowed towards apex; setosity dense at apex, with 3–5 slightly curved subapical megasetae that partly not visible in ventral view. Tegmen slightly wider than long. Sternite 10 with 2–3 setae on each half. N = 16 for all measurements.
Distribution. China (Fujian, Guangxi, Taiwan, Zhejiang, Fig. 11).
Remarks. This species is unique by a rather broad gonostylus with 3–5 slightly curved subapical megasetae, arising from the dorsal side of the gonostylus and only partly visible in the ventral view, and by a densely setose intercoxal lobe of the hypopygium.
Etymology. This species is named after its dense setosity on the intercoxal area of the hypopygium, from the Latin adjective multisetosus, meaning many setae.
