Diagnosis. This species is distinguished from Asioclinocera formosana gen. et sp. nov. by the pale brown scutum, with dark median vittae and dark border around pruinescence of prescutellar depression; anteroventral and posteroventral rows of setae longer than half width of fore femur; and shape of the clasping cercus.
Etymology. The species is named after the Chinese province of Yunnan.

Description (wing length 3.3–3.8 mm). Male. Head ( Fig. 5 View Figs 4–5 ): Oval, tapered ventrally, dark brown. Face with thin pruinescence, narrower than width of antennal bases. Ocellar triangle with pair of straight, anteriorly-directed ocellar setae, longer and stronger than vertical setae; pair of vertical setae. Postocular row of setae on upper half strong; lower half slender; occipital setae scattered, setae posterior to mouth slender. Antenna brown ( Fig. 5 View Figs 4–5 ); scape shorter than pedicel, with several setulae; pedicel with circlet of apical setae; postpedicel short-ovate; basal segment of arista-like stylus wider than long; arista-like stylus as long as head height. Thorax: Scutum pale brown, with thin pruinescence; medially with broad, dark brown vitta extending to prescutellar depression; prescutellar depression with whitish pruinescence with dark border in anterior view. Pleura pale brown, concolourous with scutum ( Fig. 5 View Figs 4–5 ). Scutal setae long, slender; acrostichals absent; 5 dorsocentral setae; 1 postpronotal seta; 1 presutural supra-alar seta; notopleuron with several anterior setulae, 1 upper posterior notopleural seta; 2 postsutural supra-alar setae; 1 postalar seta; pair of scutellar setae, closely approximated, longer than prescutellar dorsocentral. Laterotergite with several long, slender setae. Legs: Pale brown, concolourous with pleura, segments gradually darker apically. Fore femur with rows of long, fine anteroventral and posteroventral setae, longer than half width of femur, similar to length of spine-like seta ( Fig. 5 View Figs 4–5 ); preapical anteroventral spine-like seta longer than width of tibia. Fore tibia with row of strong, short anteroventral setae, less than half width of tibia ( Fig. 5 View Figs 4–5 ). Mid tibia with basal posterodorsal seta, twice width of tibia. Hind tibia with thin anteroventral seta on distal third, less than twice width of tibia; row of strong, erect posterodorsal setae on distal third, longer than width of tibia. Wing ( Fig. 4 View Figs 4–5 ): Infuscate, without cloudy pattern; R 4 distinctly arched, ending in costa near middle between R 2+3 and R 5. Halter brown. Abdomen: Sclerites dark brown, darker than thorax, with short, scattered setae and thin pruinescence. Tergum 7 membranous medially; sternum 7 with anterolateral corner prolonged into distinct projection. Tergum 8 roundly expanded laterally with numerous long setae; sternum 8 as long as sternum 7, posterior margin prolonged beneath hypandrium. Terminalia ( Figs 7 View Figs 6–7 , 9 View Figs 8–9 ): Hypandrium rectangular, similar in length to epandrium, apex slightly tapered with 6 apical setae. Phallus with broad triangular base aris- ing from hypandrium, stout apical section sinuous; apex expanded with narrow, membranous crest. Ejaculatory apodeme broad, rounded, narrowly extended into base of phallus. Epandrium rounded, with long setae mostly along dorsal margin. Cercal plate with long setae on apical half. Clasping cercus digitiform, tapered apically with rounded apex; strong, thickened setae along inner posterior margin and inner apex; apex crowned with 3 spine-like setae; without peg-like setae on inner surface. Surstylus digitiform, strongly arched, tapered to rounded apex; longer than length of clasping cercus.
Female. Similar to male except face slightly broader than width of antennal sockets.
