( Fig. 1 ) Diagnosis. Belonging to Clinocera lineata group. Thorax dark brownish yellow with blackish dorsum; laterotergite and lateral margin of mesonotum dark yellow. Fore femur with only one row of v. Male. Body length 3.4 mm , wing length 2.7 mm . Head black, gray­brown dusted; upper occiput with a pale pollinose median band extending to ocellar tubercle; face pale pollinose except lateral margin dark and graybrown pollinose. Hairs and bristles on head black; uppermost 3 postocular bristles long; 2 vt long and strong; ocellar tubercle weak with 2 long oc and 2 very short posterior hairs. Antenna black; scape indistinct in lateral view with black dorsal bristles, pedicel with circlet of black apical hairs; first flagellomere short and conical (1.1 times longer than wide), indistinctly pubescent; arista slightly thickened, 5.5 times as long as first flagellomere, dark brown, indistinctly pubescent. Proboscis dark brown with black and pale hairs; palpus dark brown with black hairs and 1 black thin apical bristle. Thorax dark brownish yellow with blackish dorsum, pale gray dusted; laterotergite and lateral margin of mesonotum dark yellow. Hairs and bristles on thorax black; 1 h, 1 ph, acr absent, 5 uniformly long dc, 2 npl (outer one very short and hair­like), 1 short psa shorter than dc; scutellum with pair of long sc as long as dc; laterotergite with hairs on outer portion. Legs dark brown; coxae and trochanters brownish yellow. Hairs and bristles on legs black. Femora each with 1 av and 1 pv at tip; fore femur with row of short av; fore tibia with row of ad, hind tibia with row of 8 pd, 3–4 av and 5–6 pv on apical half. Wing hyaline, tinged with grayish; veins dark brown. Squama dark brown with black hairs. Halter dark brown. Abdomen distinctly longer than head and thorax together, black, pale gray dusted; tergum 7 divided into 2 lateral sclerites connected by the membrane; tergum 8 linear, but sternum 8 large. Hairs on abdomen short, sparse, blackish. Male genitalia ( Fig. 1 ): Cercal plate with long bristles, clasping cercus distinctly sclerotized, long, spine­like; epandrium large and broad with rounded apex, its surstylus curved inward with narrow base and very wide apex bearing dorsal ridge; hypandrium narrow apically; phallus with hook­like apex. FIGURE 1 . Clinocera guangdongensis sp. n. , male genitalia, lateral view. Female: unknown. Material: Male holotype . CHINA : Guangdong, Fugang, Guanyinshan Mountain, 15. V. 2004 (in 75% ethanol, leg. Ding Yang, in CAU). Etymology: This specific name refers to the type locality Guangdong. Remarks. The new species is very similar to C. sinensis Yang et Yang, 1995 from Zhejiang in having the spine­like clasping cercus and surstylus with a dorsal ridge, but can be distinguished from the latter by the thorax mainly dark brownish yellow, clasping cercus slightly curved backward apically and phallus distinctly swollen subapically. In C. sinensis , the thorax is entirely black, the clasping cercus is slightly curved forward apically, and the phallus is not distinctly swollen subapically ( Yang & Yang, 1995 ). Up to now four species of the genus Clinocera are known to occur in China . Two species, C. sinensis Yang et Yang and C. wui Yang et Yang , are distributed in the Central China Region. One species, C. guizhouensis Yang, Zhu et An is distributed in the Southwest China region while one species, C. guangdongensis sp. n. , is distributed in the South China Region. It is highly possible that more species will be found in China .
