( Figs. 1 – 7 View Figs View Figs )
Diagnosis. – Ocellar setae absent; third tergite without dark brown patches; surstylus with ca. 27 strong setae on inner surface ( Figs. 4, 5 View Figs ); cercus nearly triangular ( Fig. 4 View Figs ); aedeagus (basiphallus) expanded and extroverted in ventral view ( Fig. 6 View Figs ), triangular basally in lateral view ( Fig. 7 View Figs ).
Material examined. – Holotype: male, CHINA: Jianfengling (18°41'N 108°52'E, alt. 900 m), Hainan, ex. fallen logs, coll. Hongwei Chen, 19 May 2004. GoogleMaps
Description. – Head ( Fig. 4 View Figs ): Eye red. Postvertical setae long, ca. 0.4 times as long as inner vertical setae, inserted at vertical ridge. Frons narrow, black, with dense grey pollinosity. Ocellar triangle black. Pedicel and first flagellomere brown; arista short plumose with pubescence basally. Face, clypeus, postgena and occiput glossy black. Gena glossy black, narrow and linear. Palpus large, black, lobe-like, with a few short setae on lateral margin. Vibrissa prominent; other orals small.
Thorax: Black with dense grey pollinosity. Postpronotal lobe with 1 long and 3 short thick setae. Acrostichal setulae in ca. 8 irregular rows. Anepisternum lacking setulae. Katepisternal setae 2. Scutellar black, yellow on tip; basal setae divergent; apical setae cruciate. Subscutellum swollen in lateral view. Wing ( Fig. 1 View Figs ): Hyaline, veins grey yellow. Basal medialcubital crossvein absent. C 1 setae 2, thick. Costal vein with strong setae on ventral surface between R 2+3 and R 4+5. C3F = 0.25. R 2+3 straight. Halters white.
Legs: Yellow except for dark brown third to fifth tarsomeres. Fore femur without long setae on posterior surface; midfemur with a row of strong setae on anterior surface ( Fig. 2 View Figs ); apical setae present on fore- and hind tibiae; preapical setae present on mid tibia only. Mid tarsus ventrally with 2 rows of minute cuneiform setulae; hind tarsus lacking minute cuneiform setulae. All first tarsomeres longer than the rest combined.
Abdomen: All tergites yellow; fourth to sixth tergites medially and sublaterally with dark brown patches; six tergite very small, narrowed on lateral margins ( Fig. 4 View Figs ). Sternites yellowish except for brown on fifth; sixth sternite (queried) developed ( Figs. 6, 7 View Figs ).
Male terminalia: Epandrium not constricted mid-dorsally, with ca. 12 setae and pubescence ( Fig. 4 View Figs ). Cercus separated from epandrium, pubescent and setigerous ( Fig. 4 View Figs ). Hypandrium anteriorly broadened, with 2–3 pairs of paramedian setae, mid-anteriorly connected with ventral branch of aedeagal apodeme ( Figs. 6, 7 View Figs ). Decasternum forming small posteromedian lobe, baso-laterally contiguous to posterior ends of hypandrium and anteroventral corners of epandrium ( Figs. 6, 7 View Figs ). Aedeagus sclerotized dorsally, membranous ventrally ( Fig. 7 View Figs ). Aedeagal apodeme long, rod-shaped, with a ventral branch submedially ( Figs. 6, 7 View Figs ).
