Mid femur with 5 a and 1 app ; mid tibia with 1 strong preapical ad and 2 strong apv . Hind femur with 1 preapical ad and a row of weak av on apical 1/2; hind tibia with 1 weak preapical ad and 1 short apv . Wing ( Fig. 8 ) slightly yellow, with brown transverse stripe-like apical spot on R2+3 confluent with subapical spot on R4+5; brown subapical spot on M1 partly confluent with subapical spot R4+5; basal edges of brown spots on R2+3 and R4+5 with same vertical level of dm-cu ; brown clouds on r-m and dm-cu , subcostal cell brown apically; costa with 2nd (between R1 and R2+3), 3rd (between R2+3 and R4+5) and 4th (between R4+5 and M1) sections in proportion of 3.7:1.5: 1 mm ; r-m at middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1:1.2; ultimate section of CuA1 about 1/5 of penultimate. Halter pale yellow. Abdomen brownish yellow. Male genitalia ( Figs 128–132 ): syntergosternite circular with dorsal setulae and two small ventral segments; epandrium nearly rectangular with four pairs of dorsal setae; surstylus consisting of a broad claviform outer process with a triangular basal process on ventral margin and a curved subuliform inner process with acute teeth on dorsal margin; hypandrium nearly H-shaped; pregonite absent, postgonite very short triangular, slightly projecting forward in ventral vew; aedeagus slender in ventral view, but broad at middle with a pair of subuliform middle processes and a hamate apical process in lateral view; aedeagal apodeme shorter than aedeagus. Type material. Holotype ♂ ( CAUC ), CHINA , Hainan Province : Ledong, Jianfengling National Nature Reserve, Tianchi, 800 m , 18. V. 2006 , Gang Yao. Paratypes : CHINA , Hainan Province : 1 ♂ ( CAUC ), Ledong, Jianfengling National Nature Reserve, Tianchi, 800 m , 18. V. 2006 , Hui Dong; 2 ♂ , 1 ♀ ( CAUC ), Changjiang, Bawangling National Nature Reserve, Dong’er station, 1000 m , 24–25. V. 2007 , Junhua Zhang. Distribution. China (Hainan). Remarks. The new species is similar to Homoneura ( Homoneura ) gibbosa Sasakawa from Malaysia in wing pattern, subcostal cell brown apically; frons without brown stripe and mesonotum with brown medial stripes, but it can be separated from the latter by the epandrium lack a gibbosity on inner side of anterior ventral corner; the surstylus having double processes; the hypandrium being H-shaped; the aedeagus having a pair of subuliform middle processes and a hamate apical process in lateral view. In gibbosa , the epandrium has a gibbosity on inner side of anterior ventral corner and the surstylus has a short and erected process on the inner side of epandrium; the hypandrium is U-shaped; the aedeagus has a pair of acute middle processes which points forward, without a hamate apical process ( Sasakawa, 1992 ). Etymology. Latin, hamata , meaning hamate, referring to the aedeagus with a hamate apical process; a feminine adjective.
