Mid femur with 5 a and 1 apv ; mid tibia with 1 strong preapical ad and 3 strong apv . Hind femur with 1 preapical ad ; hind tibia with 1 weak preapical ad and 1 short apv . Wing ( Fig. 10 ) slightly yellow, with a narrow brown stripe on dm-cu ; subcostal cell hyaline; 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 2.3 mm : 0.7 mm : 0.4 mm ; r-m at middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1.6 mm : 1.8 mm ; ultimate section of CuA1 about 1/ 10 of penultimate.

Male. 57. protandrium and epandrium, lateral view; 58. protandrium, anterior view; 59. epandrial complex, posterior view; 60. aedeagal complex, ventral view; 61. aedeagal complex, lateral view. Scale 0.1 mm. Abdomen yellow with grayish white pollen; tergites 1–2 with entirely black; tergites 3–5 each with a blackish brown posterior band, and an indistinct brown triangular median spot confluent with the blackish brown posterior band; tergite 6 with a brown median spot. Male genitalia ( Figs. 57–61 ): protandrium circular; epandrium nearly trapeziform, slightly concave on dorsal margin, and with a row of apical hairs and a long bristle in lateral view, surstylus narrow incurved stick–like in lateral view; hypandrium with a pair of short bar–like ventral process, gonopod columniform, slightly curved; aedeagus with a pair of acuate lateral processes, a pair of incurved horn–like apical processes and a deep apical incision. Cerci with a pair of long hairs FEMALE. Unknown. Type material. Holotype 3 ( CAUC ), CHINA , Hainan Province : Baisha, Yinggeling National Nature Reserve ( 1050 m ), 28. VIII. 2005 , Liusheng Chen. Paratypes : 1 3 ( CAUC ), CHINA , Hainan Province : Ledong, Jianfengling National Nature Reserve, Mingfenggu ( 1000 m ), 14. V. 2007 , Kuiyan Zhang. Distribution. China (Hainan). Remarks. The new species is somewhat similar to Homoneura ( Homoneura ) nigritarsis sp. nov. from China (Hainan) in the following characters: face pale yellow without spot; wing with a brown spot on dm-cu ; tergites 3–5 each with a triangular median spot confluent with a blackish brown posterior band and tergite 6 with a brown or blackish brown median spot; protandrium circular, epandrium with a row of apical hairs; surstylus narrow incurved stick–like in lateral view. But it can be separated from the latter by the antennal 1st flagellomere being brownish yellow; the hypandrium having a pair of short bar–like ventral processes; the gonopod being beyond the tip of aedeagus; the aedeagus having a pair of incurved horn–like apical processes and a deep apical incision. In H . ( H .) nigritarsis , the antennal 1st flagelomere is pale brown with a pale yellow basal spot on ventral 1/2; the hypandrium has a small ventral process and the gonopod shorter than the tip of aedeagus; the aedeagus has a pair of subuliform processes curved outwards and a shallow apical incision. Etymology. The species is named after the type locality Yinggeling National Natural Reserve.
