Wing (Fig. 19) pale yellow, dark on apex of subcostal cell, apices of R 2+3, R 4+5 and M 1, basal portion of R 4+5 beyond crossvein r­m, and on dm­cu; costa with 2nd, 3rd and 4th sections in proportion of 5:1.8:1.2; crossvein r­m before middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 3.2:2.8; ultimate section of CuA 1 about 1/8 of penultimate. Halter yellow. Abdomen yellow. Male sternite 5 with concave distal border. Genitalia (male) (Figs 20–24): Protandrium semicircular, 7th spiracle without surrounding setulae; surstylus basalyy fused with epandrium, apically furcate with an outer and an inner processes; hypandrium without distinct apodemes, gonopod long and pointed apically; aedeagus long, pointed apically, with narrow apical incision. Type material. Holotype male deposited in CAU, Guizhou: Fanjingshan Mountain (27°55'N, 108°41'E) (21002200 m), 2002. V. 31, Ding Yang. Paratypes 15 males 10 females, same as holotype; 3 males 4 females, Guizhou: Fanjingshan Mountain (27°55«N, 108°41'E) (18002200 m), 2002. VI. 1, Ding Yang. Remarks. The new species is somewhat similar to <i>Homoneura (Homoneura) grandis</i> (Kertész, 1915) from Taiwan, but can be easily separated from the latter by the surstylus with the pointed tip. In <i>grandis</i>, the surstylus is rounded at tip (Malloch 1929). Etymology. The species is named after Prof. Maofa Yang. Distribution. China (Guizhou).
