Male. 81. protandrium and epandrium, lateral view; 82. epandrial complex, posterior view; 83. protandrium, anterior view; 84. aedeagal complex, ventral view; 85. aedeagal complex, lateral view. Scale 0.5 mm. Distribution. China ( Yunnan ). Remarks. The new species is somewhat similar to Homoneura ( Homoneura ) flavida Shi &Yang from China ( Yunnan and Hainan ) in the following characters: face without spots and parafacial brown to blackish brown, abdominal tergite 6 yellow with a small brown median spot; gonopod columniform. But it can be separated from the latter by the following features: wing without markings; protandrium with a long narrow furcated ventral process; surstylus broad, hairy, digitiform; aedeagus without distinct apical incision, and with a pair of lateral median teeth, a pair of ventral teeth and a pair of dorsal teeth. In H . ( H .) flavida , the wing has a brown stripe on dmcu ; the surstylus is nearly knife–like; aedeagus has a distinct apical incision, the aedeagus has no distinct process (Shi & Yang 2009). Etymology. Latin, longi -, prefix meaning long + processa , meaning process, referring to the protandrium having a long, narrow, furcated ventral process.
