Wing ( Fig. 18 ) pale yellow, brown apical spots on R 2+3 , R 4+5 and M 1 entirely separated; basal edge of brown apical spot on R 2+3 distinctly behind vertical level of spot on R 4+5 and M 1 , basal edge of apical spot on R 4+5 behind vertical level of spot on M 1 ; one round spot on R 4+5 situated at middle point of distance between crossveins r-m and dm-cu; brown cloud on crossvein dm-cu, constricted at middle; subcostal cell brown; 2nd (between R 1 and R 2+3 ), 3rd (between R 2+3 and R 4+5 ) and 4th (between R 4+5 and M 1 ) sections in proportion of 3.4:1.4:1; r-m before middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1:1.6; ultimate sections of CuA 1 about 1/8. Halter pale yellow. Abdomen ( Fig. 13 ) yellow. Male genitalia ( Figs 17 , 19−23 ): syntergosternite 7+8 circular, a seta dorsal to spiracle; epandrium broad in lateral view; surstylus light color and narrow at base while dark yellow and broad at apex, nearly trapeziform with two long setulae in lateral view; hypandrium reverse U-shaped; pregonite round apically in venral view, postgonite hook-like in lateral view; phallus slender in ventral view and broad in lateral view; phallapodeme shorter than phallus. FEMALE. Unknown. Type Material. Holotype ♂ ( IMAU ), CHINA , Shaanxi Province , Hua County , Gaotang Town , Dongyu Vil- lage, huangbiangou, 1070 m , 7. VII. 2014 , Lei Zhang. Distribution. China ( Shaanxi ). Remarks. The new species is similar to Homoneura ( Homoneura ) zhangjiajiensis Shi & Yang, 2014 from China ( Hunan ), but the latter has the following features: the surstylus being narrow columnar in lateral view and being broad with tiny setulae in posterior view; the postgonites being triangular with sharp apex in lateral view. Etymology. Latin, bi -, meaning double + colorata , meaning colorful, referring to the surstylus being light color at base and dark yellow at apex; a feminine adjective.
