Homoneura subvittata Malloch, 1927: 170. Type locality: China (Taiwan). Holotype male in SDEI. Homoneura (Homoneura) subvittata: Malloch, 1929: 54. Sasakawa, 1987: 6; 1992: 203; 2002: 58. Shewell in Delfinado & Hardy, 1977: 209.
Diagnosis. Ray pubescent. Mesonotum with a pair of medial stripes extending to tip of scutellum, a pair of stripes along dc rows extending to postsutural second dc, a pair of short lateral stripes behind transverse suture; acr in irregular 8 rows. Wing pale yellow with brown spots, including elliptical apical spot on R2+3, small round apical spot on R4+5, two spots between r-m and apical spot on R4+5, transverse stripe-like apical spot on M1, brown clouds on r-m and dm-cu; subcostal cell brown apically. Abdomen yellow, male tergites 1–6 (female 1–7) with black triangular middle strip and tergites 3–6 (female 3–7) with a pair of narrow brown lateral bands along posterior margin.
Redescription. MALE. Body length 4.1–4.4 mm, wing length 4.1–4.5 mm. FEMALE. Body length 3.9–4.1 mm, wing length 3.9–4.1 mm.
Head (Figs 291, 292) yellow. Frons nearly as long as wide and parallel-sided, with a pair of brown medial stripes extending to ocellar triangle; ocellar triangle brown; oc shorter than anterior or; anterior or shorter than posterior or; gena as high as 1/8 height of eye. Antennal 1st flagellomere 1.3 times longer than height; ray pubescent, with longest ray shorter than 1/4 height of 1st flagellomere. Proboscis and palpus pale yellow.
Thorax (Fig. 293) yellow. Mesonotum with a pair of medial stripes, a pair of stripes along dc rows extending to postsutural second dc, a pair of short lateral stripes behind transverse suture; acr in irregular 8 rows, prsc shorter than postsutural 1st dc.

Mid femur with 7 a; mid tibia with 2 strong preapical ad and 1 strong apv. Hind femur with 1 preapical ad; hind tibia with 1 preapical ad and 1 short apv. Wing (Fig. 289) pale yellow with brown spots: elliptical apical spot on R2+3, small round apical spot on R4+5, two spots between r-m and apical spot on R4+5, transverse stripe-like apical spot on M1, 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 4.1:1.6:1; r-m before middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1:1.6; ultimate section of CuA1 about 1/7 of penultimate. Halter pale yellow.
Abdomen (Fig. 294) yellow, male tergites 1–6 (female 1–7) with black triangular middle strip and tergites 3–6 (female 3–7) with a pair of narrow brown lateral bands along posterior margin. Male genitalia (Figs 295–299): syntergosternite circular with dorsal setulae; epandrium with a deep subapical concavity and a blunt triangular process on posterior margin in lateral view; surstylus claviform with several long setulae and tiny teeth, bulged at middle in lateral view; hypandrium broad, hypandrial apodeme long; pregonite short and broad, with four long setae; aedeagus with a pair of small lateral teeth, a deeply distal incision and a pair of crossed subuliform dorsal processes in ventral view, aedeagal apodeme long.
