Body length including forewing: male 4.3–4.5 mm (N = 10); female 4.8–5.1 mm (N = 10); forewing length: male 3.5–3.7 mm (N = 10); female 3.5–4.6 mm (N = 10). COLORATION. General color greenish stramineous ( Fig. 5 ); two spots on vertex and impression in fork of median carina of frons orange ( Fig. 5G ). Forewings ( Fig. 6D ) translucent-ochraceous, a small round callus near ScP-R fork and another near CuA fork piceous, a faint transverse stripe across middle of clavus, and apical veins at margin brown. Hindwings yellowish hyaline, veins concolorous. Abdomen light nacarat, slightly lighter ventrally, and disc of first abdominal segment ventrally and dorsally black. HEAD AND THORAX.Vertex ( Fig. 6A ) at midline shorter than wide at base (0.27:1), width at apex narrower than at base (0.58:1). Frons ( Fig. 6C ) 1.44 times longer in middle line than widest part, narrower at apex than at base (0.95:1). Postclypeus ( Fig. 6C ) wider at base than frons at apex. Antennae ( Fig. 6C ) with first segment longer than wide at apex (1.08:1), shorter than second segment (0.52:1). Pronotum ( Fig. 6A ) at midline longer than vertex (1.53:1). Mesonotum ( Fig. 6A ) 3.74 times as long as vertex and pronotum combined in middle line. Forewing ( Fig. 6D ) in middle line longer than wide at widest part (3.12:1). Spinal formula of hind tibia 5-8-5 or 5-9-5. MALE GENITALIA. Anal segment ( Fig. 6E ) moderately large, ring-like, without anal process, anal style distinctly elongate and narrow, nearly lanceolate in lateral view ( Fig. 6F ). Pygofer in profile ( Fig. 6F ) with dorsal margin shorter than ventral margin, posterior margin convex, in posterior view ( Fig. 6G ) with opening longer than wide, ventral margin broadly concave, without medioventral process. Genital styles ( Fig. 6H–I ) long, reaching basal anal segment, laterally compressed, nearly paralleled, in posterior view ( Fig. 6H ) with outer apical angle rounded, inner apical angle bifurcate, in lateral view ( Fig. 6I ) with upper ⅖ with posterior edge excavated, apical part distinctly curved inward, with inner edge angularly directed ventrally. Aedeagus ( Fig. 6J–K ) long, tubular, with distinct phallotheca, with basal part lying between two valvular processes of phallotheca, deflecting leftward, apical part recurved downward and reaching ⅔ of phallotheca. Phallotheca shaft laterally compressed, narrowing distad and strongly deflexed, recurved caudad at blunt apex. Host plant Bambusa dolichoclada Hayata , B. oldhamii Munro , B. multiplex (Lour.)
