Description. The descriptions are reproduced from Zhu (1988), Ding and Hu (1991) and Ding (2006), and redescriptions of female genitalia are made based on the illustrations of Zhu (1988). “Length of body 2.80 mm (male), 3.00 mm (female); including forewing 4.60 mm (male), 5.00 mm (female); tegmen length 3.90 mm (male), 4.30 mm (female).”

Coloration. “Vertex brown, carinae yellowish white, except lateral carinae blackish brown. Frons and genae brown, clypeus blackish brown, carinae yellowish white, except the apex of median carina of clypeus blackish brown. Antennae with first segment blackish brown, median part with longitudinal brown stripe, second segment pale brown, with an obliquely dark brown stripe from base of outer margin to middle of inner margin. Pro- and mesonotum brown, except lateral areas of pronotum and carinae yellowish white, carinae of pronotum and median carina of mesonotum bordered by blackish brown. Thorax with ventral areas blackish brown. Legs brown or dark brown, except basal half of hind femora blackish brown. Forewing speckled with blackish markings, in dark portion veins bear white spots. Abdomen blackish brown, except posterior margin area of each segment brown. Male genitalia blackish, anal segment brown, and process of anal segment dark brown. Aedeagus dark brown.”

Head and Thorax. “Head including eyes wider than pronotum (1.09–1.15:1). Vertex wider at base than long submedially about 1.9:1. Frons longer in middle line than wide at widest part about 1.8:1, wider at base than at apex about 1.25:1. Antennae with first segment longer than wide at apex about 1.3:1, shorter than second segment about 0.71:1. Pronotum equal to vertex submedially. Mesonotum longer than pronotum and vertex combined (2.10:1). Forewing longer in middle line than wide at widest part about 2.66:1.”

Male Genitalia. “Male anal segment ( Ding 2006: Figs 100: D, F) cylindraceous, without process. Pygofer in caudal view ( Ding 2006: Figs 100: C, G) with opening larger in length than width. Aedeagus ( Ding 2006: Figs 100: E) broad, short, compressed, forked at apex, the slender branch spine-like, the thick branch with basal half same length as the slender one, apical half suddenly curved into a spine-like process. Genital styles ( Ding 2006: Figs 100: C, D, I) slender, long, sinuate, reaching to the apex of anal segment, same width at apex as at base, with inner apical angle acute, outer apical angle broad rounded.”

Female Genitalia. Female pygofer ( Zhu 1988: Fig. 5 ) with first valvifers moderately large, second valvifers long, broad and large. Ovipositor about the same length of pygofer. Gonangulum broad and large, hemicycle-like, apex rounded, connected first valvifers and first valvulae.

Host Plant. Indocalamus latifolius (Keng) McClure ( Ding & Hu 1991) .

Distribution. China (Zhejiang: Hangzhou; Anhui: Langyashan).
