Prothorax light brown, subquadrate, all angles somewhat rounded with some black irregular stripes on it. Legs light brown. Wings hyaline and veins light brown. Forewing length 6.0 mm, body length 6.5 mm. Tergum 9 sclerotised, with a X-shape central membranous area. Sternum 9 basally with a tongue-like vesicle bearing dense hairs, apically with a subgenital plate wider than long and rounded apically. Tergum 10 with strongly sclerotised lateral process beak-like somewhat acute and curving inwards apically and a small spine at the middle of lateral process in dorsal view, thick basally and slightly curved upwards apically in lateral view. Mid-anterior sclerite sclerotised, posterior margin more sclerotised; one pair of transverse triangle sclerite weakly sclerotised. Epiproct with a simple curved process, erect hook-like apical portion curved inwards. Subanal lobe strongly sclerotised at base, trident-like apically in ventral aspect and membranous at its apex (Figs 1 b, 7 , 8 ).
