Male habitus. Body color generally dark brown to blackish (Fig. 1a). Head dark brown to black; antennae mostly black but several basal segments brownish; compound eyes black; head much wider than pronotum; pronotum dark brown, generally rectangular with lateral margins slightly convex, surface dark brown with dense brown tiny spots forming reticular structure, as well as scattered larger worm-like brown markings. Legs light brown, but distal portion blackish, tarsi brownish except distal segment darker, tibia of hindlegs with black distal band. Wing membranes brownish, veins dark brown. Abdomen brown with blackish terminal segments.
Male. Forewing length 6.2–6.3 mm, hindwing length 4.9–5.0 mm (n=2). Tergum 9 distinctly sclerotized, anterior margin with a semicircular medial incision, posteromedial incision broad and shallow (Figs. 2a, 4a). Slender vesicle of sternum 9 claviform, length>5X maximum width, slightly constricted at base and subapically (Fig. 4b). Hypoproct basally subquadrate, medially distinctly tapering and apex tubular (Fig. 4b). Tergum 10 darkly sclerotized, with a few tiny spines on either side of a membranous medial concavity below the epiproct and several scars in anteromedial membranous area (Fig. 2a). Cercus slightly sclerotized, simple and short (Figs. 2a, 4a). Epiproct subrectangular (Figs. 2c–d, 4a, 4c), apex tapering apically (Figs. 2c, 4a). Dorsal sclerite (Figs. 2c–d, 4a, 4c), with two stripe-like, black lateral arms ending before apex. Ventral sclerite strongly sclerotized, broad at basal third, then tapering toward tip, apically extending over the dorsal sclerite to form a short apical hook (Figs. 2c–d), apex expanded in a ventral ridge with a row of short black spinules in lateral aspect (Figs. 4c). Paraproct inner lobe (Figs. 2b, 2e, 4b) slightly sclerotized and subtriangular (Fig. 2b); median lobe distinctly sclerotized, S-shaped near narrow tubular apex, upcurved and incurved (Figs. 2a, 4a), together with the three black distal spines appearing hook like (Figs. 2a–b, 4a); outer lobe shorter than median lobe, slender and heavily sclerotized, apical portion fused with median lobe, apex with three spines, with apex of median lobe seemingly forcep-like (Fig. 2e).
