Subquadrate, about as wide as long, widest across eyes, slightly narrower than pronotum; eyes slightly large and prominent, about 1.3–1.4 times as long as temples; gular sutures moderately separated; infraorbital carina complete; diverged basally; cervical carina complete. Antennae (Fig. 7 A) long and slender; antennomeres 1–3 elongate, 1 longest, 2 about as long as 3, 4–10 quadrate to subquadrate, 11 about as long as 1, about as long as preceding two combined. Mouthparts. Labrum transverse, slightly emarginate in anterior margin, with ε-sensillum and about 9 macrosetae on each side of midline; epipharynx with several sensilla, including 2 lateral sensory rows on each side of midline; α-sensillum long and setaceous, about 2.0 times as long as εsensillum, β- and γ-sensilla very short. Mandibles asymmetrical, subtriangular, decurved and pointed apically, about 1.5–1.6 times as long as basal width; minute denticles present in molar region; right one with small internal tooth, internal margin slightly serrulate; prostheca developed, composited three portions.

Labium with ligula divided into 2 lobes in basal half; prementum with two medial setae widely separated; two basal pores moderately separated, about 1.0–2.0 times width of basal pore; several medial pseudopores, 1 setal pore and 2 real pores present on each side of midline; labial palpus with many setulae; palpomere 1 largest, about 1.7–1.9 times as long as wide, γ-setula contiguous with b-seta, 2 shortest, about 1.2–1.4 times as long as wide, 3 subparallel-sided and about as long as 1, about 3.0–3.5 times as long as wide. Mentum trapezoidal, anterior margin slightly emarginate; v-seta very short, close to u-seta. Thorax. Pronotum slightly transverse, approximately 1.1–1.2 times as wide as long, widest in apical third to half; hypomera fully visible in lateral aspect. Metanotal scutum with 2 long setae and about 3–4 relatively short setae on each side of midline. Mesocoxal cavities narrowly separated, mesoventral process pointed at apex, slightly longer than isthmus and metaventral process combined; isthmus slightly longer than metaventral process. Elytra transverse, slightly wider than pronotum; elytron approximately 1.5–1.6 times as long as wide, pubescence directed posteriorly and posterolaterally; postero-lateral margin almost straight; hind wings fully developed, flabellum composed of about 9–11 long setose lobes. Legs. Slender and long, with pubescence and macrosetae; meso- and metatibiae with different length of two spurs at apex; tarsal formula 4-5-5, length ratio of tarsomeres 33:37:39:89 (protarsus); 39:48:48:45:89 (mesotarsus); 71:69:61:56:106 (metatarsus); one empodial seta present, slightly shorter than claw.

Aedeagus. Median lobe (Figs. 7 F–G) narrowly ovate and widest in basal fourth, apical process constricted basally and convergent at apex in ventral aspect; internal sac elongate. Apical lobe of paramerites (Fig. 7 H) with four setae; a-seta longest, c- and d-setae shorter than b-seta, close together and positioned apically. Spermatheca. Bursa globular apically, with small umbilicus; duct simply coiled (Fig. 7 I).
