Type locality. Korea .

Description. Body elongate, robust; head distinctly narrower than pronotum; crown medially wider than eyes, uniform to slightly produced at middle ( Figs. 4–5 ). Eyes long, ovoid; ocelli absent, distinct vestiges present as paired pits on face well ventrad of crown margin, closer to eyes than to each other ( Figs. 6–7 ). Pronotum broadened compared to head and scutellum, widened posteriorly, anterior margin of pronotum between eyes strongly produced, at hind margin excavated, on side rounded ( Figs. 6–7 ). Face longer than broad, in profile rather convex, weekly depressed. Anteclypeus broad at base, projecting beyond margin of gena; frontal suture reaching ocellar pits; rostrum tapered ( Figs. 6–7 ). Forewing more or less parallel sided, apical part rounded, without closed anteapical cells, R with two branches originating distad of mid-length, not divergent posteriorly, M with anterior branch straight ( Fig. 9 ). Hindwing with submarginal vein complete but weakly developed along costal margin ( Fig. 10 ). Front femur with dorsoapical pair of macrosetae; AM1 large, on ventral margin; intercalary row with 8–9 setae; tibia row AV with 8 macrosetae ( Fig. 16 ). Middle femur without PD; tibia without preapical macrosetae. Hind femur macrosetae 2+1+1; tibial chaetotaxy AD: 18–19, PD: 11–12, AV: 4–5, PV: 32–36 smaller basal and 12–14 larger distal setae, with api- cal transverse row of 6–7spines; hind basitarsus as long as tarsomeres II and III combined, subtriangularly pointed apically, with dorsoapical pair of macrosetae and a row of 5 smaller ventral setae ( Figs. 17–19 ).

Male genitalia. Pygofer lobe triangular, appendages absent, with group of long setae at apex ( Fig. 8 ). Subgenital plate with longitudinal row of strong macrosetae. Genital valve large, with median longitudinal ridge on inside. Style elongate and narrowed distally, without preapical lobe, with long sickle-shaped apex ( Fig. 14 ). Connective poorly sclerotized, I-shaped ( Fig. 15 ). Aedeagus with dorsal apodeme well developed; aedeagal shaft moderately long, compressed, shaft parallel-sided in lateral view, narrowed towards apex in posterior view, longer than preatrium, with small subapical process, apex with asymmetrical long process extended basolaterad; gonopore preapical on posterior surface ( Figs. 12–13 ).
