Diagnosis. Body elongate ( Fig. 3 ), larger species; outline distinctly constricted between pronotum and elytra; pronotum without median longitudinal line; lateral margins of pronotum feebly explanate; strial punctures small, covered by pubescence; scutellum longer than wide, subpentagonal with anterior margin convex. Ninth segment with spiculum gastrale as in Fig. 16 . Aedeagus ( Figs. 13–15 ): in ventral/dorsal view phallobase parallel-sided in apical 0.6, base subacuminate; parameres ca. 1.2 times as long as phallobase, wide, parallel-sided, slightly constricted in apical 0.2 and abruptly narrowed near subacuminate apex; median lobe slightly longer than parameres, parallelsided, apex subacuminate; fibula indistinct; ventral sac robust, finely sculptured in apical portion; in lateral view parameres curved apically, widened prebasally, median lobe very narrow, curved, widened near base. Ovipositor ( Figs. 36, 37 ) with terminal segment relatively longer than in other species, cylindrical, bearing several types of sensilla; preterminal segment only 3.7 times as long as terminal segment, with pair of distinct sensilla; basal segment ca. 1.4 times as long as preterminal and distal segments combined, fulcrum ventrale slightly curved.

Distribution. Malaysia (Sabah, Sarawak), Brunei.
