Diagnosis. Body elongate ( Fig. 1 ), ca. 2.00–2.15 times as long as wide (CL/EW), length 3.10–3.70 mm (CL), maximum width 1.50–1.80 mm (EW); color brown to dark brown; median pronotal groove or line absent, lateral pronotal margins strongly explanate; elytral intervals densely setose, very slightly elevated; elytral striae well demarcated, strial punctures smaller on disc, larger on sides. Scutellum as long as wide, subhexagonal. Ninth segments with spiculum gastrale as in Fig. 12 . Aedeagus ( Figs. 9–11 ): in ventral/dorsal view, phallobase short and wide, with base without distinct projection; parameres almost 1.5 times as long as phallobase, wide, with subrounded apex; median lobe slightly longer than parameres, narrowed in apical 0.4, widened in basal 0.6, constricted near base, apex rounded; fibula indistinct; ventral sac robust, finely sculptured in apical portion; in lateral view parameres subparallel, narrowed apically; median lobe narrow, sinuate, abruptly widened above base. Ovipositor ( Figs. 34, 35 ) with terminal segment short, cylindrical, bearing several types of sensilla; preterminal segment elongate 9.1 times as long as terminal segment, apically with pair of distinct sensilla; basal segment almost 1.3 times as long as preterminal and distal segments combined, fulcrum ventrale finely curved.

Distribution. Known from several localities in the Malaysian Peninsula.
