Diagnostic description
Holotype, male (Fig. 67a). Length 2.40 mm. Color of legs and head ferruginous, remainder black. Body in dorsal aspect with marked constriction between pronotum and elytron; with distinct constriction in profile. Rostrum coarsely rugose-punctate, with median ridge and pair of indistinct submedian ridges; epistome with indistinct, transverse, subangulate ridge. Pronotum anterolaterally angularly projecting; with distinct subapical constriction; disk rugose-punctate, interspaces weakly microreticulate; punctures each with one suberect to recumbent scale becoming shorter towards base; with median ridge. Elytra with striae deeply impressed, each with row of slender suberect scales; intervals costate to carinate, almost nude, weakly microreticulate; interval 7 swollen subapically, laterally weakly projecting; sutural interval subapically simple. Femora edentate. Metafemur subapically with stridulatory patch and transverse ridge. Abdominal ventrite 5 in apical half slightly swollen, with median impression, punctate, sparsely setose. Penis (Fig. 67b) with body in profile moderately curved; in dorsal aspect sides subparallel; apex with median, acute triangular extension; transfer apparatus flagelliform, slightly shorter than body; apodemes 2.0 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.28–2.65 mm. Color of body black to dark ferruginous. Female rostrum dorsally with longitudinal furrows; epistome simple. Pronotum with anterolateral knobs rounded, or more distinct and angularly projecting, especially in females. Female abdominal ventrite 5 flat.
