Diagnostic description
Holotype, male (Fig. 45a). Length 2.86 mm. Color of legs and antennae ferruginous except protarsus black; remainder black. Body elongate; in dorsal aspect with marked constriction between pronotum and elytron; in profile dorsally flat, apically convex. Rostrum with median and pair of submedian ridges; intervening furrows each with sparse row of erect piliform scales; epistome simple. Pronotum laterally with subapical constriction; disk coarsely punctate to scabrous; submedially each puncture containing elongate white scale, towards sides with minute setae; with median ridge. Elytra with striae indistinct; intervals flat; surface dull, microreticulate, microgranulate; with sparse minute punctures and scattered lanceolate scales; interval 7 in apical third forming sharp lateral edge; sutural interval at apex swollen, forming pair of rounded apical protrusions. Femora edentate; anteroventral ridge crenulate. Metafemur subapically with stridulatory patch. Dorsal edge of pro- and metatibia subbasally simple, mesotibia subbasally with angulation extended as acute tooth. Tarsomere 3 of protarsus markedly larger than of mesotarsus. Abdominal ventrite 5 with shallow concave pit, apically with dense short suberect setae. Penis (Fig. 45b) with sides of body subparallel; apex medially pointed; transfer apparatus flagelliform, 4.0 × longer than body; apodemes 2.8 × as long as body; ductus ejaculatorius without bulbus.
