Diagnostic description
Holotype, male (Fig. 48a). Length 3.23 mm. Color black; tibiae and antenna ferruginous. Body elongate; in dorsal aspect and in profile with distinct constriction between pronotum and elytron. Rostrum basally with distinct median and pair of submedian carinae, in apical ¼ relatively smooth; in front of eye sparsely squamose. Pronotum densely punctate with large punctures, interspaces smaller than puncture´s diameter. Elytra dorsally with striae deeply incised, intervals with 1–2 rows of punctures; laterally striae impressed as fine lines, strial punctures deep. Femora edentate. Profemur in basal third posteriorly with callus. Metafemur subapically without stridulatory patch. Abdominal ventrites 1–2 concave. Aedeagus (Fig. 48b) apically bluntly angulate, with pair of stout setae; body flattened, sides diverging to shortly before apex; ductus ejaculatorius without bulbus. Intraspecific variation.
