Elytra with striae deeply impressed, intervals costate to subcarinate; striae and intervals each with row of subrecumbent, short bristles; interval 7 swollen subapically, laterally projecting. Femora edentate. Metafemur subapically with stridulatory patch and transverse rows of denticles. Abdominal ventrite 5 somewhat swollen, at middle with shallow impression, sparsely setose. Penis (Fig. 40b) with body flattened, sides subparallel; apex subangulate; transfer apparatus spiniform, subequal to body; ductus ejaculatorius without bulbus. Intraspecific variation.
