Pronotum coarsely punctate, reticulate-costate, with median costa; with sparse, recumbent scales. Elytra with striae dorsally deeply incised, laterally marked by rows of coarse punctures; intervals markedly costate, dorsally flattened, with rows of punctures; sutural interval basally slightly widened laterad; each puncture containing small recumbent scale; elytral apex subtruncate. Femora with simple anteroventral ridge. Metafemur subapically with stridulatory patch. Abdominal ventrite 5 coarsely punctate, with sparse subrecumbent scales. Penis (Fig. 91b) with sides of body subparallel, with shallow constriction at middle, before apex sides slightly swollen; apex with median angulate extension; transfer apparatus with thick median rod 1.7 × as long as body; median rod projecting basad further than apicad; apodemes 2.8 × as long as body; ductus ejaculatorius without bulbus.
