Pronotum coarsely punctate, reticulate-costate, with median costa; with sparse, recumbent scales. Elytra with dense, confused punctation; intervals flat, each with row of punctures; each puncture containing small recumbent scale; elytral apex subtruncate. Femora with simple anteroventral ridge, crenate in metafemur. Metafemur subapically with stridulatory patch. Abdominal ventrite 5 coarsely punctate, with sparse suberect scales. Penis (Fig. 49b) with sides of body subparallel; apex with median angulate extension; transfer apparatus with flagelliform median rod forming almost full coil; median rod projecting basad further than apicad, ca 2.7 × as long as body; apodemes 3.4 × as long as body; ductus ejaculatorius without bulbus.
