Pronotum with disk coarsely punctate; interspaces between punctures subglabrous, subequal to or smaller than punctures´ diameter; median line weakly costate. Elytra with striae marked by small punctures; each puncture bearing short subrecumbent seta; stria 8 near humerus with six larger punctures, externally bordered by costa; intervals subglabrous. Femora dentate; anteroventral ridges crenate, ending with acute tooth. Metafemur with indistinct posteroventral ridge bearing a second acute tooth; subapically with stridulatory patch.
