Rostrum reaching beyond posterior margin of middle coxae or to anterior margin of hind coxae or beyond. Pronotum slightly wider than mesonotum. Mesonotum with a pair of paramedian, juxtaposed, black, obconical spots and a pair of black to black-brown lateral sigillae. Fore femora with four spines along lower ridge. Tegmina and wings hyaline, wings with four apical areas. Male operculum sickle-shaped and with adjacent setae, margins and apical third with long setae. Timbal with 6-7 ribs and faint intercalary ribs.
