Diagnosis

The frons is swollen posteriorly, the antennal ledges distinct and parallel to the hind margin of the ventral surface of the head, the antennal pits shallow and the maxillary plates narrow. The ventral surface of the head is separated from the dorsal surface by a sharp ridge. Dorsally the head is slightly rounded anteriorly, though not produced, and the ocelli occur just in front of the eyes. The anterior margin of the pronotum is parallel with the dorsal anterior margin of the head and is narrow laterally and somewhat declivous. The tegmina are evenly rounded apically and the venation is not reticulate. The hind tibiae are flattened, the outer edges bearing two rows of mobile spines mounted on slightly protuberant bases (Evans 1937).
