Antennae 16-segmented not very flattened. Frontal ridge with longitudinal furrow narrowed below median ocellus and then divergent toward the clypeus. Pronotum with the carina arcuate and interrupted by three sulci. Hind angle of the pronotum rounded. Anterior angle pointed. In lateral view the principal transverse sulcus between prozona and metazona clearly incised. Prosternal process trapezoidal from below. Mesosternal lobes are approximately equal width than long. Mesosternal space 2.0 times wider than long. Sub-brachypterous with the tegmina reaching the 5 th abdominal tergite and the epiproct visible. Hind wing with de 2 nd anal vein curved. Hind tibiae with double rows of several stout spines and a pair of larger stout spurs on each side. In dorsal view, the male epiproct is rectangular, pointed on the hind margin and with a longitudinal furrow; cerci slender, pointed and longer than epiproct.

Ovipositor valves cream coloured, stout with slightly curved black tips. Sub-genital plate rectangular, with a triangular lobe in the middle.
