Diagnosis. Male: Tergum IX deeply excavated posterio-medially, tergum X without knobs or spines; apex of sternum IX relatively short. Epiproct simple, hook-shaped; cercus short but with apical spine. Female: Sternum VII rectangular, without any modification, not fused to sternum VIII. Median sclerites on sternum VIII are large and brown, posterio-medially pointed, basally with a sinuous wrinkle; laterally they are connected to a pair of small sclerites.
