Diagnosis

Frons with a more or less distinct median longitudinal carina extending from between the toruli to near the median ocellus, the sutures which define the scrobal area laterally tend to diverge ventrally, away from the median carina (Fig. 3 b); hind coxae usually finely reticulate on the externo-dorsal surface (Fig. 3 d).
