came from three isolated montane rainforest habitats, and each population shows a striking morphological divergence that might indicate several species are involved. This character variation include overall body size, the shape of the sides of the head, the presence or absence of a blunt angle on the middle of the convex anteromedial clypeal margin, and the strength of body sculpture. However, gradations in body size and sculpture also appear among populations within the distributional range of the species and we consider them to belong to a single variable species.
