Genus UGYOPS Guerin-Meneville

Ugyops Guerin-Meneville , Zoologie, Insectes, 477, 1834. Haplotype, Ugyops percheronii Guerin-Meneville.

This is a genus of the subfamily Asiracinae , with the calcar subulate or awl-like. Ugyops belongs to a group of genera in this subfamily which has elongate antennae with the first and second segments about equal and the mesonotum quinquecarinate; the median facial carina is very variable, being sometimes single, sometimes forked at the middle of the face or below and sometimes forked from the clypeal border. The genitalia of the various species are frequently quite different. I suspect that this genus represents a complex of genera, but, until more material is available, it is not possible to distinguish the different forms.

Thirty-nine species have been described from various parts of the world, chiefly from the Eastern Hemisphere. In the Western Hemisphere, there are only two known species, both from Puerto Rico. In the Eastern Hemisphere, species have been recorded from the Seychelles, eastward across the Malay Peninsula to Indo-China, northward to Japan, southward through the larger East Indian islands, and New Guinea, south to Lord Howe Island, and eastward to Fiji and Samoa. They seem to be strangely absent from India, Ceylon, Australia, and the Hawaiian Islands. There are two species of this interesting genus in the present collection.
