    Formerly "Democephalus" granulatus. Moved to new genus by M. Beebe (1990) in his unpublished thesis. Has distinct ridges eyes, long spines in the librigenae. The thorax has a granulose surface; the pygidium is semicircular.

    Only upload images of one specimen per entry.  You can upload multiple images of a single specimen.  (Make separate entries for different specimens of the same species.) If you think it appropriate, include an image with arrows or other indicators pointing to diagnostic features that characterize the Family/Genus/species.
