Overview
The New World subfamily Stegaspidinae includes two tribes (Stegaspidini and Microcentrini) and a few taxa of uncertain position. The unplaced taxa, all from the West Indies, include the extant genera Antillotolania, Borinctolania, and Deiroderes, as well as undescribed fossils from Dominican amber. The diversity of pronotal forms found in this subfamily is extraordinary.
