Operclipygus
Operclipygus is a genus of hister beetles (family Histeridae) containing approximately 177 described species. The genus name refers to the clamshell-like appearance of the pygidium (rear end). A 2013 systematic revision by Caterino and Tishechkin described 138 new species from Central and South America, increasing the genus size more than sixfold. These beetles are small, round, and predominantly black, with ecological importance as predators of insect larvae.
