Ocypus
Ocypus is a genus of rove beetles in the subfamily Staphylininae, containing approximately 176 described species distributed across the Palearctic, Nearctic, and Oriental regions. The genus includes the well-known Ocypus olens (devil's coach-horse beetle), a large, predatory species with documented potential for biological control of pest snails. Several species have been introduced outside their native ranges, including O. nitens, which has established in North America and shown rapid range expansion. The genus exhibits considerable diversity in China, with numerous species described from Sichuan, Gansu, Yunnan, and other provinces.
