Pergamasus
Pergamasus is a genus of predatory mites in the family Parasitidae, comprising approximately 70 described species distributed across the Northern Hemisphere. These soil-dwelling gamasid mites inhabit forest litter, mosses, and upper soil layers, where they function as generalist predators of small invertebrates. Several species have been documented as predators of tick nymphs, suggesting potential ecological significance in tick population control. The genus exhibits notable morphological diversity, with species groups defined primarily by male genital and leg characters.
