Uropodidae is a family of mites in the order Mesostigmata.
[1] As part of superfamily Uropodoidea, Uropodidae are tortoise-like mites with an oval to circular outline, and with armour both dorsally and ventrally.
They can be distinguished from other uropodoids by their chelicerae lacking a large, sclerotized node and their genital opening being in an intercoxal position.
It preferentially attacks pupae of soldier and male ants.
[5] This attachment is achieved using a pedicel of translucent material extruded from the mite's anus.
