Phthiracaroidea
ptyctimous mites
Phthiracaroidea is a superfamily of oribatid mites (ptyctimous mites) characterized by a unique defensive mechanism: the ability to retract their legs and chelicerae into a protective cavity and close the body using a ventral scissure. The group includes families Phthiracaridae, Synichotritiidae, and related taxa. Members are primarily soil-dwelling decomposers found in leaf litter and humus across diverse geographic regions including the Palearctic and Southeast Asia.
