Schizidium is a genus of woodlice, found from Greece to Iran.
Description
It has a convex body, and is capable of volvation (rolling into a ball) without leaving fissures. It has small eyes with several ocelli. Its telson is triangular and its uropods are similar to those of Armadillidium. The first joint of the antenna is remarkably small, being only about half as long as the second.
Ecology
The species of the genus appear in three varieties: Fully epigeal (land-living) species, mostly moving around at night and hiding under stones during the daytime, these species are fully pigmented; endogeal species, which mostly live interstitially, are generally depigmented with reduced sizes and eyes, and cave-dwelling species with reduced or missing eyes, and generally depigmented. The latter two types do not occur outside of the Aegean Islands.
