Description
editIt 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.[2][3] The first joint of the antenna is remarkably small,[4] being only about half as long as the second.[3]
Ecology
editThe 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.[2]
