Schizidium Tiberianum
''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 The telson () is the hindmost division of the body of an arthropod. Depending on the definition, the telson is either considered to be the final segment (biology), segment of the arthropod body, or an additional division that is not a true segm ... 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 spe ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

''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. Species ''Schizidium'' contains the following species: * '' Schizidium aegaeum'' (Sfenthouarkis, 1995) * '' Schizidium album'' ...
