A new cave species of Deuteraphorura (Collembola: Onychiuridae) and redescription of four species of the genus from Italy

The description of a new species and the redescription of four species of the genus Deuteraphorura are given. Deuteraphorura caprelleana sp. nov. is characterized by the peculiar distribution of dorsal (32/033/33354) and ventral (3/011/3212) pseudocelli that allow to recognize it from the other congeneric species. Furthermore, four species, Deuteraphorura apuanica (Dallai, 1970), D. pseudobosnaria (Dallai, 1970), D. pseudoinsubraria (Dallai, 1970) and D. pseudoghidinii (Dallai, 1969), are redescribed based on type and new topotypic material to furnish the description of some characters, especially concerning the chaetotaxy, not considered in the original description. A proposed key to the italian species is also reported.
