Taxonomy of Alpioniscus (Illyrionethes): A. magnus and three new species from the Dinaric Karst (Isopoda: Oniscidea: Trichoniscidae).

ABSTRACT

Alpioniscus (Illyrionethes) is a widespread subgenus of Trichoniscidae in the Dinaric Karst with 15 nominal troglobiotic species. Here we redescribe Alpioniscus (Illyrionethes) magnus and describe three new species (A. lossinii n. sp., A. drazinai n. sp., and A. mandalinae n. sp.) restricted to coastal areas. As a result, 18 nominal Illyrionethes species are known from the Dinaric Karst.
