Subterranean Philosciidae from Spain with the description of a new genus and two new species (Crustacea, Isopoda, Oniscidea)

A new genus and two new species of terrestrial cave-dwelling isopods from the eastern Iberian Peninsula and the Balearic Islands, belonging to the family Philosciidae Kinahan, 1857, are described and fully illustrated. Iberoscia gen. nov. is erected to accommodate Iberoscia zaragozai sp. nov. from Catalonia, Murcia and the Valencian Community. Furthermore, the genus Paractenoscia Taiti & Rossano, 2015 is recorded for the first time in the Ibero-Balearic region with the description of a new species from Ibiza (Balearic Islands).

Moreover, the male of Anaphiloscia simoni Racovitza, 1907, is illustrated for the first time based on topotypical specimens from Mallorca, and Anaphiloscia sicula Arcangeli, 1934, is proposed here as a subjective junior synonym of this species. Finally, the monotypic genus Parachaetophiloscia Cruz & Dalens, 1990, is revised and proposed as a subjective junior synonym of Chaetophiloscia Verhoeff, 1908.
