FURTHER DISCOVERY OF NEW OR PARTIALLY KNOWN TAXA OF THE GENUS NIPHARGUS SCHIÖDTE, 1849 (FAM. NIPHARGIDAE) IN GREECE (CONTRIBUTION TO THE KNOWLEDGE OF THE AMPHIPODA 302)

The new subterranean subspecies of the genus Niphargus Schiödte, 1849 (Amphipoda Gammaridea, Niphargidae), N. (Orniphargus) lourensis skirosi, ssp. n. is described and figured from the underground waters of Skiros Island in the Aegean Sea (Greece), taxon rather similar to the nominal species N.(Orniphargus) lourensis Fišer et al. 2006 described and known based on one single specimen from Epirus region of Greece only. Niphargus (Orniphargus) lindbergi S. Karaman 1956, described and known based on single specimen from Attica region of Greece only (Draconera Cave), is established in Thessaly region also [spring on main road Lamia-Larissa (=Laritza) in Central Greece], and new taxonomical data of this species from both localities are presented. The presented data put some more lights on the taxonomical position of these taxa. The mentioned taxa, Niphargus lourensis, skirosi and lindbergi belong to the subgenus Orniphargus S. Kar. 1950.
