Family Niphargidae

The Niphargidae is a large family of freshwater Amphipods living almost exclusively in subterranean waters of the Western Palearctic. The original lists of genera and species (nine accepted genera; 274 accepted species) in the WAD were outdated and incomplete. The data grant allowed one genus ( Niphargopsis Chevreux, 1922) to be moved to Niphargus SchiÖdte, 1949, and two new genera ( Exniphargus G. S. Karaman, 2016, Niphargobatoides G. S. Karaman, 2016) were added; 111 subspecies were raised to species rank; 34 new species were added; two species were moved into synonymy. The original names for 377 taxa (species and subspecies) were documented and missing original description sources were scanned and linked (Fišer & Horton, 2015). The authorities were completed for all taxa, and years of publication were revised where necessary. Type or neotype localities for 379 taxa were documented and information on the deposition of type, lectotype or neotype material was documented for 91 taxa. The etymology for 219 taxa was documented. The environmental requirements were revised for all species. The distribution for 379 taxa was documented at the level of country and FADA biogeographical regions (Fišer & Horton, 2015). This revision was a major improvement to the taxonomic backbone and eased all subsequent work on the group.
