A new species of Echinogammarus from Algerian fresh waters, Echinogammarus haraktis n. sp. (Peracarida, Amphipoda)

Samplings in the area of Oum El Bouaghi yielded a new species, E. haraktis, belonging to the Echinogammarus simoni-group, in springs and wadis located on Mount EL Hamra in northeastern Algeria. The species is mainly characterised by the high number of long setae on the second antenna of both sexes, the lack of long setae on the basal segment of pereiopod 7 and on the exopodal segment of the uropod 3, and a much reduced second exopodal segment of uropod 3.
