Gammarus baysali sp. nov., a new freshwater amphipod species from Turkey (Amphipoda: Gammaridae)

A new species of freshwater amphipod, Gammarus baysali sp. nov., collected from Cumayanı Cave (Zonguldak Province, Turkey) is described and illustrated. The new species belongs to the Gammarus pulex-group. The most discriminant characters of this species are the minute eyes, densely setose fifth peduncle and flagellar segments of antenna 2, elongated pereopods, and setose anterior margins of pereopod 5 to 7. Additionally, the palp of right maxilla 1 has 4 setae along its outer margin. A detailed morphological description and illustrations of the new species are provided, and differences from related species are discussed.
