Gammarid amphipods (Crustacea) in Norway, with a key to species. Fauna Norwegica 39:12-25. Comments: Distinctive small (length max 12 mm in males, 10 mm in females) and striped Gammarus-species, easy to distinguish from other species alive due to transverse dark bands on back and on the sides forming a zipper-like pattern, back and side bands not " in line". Males with numerous long, curved, thin hairs on 2nd antenna and pereopods 3-4 and 6-7 (last big legs). Urosome segments 1-3 with only short stout spines. Females not so distinct without distinct setation. Identification: Lincoln (1979), Vader and Tandberg (2019) |

Comments: Jazdzewskiet al (2004) define it as oligohaline species Daunys & Zettler (2006) observed a tolerance range between 0-25 PSU. Tolerates almost fresh water. |
