S. Renahy .</p><p>Chaetogammarus can easily be distinguished from Gammarus and Dikerogammarus by the morphology of the third uropod and the first and second urosome segments. In the genus Dikerogammarus and Chaetogammarus, the inner ramus of the third uropod is very short (Fig. 2 B), whereas it is well developed in Gammarus . Furthermore, Chaetogammarus and Gammarus lack the paired dorsal protuberances bearing spines on the first and second urosome segments (Fig. 2 A), a characteristic feature of Dikerogammarus species.</p><p>Compared with C. ischnus, C. trichiatus is characterized by a third uropod densely covered with recurved setae (Fig. 2 B). In females of C. trichiatus, these recurved setae are at least densely developed at the apex of the third uropod.</p><p>The identification key provided below covers amphipod taxa commonly encountered in Lake Geneva but does not include Chelicorophium species.</p><p>Identification key</p></div>	https://treatment.plazi.org/id/5F3698E9047E5802A1487623678DD54C	Public Domain	No known copyright restrictions apply.
