Status Stebbing (1906) designated the nom. nov., N. sarsi, to a species previously recorded by both Boeck (1871) and Sars (1890) as N. quadrimanus. This decision was based on three gnathopod 1 characters, each of which had states in N. sarsi that he considered to be different from those of N. quadrimanus (Bate and Westwood). The ischium, according to Stebbing, is relatively longer in N. quadrimanus than in N. sarsi, the carpal process is acute in N. sarsi and obtuse in N. quadrimanus, and the inner margin of the dactylus of N. quadrimanus is completely smooth, while that of N. sarsi is “strongly serrate”. As Stebbing based his descriptions on previous descriptions and illustrations by Boeck (1871) and Sars (1890), no type material of Normanion sarsi was designated for comparative purposes. In the same publication, Stebbing placed N. amblyops in the synonymy of N. quadrimanus (Bate & Westwood). Hence, Stebbing may not have actually compared his
N. sarsi with the true N. quadrimanus, but rather with N. amblyops (herein considered a valid species). This would account for the difference, noted by Stebbing, in relative length of the ischium between N. sarsi and N. quadrimanus, as the ischium is slightly longer in N. amblyops than in any of its congeners. In the material examined by us, no differences were found in the form of the gnathopod 1 carpus between any of the species. The ‘serrate’ dactylus is found in both N. quadrimanus and N. ruffoi, and to a lesser degree, in N. chevreuxi. Thus, it appears to be a variable character within species. It seems then, that Normanion sarsi Stebbing is not a valid species, but is a junior synonym of N. quadrimanus (Bate & Westwood). [details]
