Carapace, pereon and pleon with no setae, anterior margin serrate. Carapace dorsal crest serrated. Pereopod 1 without serrate carinae on carpus and propodus. Telson with 4 pairs lateral setae, with 3 long terminal setae. Adult male antennal flagellum moderate, reaching past pereon but not to end of pleon. Telson with 5 pairs of lateral setae. Depth . 2370–3550 m. Distribution . Canada Basin, Arctic Ocean, 79– 82°N, 127– 129°W. Remarks . This species is the most similar to Hemilamprops , in that the accessory flagellum is greater than 0.5 the length of the main flagellum and the telson is more than 0.5 the length of the uropod peduncles, although less than 0.7 the peduncle length. However, the robust pereopod 1 with a group of long setae on the dactylus is distinctly Chalarostlyis , and not like the slender pereopod 1 found in Hemilamprops . The species can be distinguished from all other Chalarostylis by the combination of the serrate anterior margin of the carapace, the accessory flagellum more than 0.5 the length of the main flagellum, and the telson more than 0.5 the length of the uropod. There is a discrepancy in the length of the male antenna in Vassilenko’s figure (Vassilenko 1990). In Figure 3, the antenna is figured with the flagellum about 4.0 the length of the fifth peduncle article, similar to the proportions seen in C. elegans , but in the full body illustration (Fig. 1, Vassilenko 1988) the flagellum appears to be much longer, and it is possible that this is an artifact of the position of the specimen. The full body seems to suggest that the male antenna is longer than that seen in other Chalarostylis males, but the individual figure of the male antenna resembles the other Chalarostylis males in having a flagellum that is short, ...
