Restoration of the taxon Lycodes marisalbi, with notes on its disjunct Arctic distribution
Examination of a large number of Lycodes specimens from the Arctic Ocean showed that western Canadian Arctic (Beaufort Sea) specimens, hitherto identified as Lycodes pallidus Collett, 1878 are identical with Lycodes marisalbi Knipovich, 1906 from the White Sea. Both populations have a ventro‐medio‐l...

| Summary: | Examination of a large number of Lycodes specimens from the Arctic Ocean showed that western Canadian Arctic (Beaufort Sea) specimens, hitherto identified as Lycodes pallidus Collett, 1878 are identical with Lycodes marisalbi Knipovich, 1906 from the White Sea. Both populations have a ventro‐medio‐lateral lateral line system, not in accordance with the ventral and posterior medio‐lateral type of lateral line found in L. pallidus . Lycodes marisalbi , which has been regarded as a subspecies of L. pallidus since 1954, is hence restored as a valid taxon. A revised diagnosis, description and synonymy are given. The extended distribution range of L. marisalbi is probably disjunct (White Sea and Beaufort Sea), indicating a biogeographic pattern characterized by affinity to relatively shallow water with reduced salinity. Specimens from Franklin Bay (Beaufort Sea) with light vertical bars, previously assigned to Lycodes sagittarius McAllister, 1975 are here assigned to L. marisalbi , restricting L. sagittarius to include uniformly brown specimens only. |
