| Abstract: | Paraliparis wakataka sp. nov. is described based on seven type specimens and three non-types collected off the Pacific coast of the Tohoku region, northern Japan (483–752 m depth). The new species is morphologically similar to Paraliparis meridionalis Kido 1985, and Paraliparis hokuto Murasaki, Takami and Fukui 2019, distributed off the Pacific coast of southern Japan, but differs from both and other congeners in the following combination of characters: vertebrae 62–64; dorsal-fin rays 54–57; anal-fin rays 50–53; pectoral-fin rays 18–21; caudal-fin rays 7 or 8; lower jaw included, mandibular tooth plates entirely within posterior margin of premaxillary tooth plates; teeth on both jaws simple, forming bands each with up to 6–10 teeth; chin pores paired, opening in a common pit; gill slit entirely above pectoral fin; proximal pectoral radials 3 or 4; pyloric caeca length ca. 30% head length; body semi-transparent to light blackish. A molecular analysis supported the validity of the new species. [ABSTRACT FROM AUTHOR] |
