| Abstract |
After a more detailed investigation of its skeletal anatomy, the Japanese Bathyraja tobitukai (Hiyama, 1940) is removed from its genus and is considered as a species of Notoraja Ishiyama, 1958. The latter taxon is elevated to generic rank from its original status as a subgenus of Bathyraja Ishiyama, 1958. A single early adolescent specimen, obtained in 1980 during the MUSORSTOM 2 expedition from deep water off the northwestern Philippines, is described as the holotype of Notoraja subtilispinosa sp. nov. which is the second species of this, so far, monotypic genus. |
