Argyripnus boreopacificus sp. nova, a new species of hatchetfishes (Sternoptychidae) from the subtropical Northwestern Pacific

Resumo

A new species of the genus Argyripnus is described from the underwater elevations of the Northwestern Pacific. The species is most similar to A. hulleyi from the western Indian Ocean, but it differs in a larger number of rays of the dorsal and pectoral fins, a slightly larger number of photophores in the ventral row, and several other characters. The type series of the species is the most northern record of the representatives of the genus in the Pacific Ocean.
