Journal of ichthyology Vol. 62, № 2. P. 316-319Abstract: Eustomias securicula sp. nov. from the area of the Northwestern (Emperor) seamount chain, the second species of the subgenus Biradiostomias known outside the Atlantic Ocean, has been described. It differs well from the only previously known Pacific species, E. ioani, in the structure of the terminal part of the chin barbel, the smaller number of branchiostegal photophores, and the absence of dorsal subcutaneous spots. The new species has not been found to be closely related to any of the Atlantic representatives of the subgenus. The specific range of the subgenus Biradiostomias (Atlantic, North Pacific) may be due to the prochoresis of the ancestral forms of the Pacific species through the Strait of Panama.
