Abstract
Argyripnus electronus sp.nov. collected from the Sala y Gomez submarine ridge in the eastern South Pacific is most similar to A. atlanticus Maul from the Atlantic Ocean and unnamed Argyripnus sp.of Yamamoto (1982) from the Kyushu-Palau ridge. It differs from both these species in having much more photophores in VAV+AC and IC series, in lower body depth and in other characters.
