摘要

A new species Pogonophryne minor sp. n. based on materials of Antarctic expeditions on research vessels Chatyr-Dag and Ob to the East Antarctica is described. The type specimens of the new species were caught in the Mawson and Davis seas at depths 420540 m. The comparison of the new species with two other species of the marmorata group of the genus Pogonophryne: P. platypogon Eakin, 1988 and the most closely related P. marmorata Norman, 1938 is provided.
