A new species of notothenioid fish, Pogonophryne cerebropogon n. sp., is described from the Ross Sea, Antarctica. The new species belongs to the dorsally spotted group of the genus and is characterized by having a brainlike terminal expansion on the long, bicolored mental barbel (23% SL, about twice as long as the barbels of other species with brainlike terminal expansions) and a very wide (7.6% SL vs about 4-7% SL for all other dorsally spotted species) interorbital region. This species has a greatly depressed head. The oral valves bear palmate papillae. The 7.6 m wide Marinovich Gulf Coast style trawl used in capturing this specimen was particularly effective compared to the small Blake trawls typically employed in the area.
