Description

Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 28.

The seven known species of Pogonophyrne are described and keyed. The mental barbel shows some variability, especially in Pogonophryne permitini. The genus is divided into two groups, one of three species, (P. scotti, P. dolichobranchiata, and P. phyllopogon) with no dorsal spots on the head and a low number of vertebrae (35-37) and rays(24-26) in the second dorsal fin and the other of four species (P. marmorata, P. barsukovi, P. permitini, and P. mentella), with dorsal spots on the head and a higher number of vertebrae (36-38) and rays (25-29) in the second dorsal fin. Most of the species appear to have circumpolar distributions, five being known from both East and West Antarctica. Only P. phyllopogon is known from just one locality and was not present in the new material. Several very small and very large specimens (the latter with damaged barbels) were not identified but are described.
