| Summary: | Notothenioid fish of the artedidraconid genus Artedidraco are a little studied, component of the bottom fauna on the Antarctic continental shelf. Trawling in the south-western Ross Sea, especially in shallow areas with sponge beds, yielded a collection of 65 specimens of Artedidraco . These included all four species occurring in the Ross Sea as well as a new species. The new species Artedidraco glareobarbatus is described and illustrated. This species is most similar to A. orianae , but is distinguished by barbel morphology, by higher counts for dorsal rays and vertebrae, by lower counts for upper lateral-line scales and by colour pattern and visceral anatomy. A distinctive spotted colour morph of A. shackletoni is also documented and compared with the typical barred morph. Depth distribution and meristic variation among species of Artedidraco are summarized, and a taxonomic key to the six species is provided. |
