A new species of Artedidraco (Pisces: Artedidraconidae) from the Weddell Sea, Antarctica

The Artedidraconidae is the most speciose of the five Antarctic notothenioid families. Bottom trawling in the Weddell Sea has yielded a new species herein described from two specimens, a juvenile and an immature female. Artedidraco longibarbatus differs from other species of Artedidraco in having a...

description The Artedidraconidae is the most speciose of the five Antarctic notothenioid families. Bottom trawling in the Weddell Sea has yielded a new species herein described from two specimens, a juvenile and an immature female. Artedidraco longibarbatus differs from other species of Artedidraco in having a much longer mental barbel (about 25 % SL vs. 4–14 % SL). While recent genetic studies indicate that Artedidraco is paraphyletic, we choose to follow traditional taxonomy based on morphology. Selected meristic data and a key to the seven species of Artedidraco are provided.
