Zusammenfassung: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.
