Taxonomic Remarks
Provisionally retained as valid but treated as junior synonym of A. hyperborea by Weigmann (2016, Ref. 106604) due to strong morphological similarity and preliminary molecular data. Further work is needed to resolve this issue (Ref. 118749).

Lacks large thorns on anterior margins and mid posterior parts of pectorals and on either side of mid-dorsal ridge on the disc. Upper surface plain light brown, either grayish or of chocolate hue, darker along margins of fins. Lower surface brownish gray, grayish white or perhaps pure white (Ref. 6902).
Body shape (shape guide): other.
在前緣上缺乏大的刺與在胸鰭的較後面的部分之中與在體盤上的背部中央脊的任一側邊上。 上表皮純淡褐色, 或淺灰色的或巧克力色, 比較深色的沿著鰭的邊緣。 下表面灰褐色, 白灰色或也許全白色的.(參考文獻 6902)

Benthic (Ref. 58426). Deep-water species. Prefers higher temperatures. Feeds on small fishes and crustaceans (Ref. 6902). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Maximum depth reported taken from Ref. 117245. It may be captured as by-catch in deep water fisheries, but due to its depth preference, it is less likely to be vulnerable (Ref. 117245).
