Rhinophores auriculate, oral tentacles lobiform and foot corners rounded. Cerata are arranged in about 13 oblique rows with 2-3 cerata in each row. The inside of each ceras has a leaf-like pattern of weakly ridged veins. There is a black median band on the body which passes on to the head. The cerata are green with black tips. Baba compares this species with his A. orientalis (Baba, 1949) but considers they are different - A. orientalis having brown not black markings, and much stronger venation on the cerata.
