Rows on tail	no rows
Other melanophores on tail	tail with single melanophore
Peritoneum	with row of melanophores
Presence of a single large pigment patch, which expands during larval development, dorsolaterally on the peritoneum, and another patch laterally on the tail. Development is gradual and direct, with little additional pigmentation throughout the pelagic stage. Compared to A. bajacali, notochord flexion and fin ray development occur at a smaller size, the pigment patches are relatively smaller, and the total number of myomeres are fewer.
