Tip of lower jaw broadly rounded; a spot of black pigment often present on the underside of snout, at least in smaller individuals; tooth patches on parasphenoid and basibranchial bones more broadly oval in shape, average width/length 0.38 and 0.45, respectively; number of teeth in pharyngobranchial tooth patch usually 5-15 (Ref. 9828). Compared to A. argentea which has a yellow spot on the axil of the pectoral fin, in this species, there is none (Ref. 74924). |
