Differs from Acestrocephalus sardina and Acestrocephalus nigrifasciatus by having smaller eye and fewer maxillary teeth (30-38 vs. 40-46). Can be separated from Acestrocephalus acutus by possessing only scattered dark chromatophores instead of the typical oblong dark blotch on the caudal-fin base of that species and the first pleural rib, the cavity anterior to it and the obliquusinferioris muscle visible (vs. entirely covered by the fibers of the obliquus superioris muscle in Acestrocephalus acutus (Ref. 75890).Description: Dorsal fin ii,9; Anal fin iv,32-36; Pectoral fin i+11-15; Pelvic fin i+7 (Ref. 75890).
