Cephalopholis polyspila is described as a new species of serranid fish of the subfamily Epinephelinae from Sumatra and the Andaman Sea, off southwestern Thailand. It is similar to C. microprion (Bleeker), differing in having small blue spots on the head, body, and fins instead of just the head and thorax: in having 16 or 17 (more often 17) instead of 15 or 16 (more often 16) pectoral rays: in having small scales dorsally in the snout extending anterior to the nostrils (not present in C. microprion), a more elongate body on average, shorter pectoral fins, and in attaining larger size (188 mm SL, compared to 145 mm SL for C. microprion). It has also been confused with the blue-spotted C. cyanostigma (Valenciennes), differing in life color, in usually having 15 soft dorsal rays (strongly modal 16 rays in cyanostigma), and in its smaller size (cyanostigma to at least 234 mm SL).
