摘要

A new sparid species, Acanthopagrus pacificus, is described on the basis of a holotype, 6 paratypes, and 47 non-type specimens (64-348 mm in standard length [SL]), widely collected from the western Pacific. Acanthopagrus pacificus sp. nov. is most similar to A. berda in overall appearance of body with 3'/2; scale rows between the fifth dorsal fin base and lateral line. Acanthopagrus berda develops a distinct concavity of the ventral edge of the first two infraorbitals above the posterior part of upper jaw in specimens over ca. 13 cm SL, while A. pacificus sp. nov. has a generally straight infraorbital edge until 35 cm SL, and then, develops a moderate concavity of the ventral edge of the first two infraorbitals above the rear end of the maxilla. Acanthopagrus pacificus sp. nov. also differs from A. berda in having fewer total gill rakers (13-17, modally 15 vs. 15-19, modally 17 in A. berda), less deep body (mean depth 45% SL vs. mean 50% SL) and larger orbit diameter (mean 3.1 in head length vs. mean 3.7). Counts of anal-fin rays are helpful to differentiate the two species: usually III, 8 for A. pacificus sp. nov. and usually III, 9 for A. berda, respectively. Nominal species are discussed with notes on Acanthopagrus. A key to the currently recognized species of Acanthopagrus, including A. pacificus is provided.
