Peristedion picturatum McCulloch, 1926 (family Peristediidae) was distinguished from P. liorhynchus (Gunther, 1872) by a single character, the presence of two bony plates between the anus and first anal ray (vs. three in P. liorhynchus). Our examination of the holotype of P. liorhynchus revealed that it also actually has just two bony plates there, not three. Based on a comparison of the holotype and other material of P. picturatum with the holotype of P. liorhynchus, we conclude that P. picturatum is a junior synonym of P. liorhynchus.
