Gobulus birdsongi is described as a new species from the Pacific coast of Panama. The two other known species of Gobulus from the eastern Pacific, Gobulus crescentalis and G. hancocki are redescribed. Gobulus birdsongi differs from other species in the genus in having more numerous second dorsal and anal rays. Gobulus hancocki differs from G. crescentalis in having a much smaller eye. The genus is distinctive in having reversed countershading, with the ventral surface of the body darker than the dorsal surface.
