Synopsis
We assess morphological diversity of species of the Cynoscion group in the Gulf of Guayaquil (GOG) using
traditional morphometric methods. Five species from the GOG assemblage (C. albus, C. analis, C. pho-
xocephalus, C. squamipinnis, and Isopisthus remifer) are compared to four species from a relatively
well-studied assemblage in the western Atlantic (C. arenarius, C. nebulosus, C. nothus, and C. regalis). The
two regional species assemblages broadly overlap in morphology, but sympatric species segregate relatively
