The majority of Middle American cichlids are placed in the informal assemblage 'Cichlasoma.' The group is divided into eight sections which appear to be based primarily on trophic morphology. Although several members of 'Cichlasoma' have been used in ecomorphological, behavioral, and biogeographic studies, no phylogenetic hypotheses for the group exist. In an attempt to develop a better understanding of the...
