Taxonomy and systematics of the herichthyins (Cichlidae: Tribe Heroini), with the description of eight new Middle American Genera
Abstract
Copyright © 2015 Magnolia Press. In recent years great strides have been made for improving our understanding of the evolutionary relationships among neotropical cichlids, particularly within the clade Heroini and its crown clade the herichthyins. Most phylogenetic studies have largely converged on congruent topologies for relationships among species and major lineages within the herichthyins. One major aspect missing from previous studies of these cichlids is a formal taxonomic revision, including the redefining of genera. Based on analysis of 52 species and three mitochondrial and two nuclear loci, we generate a Bayesian phylogeny for the herichthyin cichlids, and formally revise the taxonomy for genera within this clade using morphological features. Eight new genera are recognized and a key to all 16 genera of herichthyin cichlids is also presented.
