In the present study we evaluate the putative cases of sympatric speciation in the genus Herichthys by studying the variation of the head shape using principal component analysis, phylomorphospace and reconstructions of the ancestral states of feeding preferences. Herichthys includes both allopatric as well as sympatric sister-species, as well as sympatric unrelated species and offers thus great potential for evolutionary studies of putatively sympatric speciation. Herichthys is the northernmost group of cichlids in America and one of th
