" Central American cichlid taxonomy has been in turnoil since the breaking of the Cichlasoma genus by Sven Kullander in 1983. Since that time, much has been learnt and a base for a more stable taxonomic classification is about to be reached. The last paper by Oldrich Rican and collaborators takes into account an unprecendent number of cichlid species and an equally unprecedent number of genetic and morphological characteristics to produce probably the most updated phylogenetic view of these organisims. Has a stable base for taxonomic classification has been reached? we are getting close to, but we likely are not there yet "
