Taxonomy
Amatitlania coatepeque was first formally described in 2007 by the Mexican ichthyologist Juan Jacobo Schmitter-Soto with its type locality given as off the north shore of the island in Lake Coatepeque, El Salvador.[1] In 2014 it was suggested that this taxon was a junior synonym of the type species of the genus Amatitlania, A. nigrofasciata.[2] However, the consensus still treats this as a valid species.[3] The genus Amatitlania is classified in the tribe Heroini[4] within the subfamily Cichlinae, the American cichlids, in the family Cichildaeof the family Cichlidae,[5] within the order Cichliformes.[6]

Etymology
Amatitlania coatepeque is classified within the genus Amatitlania, this name means "of Amatitlan", i.e. Lake Amatitlán, a caldera lake in Guatemala which is the type locality of A. nigrofasciatia. The specific name, coatepeque, is the name of the only known location for this species, the caldera lake of Lake Coatepeque in EL Salvador. The name of this lake is thought to be Nahuatl, combining, coátl, meaning "snake", and tepétl, which means "mountain", giving a toponym that translates as "mountain of the snake".[7]
