Further information: Astatheros Pellegrin, 1904 (type species: Heros heterodontus), Erythrichthus Meek, 1907 (type species: Heros citrinellus) and Curraichthys Fernandez-Yepez, 1969 (type species: Heros lobochilus) are considered as synonyms to Amphilophus by Kullander (2003). Evidence from molecular phylogenies, however, suggest that Amphilophus is polyphyletic and Aststheros a natural group (Martin & Bermingham, 1998; Hulsey et al. 2004), so that some authors consider Astatheros as valid (Stauffer & McKaye, 2002; Kranefeld & Schindler, 2005; Concheiro et al. 2007). Based on data published in the recent years, I follow these authors and consider Astatheros as a distinct taxon.
In the lakes of Nicaragua, species of the genus Amphilophus apparently underwent an adaptive radiation leading to various closely related but distinct forms (Stauffer & McKaye, 2002). This includes cases of sympatric speciation in small crater lakes (Refer to Barluenga et al. 2006 for potential sympatric speciation in Lake Xiloa. Also consider the response of Seehausen et al. 2006 in the same journal pointing out that multiple invasion and introgression may account for the patterns docemented by Barluenga et al. 2006). Within Amphilophus, there might be a couple of undescribed species.
The taxonomic assignment of some species is still not entriely clear. Based on the results of Concheiro et al. (2007), A. trimaculatus is tendatively included in Amphilophus here (but see a discussion of the topic here). Furthermore, the placement of A. calobrensis (which according to Concheiro et al. 2007 is to be assigned to a yet undescribed genus) and A. nourissati in Amphilophus is likely not definite.
