Geophagini
Geophagini is a Tribe (biology), tribe of cichlids from the subfamily Cichlinae, the American cichlids. It is the sister taxon to the clade which includes the Cichlasomatini and Heroini. Fishes in the Geophagini are distributed from Panama south to Argentina, it is the most speciose of the seven tribes within the Cichlinae and it is subdivided into three sub-tribes, Acarichthyina, Crenicaratina, and Geophagina which together contain over 200 species. Geophagines show morphological and behavioural specialisations to enable them to sift the substrates within their mouths so that they can separate benthic invertebrates from substrates dominated by sand or silt. Classification The Geophagini are classified as follows: * Subtribe Acarichthyina Sven O. Kullander, Kullander, 1998 ** Genus ''Acarichthys'' Carl H. Eigenmann, C. H. Eigenmann, 1912 ** Genus ''Guianacara'' Kullander & Han Nijssen, Nijssen, 1989 * Subtribe Crenicaratina Kullander, 1998 ** Genus ''Biotoecus'' C. H. Eigenmann & ...

Saxatilia
''Saxatilia'' is a South American cichlid genus in the genus group Geophagini. The genus was only erected in mid-2023 by four South American ichthyologists and their Swedish colleague Sven O. Kullander, and the name is a near-tautonym of the chosen type species. Previously, the species placed in ''Saxatilia'' belonged to the genus ''Crenicichla'' and formed the ''Crenicichla saxatilis'' species complex. Of all the genera of pike cichlids, ''Saxatilia'' has the widest distribution area. It occurs in the Amazon Basin, in the drainage basin of the Orinoco, in the entire river basin of the Río de la Plata, the Río Paraná and the Río Uruguay, in the coastal rivers of the Guyanas, on the islands of Trinidad and Tobago, in the coastal rivers of northeastern Brazil and in the lagoons Lagoa dos Patos and Lagoa Mirim in the south of Brazil. Characteristics Like all pike cichlids, the ''Saxatilia'' species have an elongated body. Males and females of the ''Saxatilia'' species Sexual di ...
