Theraps is a genus of cichlid fish found in moderately to fast-flowing rivers and streams on the Atlantic slope of southern Mexico and northern Central America. They are medium-sized cichlids.[1][2]

Species and taxonomy[]

Historically, Theraps was included in Cichlasoma. Once recognized as its own genus, it sometimes included a wide range of species now known to belong in other genera, including Cincelichthys, Chortiheros, Chuco, Cryptoheros, Kihnichthys, Oscura, Paraneetroplus, Rheoheros, Talamancaheros, Tomocichla and Wajpamheros. In a major review of 2015, only five species remained in this genus,[1] but in 2016 it was shown that four of these were not close relatives of the Theraps type species, T. irregularis, resulting in them being moved to Chuco and Wajpamheros.[2] As a consequence, Catalog of Fishes now recognizes Theraps as only including the type species T. irregularis,[3] but FishBase include both it and the three Chuco species in Theraps, resulting in a genus that is not monophyletic.[2] The four species placed in this genus by FishBase are:[4]
