Theraps

Genus of fish

Genus of fish

Theraps is a genus of cichlid fish that includes only a single species, the Arroya cichlid (Theraps irregularis) from fast-flowing rivers and streams in the Usumacinta and Polochic basins of southern Mexico and Guatemala. It is a medium-sized cichlid, up to 19 cm in standard length.

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, 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. and FishBase agrees.
