What is "cichlasomatinae"

The Cichlasomatinae are a subfamily of cichlid fishes, including all ciclids native to islands in the Caribbean ( Cuba and Hispaniola), USA (southern Texas), Mexico and Central America, and many of the cichlids from South America (the other South American subfamilies are Astronotinae, Cichlinae, Geophaginae, and Retroculinae). The subfamily Cichlasomatinae is often divided into two tribes: Cichlasomatini and Heroini.
