Etymology: Paretroplus: Name from the Greek 'para' meaning 'on the side of'; in taxonomy it is commonly used in generic names to express similarity or relatedness; in the present case it would mean 'next to Etroplus' (S.Kullander, pers.comm. 3/11).

Diagnosis: A member of the deep-bodied clade of Paretroplus and distinguished from all congeners by the presence of a large and essentially square to rounded solid black pectoral patch, located above and slightly posterior to the pectoral-fin base, and generally not extending dorsal to the upper branch of the lateral line (Ref. 78623).
