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).
Eponymy: Professor Georges Jean-Jacques Petit (1892–1973) was a French marine biologist at the Muséum National d’Histoire Naturelle. [...] (Ref. 128868), visit book page.

Spine dorsali (totale) : 17; Raggi dorsali molli (totale) : 14; Spine anali: 9; Raggi anali molli: 14. Diagnosis: Paretroplus petiti is a deep-bodies Paretroplus and it is distinguished from all congeners, except P. menarambo, by dark brown colouration in combination with the lack of a strong lateral barring pattern (Ref. 78623). It is distinguished from P. menarambo by the absence of a pinstriped pigmentation pattern, which results in the latter species due to conspicuous spotting on scales (Ref. 78623). Further, P. petiti can be distinguished from all congeners by a deep, disk-shaped body and the presence of lateral ridges of scales that are free from the fin membranes over the entire length of the soft dorsal and anal fins (Ref. 78623).
Body shape (shape guide): fusiform / normal.
