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); lamenabe: Lamena is a Malagasy word that translates as 'red one', and be is a Malagasy word meaning 'big', in reference to both the live colouration of this species and its large size relative to members of its sister clade, P. tsimoly and P. nourissati (Ref. 78623).

Taggstrålar i ryggfenan (totalt) : 15 - 17; Mjukstrålar i ryggfenan (totalt) : 11 - 16; Taggstrålar i analfenan: 7 - 9; Mjukstrålar i analfenan: 10 - 12; Ryggkotor: 30 - 32. Diagnosis: A shallow-bodied, elongate Paretroplus diagnosed from all congeners except P. nourissati and P. tsimoly by the presence of two wide and convergent, below the lateral midline, dark brown to black midlateral bands, representing the second and third or third and fourth bars in series (Ref. 78623). Paretroplus lamenabe is distinguished from P. nourissati and P. tsimoly by a deeper body, 47.0-54.3% of standard length vs. 38.1-43.5% and 41.1-46.8% respectively; by the presence of pelvic fins that extend beyond origin of the anal fin when adducted, and by a larger adult size , regularly exceeding 180 mm standard length vs. less than 160 mm standard length in P. nourissati and P. tsimoly (Ref. 78623).
Body shape (shape guide): fusiform / normal.
Found in a generally turbid river with muddy banks, from a rocky stretch with an accelerated current (Ref. 78623).
