Apistogramma wolli can be distinguished by the following characters: medium-sized

(males to 62 mm, females to 40 mm SL); laterally compressed; moderately high-backed and elongate; and pronounced sexual dimorphism and dichromatism. It differs from all known congeners by a combination of the following characters: massive jaws and hypertrophied yellow lips in adult males; dorsal fin with serrated membranes, truncated in females; small (but in females large) squarish lateral spot on center of vertical bar 3; large round, in females upright oval, caudal spot; caudal fin lyrate, in females rounded, with red marginal band to upper and lower lobes (Ref. 104987).
