aequifasciata, Symphysodon discus var. Pellegrin [J.] 1904:250 [Mémoires de la Société Zoologique de France v. 16 (nos 2-4); ref. 3419] Santarém, Amazonas, Brazil. Lectotype: MNHN 1902-0130. Paralectotypes: MNHN 1902-0134 (1) Tefé, 0135 (1) Tefé. Type catalog: Blanc 1962:222 [ref. 20868]. Symphysodon is masculine, aequifasciata is apparently an adjective; it should be aequifasciatus. Lectotype designation by Géry & Bleher 2005:135 [ref. 29228] invalid as the specimen is not clearly identified (either MNHN 1902-0134 or 1902-0135); perhaps confused in Bleher et al. 2007:172 [ref. 29227]. See errata in v. 13 (no. 1):42. Ready et. al. 2006:207 [ref. 29520] selected MNHN 1902-0130 as lectotype.
