Fig. 34

Body deep; greatest body depth contained 2.4 to 2.8, head depth 3.2 to 3.6 and caudal peduncle depth 6.1 to 7.2 times in SL; head length 2.8 to 3.3 and caudal peduncle length 6.5 to 7.5 in SL; snout length 2.3 to 2.9, horizontal orbital diameter 2.0 to 4.6 and least interorbital width 2.4 to 3.8 to in HL. Mouth terminal; premaxilla and dentary with one or two teeth rows. Upper lateral line with 20 or 21, lower lateral line with 11-14 pored scales and longitudinal series with 28-33 scales. Transversal series above upper lateral line with 3½-5 scale rows and below lower lateral line with 5-7 scale row. Dorsal fin with XV-XVI,11-13 rays, pectoral fin with 11-13, pelvic fin with I,5 and anal fin with III,8-10 rays ( Graça, Pavanelli, 2007). Ground color greyish to pale brown; black rounded blotch on posterior margin of opercle; dark-brown transverse bars on flank. Dorsal, anal and pelvic fins hyaline and scattered with dark-brown spots.

Maximum standard length. 170.0 mm.

Distribution. Africa, widely introduced everywhere ( Eschmeyer et al., 2017), including Brazil.

Remarks. Coptodon rendalli was identified as Tilapia rendalli (Boulenger, 1897) by Graça, Pavanelli (2007). Dunz, Schliewen (2013), in a molecular phylogeny of the specimens commonly known as “ Tilapia ”, proposed the new combination. Coptodon rendalli is an African species, widely introduced in South America by fish farming.
