Satanoperca sp.

Fig. 35

Body deep; greatest body depth contained 2.0 to 2.8, head depth 2.5 to 3.3 and caudal peduncle depth 5.8 to 7.7 times in SL; head length 2.5 to 3.3 and caudal peduncle length 6.0 to 9.4 in SL; snout length 1.9 to 2.2, horizontal orbital diameter 2.8 to 3.7 and least interorbital width 3.3 to 3.6 in HL. Mouth terminal; premaxilla and dentary with one or two teeth rows. Upper lateral line with 17-21 and lower lateral line with 8-12 pored scales, and longitudinal series with 27-33 scales. Transversal series above upper lateral line with 3½-4 scale rows, and below lower lateral line with 6-9 scale rows. Dorsal fin with XIV-XVI,9-11, pectoral fin with 13-16, pelvic fin with I,5 and anal fin with III,6-8 rays ( Ota, 2013). Ground color greenish; dark-brown longitudinal band, from opercle to caudal peduncle; seven dark-brown transverse bars on flank. Soft portion of dorsal and anal fins with white spots; pelvic fin with iridescent blue stripe; black rounded blotch on base of upper caudal-fin lobe.

Maximum standard length. 173.0 mm.

Distribution. Rio Tocantins-Araguaia and upper rio Paraná basins.

Remarks. Satanoperca sp. was identified as S. pappaterra by Graça, Pavanelli (2007). Ota (2013), in a revisionary study of Satanoperca Günther, 1862 , restricted the distribution of S. pappaterra to the rio Guaporé and río Paraguay basins, and proposed the new identification for the specimens from the upper rio Paraná floodplain. Satanoperca sp. is currently considered non-native from the upper rio Paraná (e.g. Langeani et al., 2007; Kullander, 2012), and its occurence in the region has been associated with the filling of the Itaipu Reservoir (Júlio Jr. et al., 2009), or with the introduction from other river basins.
