Moenkhausia australe ( Eigenmann, 1908)

Moenkhausia australe Eigenmann 1908: 103 [original description]. Moenkhausia sanctaefilomenae — Reis et al. 2003: 150.

Material examined. Table 2; Figure 5H.

Deep body; terminal mouth; inner row of premaxilla with 5 teeth, outer with 3 or 4, dentary with 9–12 and maxilla with 1 or 2 teeth. Lateral line complete, with 19–26 pored scales; longitudinal series with 24–26 scales; transversal series above lateral line with 4, 4½ or 5 scale rows and below with 3, 3½ or 4 scale rows. Dorsal fin with 11, pectoral fin with 11–13, pelvic fin with 8, anal fin with 24–27 and caudal fin with 19, total rays. Ground color silvery; scales with dark-brown border, conferring reticulated pattern to body; 1 dark-brown humeral spot; anterior half of caudal peduncle with light area. Hyaline fins, except caudal fin. Moenkhausia australe is morphologically similar to M. forestii and M. sanctaefilomenae , but can be distinguished from them by having lateral line completely pored, rarely disrupted (vs lateral line incompletely pored, in M. forestii and M. sanctaefilomenae ).

Material examined. Table 2; Figure 5I.

Elongated body; terminal mouth; inner row of premaxilla with 5 teeth, outer with 2–5, dentary with 4 and maxilla with 2 or 3 teeth. Lateral line complete, with 29–34 pored scales; transversal series above lateral line with 5 scale rows and below with 3 scale rows. Dorsal fin with 11, pectoral fin with 12–13, pelvic fin with 8, anal fin with 24–26 and caudal fin with 19, total rays ( Benine et al. 2004). Ground color silvery to pale yellow; dark-brown longitudinal stripe from opercle (conspicuously from vertical through dorsal-fin origin) to median caudal-fin rays; distal portion of caudal-fin lobes equally dark brown.
