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).

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., Published as part of Batista-Silva, Valéria Flávia, Frota, Augusto, Kashiwaqui, Elaine Antoniassi Luiz, Abelha, Milza Celi Fedatto, Bailly, Dayani, Gubiani, Éder André & Júnio da Graça, Weferson, 2018, Ichthyofauna from three streams of the lower Iguatemi River in the upper Paraná river basin, Brazil, pp. 363-378 in Check List 14 (2) on pages 369-370, DOI: 10.15560/14.2.363, {"references":["Eigenmann CH (1908) Preliminary descriptions of new genera and species of tetragonopterid characins.
