description: <b> <i>Hoplias mbigua</i> Azpelicueta, Benítez, Aichino, Mendez, 2015</b> <b>Fig. 13</b> Body elongated; greatest depth contained 4.5 to 5.2, caudal peduncle depth 7.2 to 8.3 times in SL; head length 2.9 to 3.6, predorsal distance 2.0 to 2.3 and caudal peduncle length 6.8 to 9.4 in SL; snout length 3.5 to 4.0, horizontal orbital diameter 5.8 to 7.5 and least interorbital width 3.6 to 4.3 in HL. Mouth terminal; premaxilla with 8, dentary with 2 rows of teeth, outer row with 13-15 and inner row with 13-16; maxilla with 30-40 teeth. Lateral line with 41- 43 pored scales; series between lateral lines with 13 scale rows. Dorsal fin with 14 or 15, pectoral fin with 11-14, pelvic fin with 8 or 9, anal fin with 9-11 and caudal fin with 19 rays (Azpelicueta <i>et al</i>., 2015; Bifi, 2013). Ground color pale brown; dark-brown longitudinal band, from opercle to caudal peduncle. Some specimens with darkbrown stripes radiating ventrally and posteriorly from orbit through infraorbitals; ventral surface of dentary with lightbeige stripes alternating with dark-brown stripes. Fins with dark-brown spots, sometimes forming dark-brown stripes parallel with fin base. <b>Maximum standard length.</b> 293.0 mm. <b>Biological data.</b> See <i>Hoplias</i> sp. 1 of Graça, Pavanelli (2007). <b>Distribution.</b> Paraná-Paraguay system. <b>Remarks.</b> <i>Hoplias mbigua</i> was identified as <i>Hoplias</i> sp. 1 by Graça, Pavanelli (2007). Azpelicueta <i>et al.</i> (2015) described the new species only from the lower río Paraná basin, in Argentina; however, the occurrence of <i>H. mbigua</i> in the upper rio Paraná floodplain has been reported since the submersion of the Sete Quedas Falls by the Itaipu Reservoir (<i>e.g.</i> Bertollo <i>et al.</i>, 2000; Pazza, Júlio Júnior, 2003; Graça, Pavanelli, 2007; Júlio Júnior <i>et al</i>., 2009; Bifi, 2013). Additionally, Bifi (2013), in a revisionary study of the <i>Hoplias malabaricus</i> (Bloch, 1794) species group from the río de la Plata basin, provided further useful diagnostic features for this species (identified as <i>Hoplias</i> sp. A). <i>Hoplias mbigua</i> is a non-native species from the upper rio Paraná, and its occurrence can be associated with the filling of the Itaipu Reservoir and the consequent inundation of the Sete Quedas Falls (Júlio Júnior <i>et al</i>., 2009).
