Martins, FO & F Langeani, 2012. Hisonotus piracanjuba, a new species of Hypoptopomatinae (Siluriformes: Loricariidae) from the rio Paranaíba, upper rio Paraná system, central Brazil. Ichthyological Exploration of Freshwaters 23: 29–36.
Abstract
Hisonotus piracanjuba, new species, is described from headwaters of the rio Paranaíba, upper rio Paraná. The sharing of a pair of rostral plates in the anterior part of the snout, the supraopercular plate receiving the laterosensory canal from the compound pterotic before the preopercle, and paired fenestrae in the anterior portion of the basipterygium, suggests a close phylogenetic relationship among H. insperatus, H. luteofrenatus and the new species.
