Abstract

Pariosternarchus amazonensis, new genus and species, is described from the Amazon river of Brazil and Peru. It is unique among apteronotids in possessing a wide head that is flattened on its entire ventral surface, and in possessing highly expanded mandibular laterosensory canals. The phylogenetic position of Pariosternarchus is hypothesized by inclusion in a previously published data matrix of osteological and other morphological characters. Among apteronotids Pariosternarchus is inferred to be the sister taxon to Sternarchella, with which it shares several derived features associated with a life history as benthic foragers in large whitewater Amazonian rivers: a short gape, a large maxilla with a robust anterior process, gill rakers attached to gill arches, and flexible gill rakers that are not ossified to their tips.
