Containing group: Aspredinidae


This genus is rare in museum collections but is widespread in the Orinoco, Amazon and Paraguay-Parana River systems. Based on my trawl collecting experiences they typically occur in waters >5 m in depth.



A genus of small to medium sized banjo-catfishes (up to 90 mm SL) distinguished from all other aspredinids by the following characters: head and body extremely depressed; head ornamentation highly reduced or absent; often a distinct notch in upper jaw; laminar process of pterotic needle-like and directed at a shape right angle; 10-20 anal fin rays; and females carry embryos directly attached to the ventral surface of their bodies as shown below.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
