This tree diagram shows the relationships between several groups of organisms.

The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

Containing group: Aspredinidae


This new genus is widespread in the Orinoco, Amazon and Paraguay-Paraná basins. Specimens of Pseudobunocephalus may be mistaken at first glance as juveniles of Bunocephalus and are often in mixed lots with larger Bunocephalus specimens.



A genus of relatively small banjo catfishes (up to 80 mm SL) distinguished from other aspredinids by the following characters: dentary teeth restricted to a broad tooth patch near symphysis of lower jaw; metapterygoid does not contact quadrate; posterior end of palatine forked; fourth pharyngobranchial absent; gill rakers absent on all gill arches; and parapophysis of fifth vertebrae oriented anteriorly. Characters not unique but useful for identification include: jaws equal, mouth terminal; lateral line truncated at approximately the level of the dorsal fin origin; dorsal- and ventral-most principal caudal rays much shorter than others and dorsal- and anal-fin membranes not adnate with body.

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.
