Containing group: Aspredinidae


This genus has several times in its history been sunk in synonymy with Aspredo including most recently by Mees (1987). Friel (1994) found this genus to be the sister group to a clade containing Aspredo and Aspredinichthys and removed it from Aspredo to make that genus monophyletic.



A genus of large banjo-catfish (up to 320 mm SL) distinguished from all other aspredinids by the following character: 4+5 caudal-fin rays. They are further distinguished from other members of the Aspredini by the absence of accessory maxillary barbels and the presence of well developed unculiferous tubercles rows.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into 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.
