Introduction

This genus is distributed in the Lago Maracaibo, Orinoco, Amazon basins.

Characteristics

Diagnosis

A genus of small, armored banjo-catfishes (up to mm 32 mm SL) distinguished from all other aspredinids by the following characters: each premaxilla with two bony knobs superficially covered by fleshy papillae; dorsal and ventral armor plates do not overlap; and 2-3 sets of paired pre-anal-fin plates. Other characters not unique to this taxon but useful for identification include: maxillary barbel adnate with head and pectoral spine less than 25% of standard length.

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.
