Identification: This genus contains a single species. Keys were provided by Schultz (1944) and Taphorn and Lilyestrom (1984). As well as giving diagnostic characteristics in his original description, Schultz (1944) provided a representative illustration of the species. Distinguishing characteristics and color photographs of live fish were given by Burgess (1989). Adults are large and colorful, with a color pattern similar to that of another large pimelodid catfish, Leiarius marmoratus.

† Populations may not be currently present.
Means of Introduction: Probable aquarium release (Howells 2001).
Status: Failed in Texas.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
