Type-species: Callichthys pectoralis Boulenger, 1895.
The species of Lepthoplosternum are traditionally known, especially in the world-wide aquarium trade, as "dwarf hoplos" and are frequently identified as Hoplosternum pectorale. See the Complete Catalogue for authorships, synonyms, type-localities, and references.

Containing group: Callichthyidae

Diagnosis

Lepthoplosternum is diagnosed by the possession of a single unbranched ray in the leading edge of the anal fin; and the lower lip with a small lateral notch in addition to the median notch.

Distribution

Unlike all other genera of subfamily Callichthyinae, the species of Lepthoplosternum are absent in the northern portion of the South American continent, north of the rio Amazonas. The species are found in the upper rio Amazonas in Peru (L. altamazonicum), middle rio Madeira (L. beni), rio Paraguay (L. pectorale), and in the laguna dos Patos drainage (L. tordilho) in southern Brazil.

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.
