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.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.

The genus includes three species from the Neotropical region. The group was reviewed by Erwin and Moore (2007) and two of the species were treated by Straneo (1985). Individuals are generally found in rotten logs.
Separable from all other Morionini by the combination of robust body-form, pronotum with lateral margins rounded to near the base but with a short, distinct sinuation just in front of the hind angle, anterior margin of the labrum nearly straight and simple, median tooth of the mentum acutely formed.
