There are 25 species of Psellidotus native to the Neotropical region, 18 to the Nearctic, and 3 are shared between the two regions. The species were previously erroneously placed in the genus Labostigmina until it was synonymized with Psellidotus (Woodley 2001).


Psellidotus is distinguished from other Nearctic Stratiomyini by the spined scutellum with the spines approximated, the antenna with five flagellomeres without forming a stylus, the antenna flagellum cylindrical, the face produced or tuberculate, and the head not wider than the thorax (James 1981).

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.
