Soldier flies in the genus Hedriodiscus are large, showy, and restricted to the New World. Hedriodiscus varipes is native to Western N. America. The ranges of 6 species include both the Nearctic and Neotropical regions, and the rest are from the Caribbean, Central and South America.


Hedriodiscus is distinguished from other Nearctic Stratiomyini by the spined scutellum, the antenna with six flagellomeres with the last two flagellomeres forming a stylus, crossvein r-m absent and M1 and M3 distinct (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.
