The 12 species of Caloparyphus are found in the U.S. and Canada, with C. decemmaculatus ranging into Mexico.


Caloparyphus are large, black flies with some abdominal patterning. Caloparyphus is distinguished from other Nearctic Oxycerini by the elongated antenna, pedicel shorter than the combined length of the basal three flagellomeres, the scutellar spines separated by at least their length (if the scutellar spines are closer, the wing with only scattered microtrichia distally), and aedeagus trifurcated distally (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.
