Euparyphus contains 4 subgenera. Euparyphus is most diverse in the Nearctic region, with 2 species shared between Nearctic and Neotropical regions, and 2 species found only south of the USA. Aochletus has 4 species from the Nearctic region, 4 from the Neotropical region, and 1 species shared between the two regions. Nigriparyphus has 1 species in the Neotropics, the rest in Nearctic. Euparyphus (Parochletus) nebulosus is found in SW USA and N. Mexico and E. (P.) pardalinus is from California and Utah (Woodley 2001).


Euparyphus is distinguished from other Nearctic Oxycerini by the elongated antenna, pedicel shorter than the combined length of the basal three flagellomeres, spines of scutellum always closer together than their length, the wing with thick, uniform microtrichia distally(James 1981).

R4 is fused with Rand cell r3 is five or less times as long as wide in the subgenera Aochletus and Parochletus. R4 is separate from Rand cell r3 is six or more times as long as wide in the subgenera Nigriparyphus and Euparyphus. Vein CuA2 and the veins around cell dm are faint in Aochletus but distinct and strong in Parochletus. The second to last antennal flagellomere is much shorter than the third to last antennal flagellomere in Nigriparyphus but they are about equal in length in Euparyphus (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.
