Family common name: common sawflies
Genus: Prionourgus Goulet, 1986
The Tenthredinidae are the most species-rich family and are found throughout the world, in all continents but Antarctica. They are known as the “common sawflies.” They can generally be recognized by a cylindrical body and long, segmented antennae. Otherwise, they come in a variety of colors, sizes, and forms (Goulet 1992).
Sawflies in the Selandriinae subfamily are relatively small and slender. The range of Selandriinae is worldwide; it occurs on all continents except Antarctica (Goulet 1992). It is the most common and diverse group of tenthredinids in tropical regions, particularly in Central America, South America, and Southeast Asia (Smith 1969e). Selandriinae contains the only known sawflies that feed on non-vascular plants, specifically ferns (Smith et al. 2013). The subfamily can be distinguished from other subfamilies by wing venation (Goulet 1992).
Prionourgus can be confused with similar species in the subfamily Selandriinae. It can be distinguished from most other genera by the distinct punctures on the head and mesoscutum, and from the other Dolerini genus in the tribe, Dolerus, by the malar space length and the clypeus margin (Goulet 1992).
World: The genus is North American (Taeger et al. 2010)
North America: Prionourgus salmani is known from San Bernardino County in southern California (Goulet 1986).
