Background

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 Tenthredininae subfamily are relatively large compared to others in the family, often with distinct colorful markings. Some are wasp-like with black and yellow stripes (Goulet 1992). Many species’ life histories are not known. Some Tenthredininae species feed uniquely, as adults, on flower pollen and other insects (Smith 1993). They can be distinguished from other subfamilies by wing venation (Goulet 1992).

Leucopelmonus is monotypic. Leucopelmonus annulicornis can be recognized by a wide white band on the elongate antenna and reddish-brown legs and thorax (Taeger et al. 2010, BugGuide 2019).

Diversity

There is one described extant species worldwide, and it is Nearctic (Taeger et al. 2010).

May be confused with

Leucopelmonus can be confused with similar species in the subfamily Tenthredininae. It can be distinguished from most other genera by the lack of on angle on the posteroventral area of metepimeron, length of the postnotum, and distance between cenchri (Goulet 1992).
