Claremontia

Taxonomy

Family: Tenthredinidae
Family common name: common sawflies
Subfamily: Blennocampinae
Tribe: Blennocampini
Genus: Claremontia Rohwer, 1909
Subgenera: none

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 subfamily Blennocampinae have a diverse set of life histories and habits. Many species are restricted to subtropical and tropical regions, but the genus is still fairly species-rich in North America. Blennocampinae includes many sawflies that feed on ornamental and forestry crops. This subfamily can be recognized by wing venation and bidentate mandibles (Smith 1969d).

Claremontia are small to medium-sized, about 6–7 mm in length, and entirely black, sometimes with light-colored striping present on the legs. The wings are transparent or slightly darkened (Smith 1969d).

Diversity

There are 17 described extant species worldwide. Seven species occur in North America (Taeger et al. 2018).

The monograph for Blennocampinae (Smith 1969d) synonymizes Monophadnoides and Claremontia. The two genera have since been separated, and the only Nearctic species to remain in Monophadnoides is M. rubi (Taeger et al. 2010, Smith pers. comm. 2020).

Genus characters

May be confused with

Claremontia can be confused with similar species in the subfamily Blennocampinae. It can be distinguished from Periclista by the fore wing veins 2A and 3A and by a lack of membranous area on the anepimeron, from Monophadnus by the lack of a divide on the katepimeron, and from Monophadnoides by the relative length of the third and fourth antennal segments and the presence of a tarsal claw basal lobe (Smith 1969d). Claremontia is also characterized by a postocular furrow which is not present in Monophadnoides (Smith 2015).

Distribution

World: This genus is found in North America, central and eastern Europe, and east through Siberia into Mongolia. One species, C. sinobirmana, occurs in Myanmar (Koch 1988a).

North America: Species of Claremontia occur throughout the northern United States with some extensions farther south in California, and through southern Canada extending north to Alaska (Smith 1969d, Koch 1988a).
