Family common name: pergid sawflies
Genus: Acordulecera Say, 1836
Acordulecera is a speciose genus of small sawflies. They are stout and generally 4 mm or less in length. As larvae, they feed on broadleaf deciduous trees. This genus is not well-studied, and several species remain undescribed (Smith 2006a, Smith 2010).
There are 55 described species worldwide restricted to the Western Hemisphere, with the greatest species richness in tropical South America. Nine species occur in North America (Smith 2006a, Smith 2010, Taeger et al. 2010).
A preliminary key to species of North American Acordulecera is included in Smith 2010.
The Pergidae can be distinguished from other families by the fused tergum, the lack of fore wing vein 2r, and the lack of hind wing cell A. The family can be distinguished from Argidae by of the number of antennal segments. Acordulecera is easy to recognize with its small size and 6-segmented antennae (Goulet 1992).
North America: In the northern part of its range, Acordulecera occurs as far north as southeastern Canada through the eastern United States and west to Arizona and California. The genus is also found throughout Mexico and Central America, and Dominica, Montserrat, and St. Vincent in the Caribbean (Smith 2006a, Smith 2010).
