Athalia cornubiaeBenson (Hymenoptera: Tenthredinidae: Allantinae), A Sawfly Genus and Species New to North America

Abstract

Athalia cornubiae Benson, an Old World species that feeds on Sedum (Crassulaceae), is reported from North America. It was collected in a Lindgren funnel trap in East Syracuse, Onondaga Co., New York, U.S.A. in 2007 and found in Malaise trap collections at a residence in Ottawa, Ontario, Canada, in 2010. This is the first record of both the genus and species in the Western Hemisphere.
