A new Nearctic Scolioneura (Hymenoptera, Tenthredinidae) mining leaves of Vaccinium (Ericaceae)

Scolioneura vaccinii Smith & Eiseman, sp. n., is described. It was reared from blotch mines in Vaccinium parvifolium Sm. (Ericaceae) collected in Washington State, USA. This is the first known native species of Scolioneura in the Nearctic Region and the first known sawfly leaf miner of Vaccinium as well as the order Ericales. Characters are given to separate it from other species of Scolioneura, and the life history is presented. One parasitoid, Shawiana sp. (Braconidae) was reared from the leaf mines.
