Dufourea harveyi (Cresson 1878)

County records: Kalamazoo.

Notes. Dufourea harveyi , a specialist on Potentilla , was recently resurrected from synonymy with D. fimbriata fimbriata (Cresson) by Gibbs et al. (2014). Three specimens deposited at MSUC collected between 1960 and 2009 were recently documented from Barry, Jackson and Kalamazoo Counties in a review of Michigan Dufourea ( Gibbs et al. 2014) . The species had not previously been recorded from the eastern United States, although a specimen from northern Ontario had been reported ( Dumesh & Sheffield 2012; as D. fimbriata ). Dufourea fimbriata is fully confirmed only from its type locality of Colorado and from California where subspecies sierrae (Michener) occurs. The four species of Dufourea known from Michigan were reviewed by Gibbs et al. (2014).
