Lasioglossum (Dialictus) floridanum (Robertson 1892) ( pilosum group) (New state record)

County records: Lake, Newaygo, Ottawa, Van Buren.

Notes. Until Gibbs (2011), this was considered a subspecies of L. pilosum (Smith) that was restricted to the southeastern USA. Lasioglossum floridanum was found to range further north to overlap extensively with L. pilosum, including the northwest corner of Illinois (Gibbs 2011; Grundel et al. 2011). It was raised from subspecific status by Gibbs (2011) based on the morphological and molecular differences and sympatric distribution with L. pilosum .
