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 . Material examined.
