Lasioglossum (Dialictus) michiganense ( Mitchell 1960) ( platyparium group)

Paralictus michiganensis Mitchell, 1960: 448 . (Michigan holotype)

Holotype. ♀ USA: Michigan: Wayne Co.: 2 Jun. 1940, Beebe ( NMNH).

County records: Allegan, Ingham, Kalamazoo, Wayne.

Notes. Lasioglossum michiganense is presumed to be a social parasite of other L. ( Dialictus ) ( Michener 1978, Gibbs et al. 2012), but its host is unknown and range limits remain uncertain. The female examined was collected in a riparian area adjacent to a woodlot. Collection locations are frequently associated with nearby wooded habitat (e. g., Giles & Ascher 2006). However, it has also been reported from an urban park in the city of Chicago ( Tonietto & Ascher 2009).
