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).
