Anthidiellum (Loyolanthidium) notatum boreale (Robertson 1902) (New state record)

County records: Cass, Ingham.

Notes. The holotype male is from Carlinville, Illinois (INHS). Mitchell (1962) lists Illinois in the distribution of both subspecies known from Michigan. The collection of males together at the same site suggests the subspecies are syntopic. Additional taxonomic study is needed to determine if A. n. boreale warrants subspecific or specific status. Urban (2001) described and reviewed the subgenus (as a genus), but did not examine any specimens of A. n. boreale , nor did she indicate its current taxonomic status, whereas she elevated the western A. gilense (Cockerell 1897) and A. robertsoni (Cockerell 1904) to specific rank.
