Lasioglossum (Dialictus) dreisbachi ( Mitchell 1960)  ( viridatum  group)

Dialictus dreisbachi Mitchell, 1960: 391  . (Michigan holotype)

Holotype. ♀ USA: Michigan: Clare Co.: 24 May 1958 (R. & K. Dreisbach) ( NMNH). 

County records: Allegan, Antrim, Arenac, Charlevoix, Cheboygan, Clare, Clinton, Crawford, Eaton, Gladwin, Ionia, Iosco, Isabella, Kalkaska  , Kent, Lake, Lapeer, Lenawee, Midland, Montcalm, Ottawa, Saginaw, Shiawassee, Van Buren, Washtenaw.

Notes. This species appears to have a northern distribution, reaching its southernmost limits in states that border Canada. Its range remains uncertain due to insufficient sampling in boreal regions of Canada and northern states, and because bee specialists have not been able to distinguish this from other species in the taxonomically challenging Lasioglossum viridatum  species group of Gibbs (2010b). Nevertheless, L. dreisbachi  has unique mesepisternal sculpturing, which abruptly changes from coarsely rugose to smooth ( Gibbs 2010b).
