Lasioglossum (Dialictus) subversans ( Mitchell 1960)

Dialictus subversans Mitchell, 1960: 419 . (Michigan holotype)

Holotype. ♀ USA: Michigan: Otsego Co.: 26.iv.1944, R.R. Dreisbach ( NMNH).

County records: Dickinson, Ontonagon, Otsego, Van Buren.

Notes. Lasioglossum subversans was poorly documented in the literature until revisionary studies by Gibbs (2010 b, 2011) who treated it as synonymous with Dialictus perpunctatulus Knerer & Atwood. Lasioglossum subversans appears to have a northern distribution, extending across Canada but only reaching south into the USA in northern Michigan and Maine.
