Lasioglossum (Dialictus) izawsum Gibbs, 2011

Counties: Dakota

Comments: Four females and one male are tentatively identified as L. izawsum, with images of the male and a female examined by J. Gibbs. However, this represents a large range expansion (Gibbs 2011) and there is the possibility that these specimens are a new species (J. Gibbs personal communication).
