The ♂‚ was described by Mitchell (1960).
The DNA Barcode Index Number (BIN) for this species is BOLD:AAD2971. Though Gibbs (2010, 2011) were not able to confirm this species in Canada, Mitchell (1960) recorded it from Nova Scotia.
♀ body length: 4.03–5.37 mm; head length: 1.06–1.34 mm; head width: 1.18–1.46 mm; forewing length: 3.11–3.72 mm

Little is known about the biology of this species, though it is likely eusocial like most other Lasioglossum, subgenus Dialictus. Gibbs (2011) indicated that this species was rare in Canada.
