Species Notes

The ♂‚ was described by Knerer and Atwood (1966). Lasioglossum interruptum (Panzer) is a subjective senior synonym of Halictus interruptus atlanticus Cockerell. Thus, the name Lasioglossum atlanticum (Mitchell) is unavailable due to secondary homonymy (Ebmer 1976).

The DNA Barcode Index Number (BIN) for this species is BOLD:AAA3782, which is shared with Lasioglossum weemsi.



♀ body length: 4.70–5.67 mm; head length: 1.22–1.54 mm; head width: 1.30–1.63 mm; forewing length: 3.42–4.03 mm

♂‚ body length: 4.03–4.70 mm; head length: 1.27–1.34 mm; head width: 1.30–1.37 mm; forewing length: 3.36–3.48 mm



Little is known about the biology of this species, though it is likely eusocial like most other Lasioglossum, subgenus Dialictus. Gibbs (2010) indicated this species was rare in Canada, though common in the eastern United States. It has sometimes been misidentified as L. admirandum.
