A very similar species to the more common Lasioglossum lativentre (Schenck) and some records are probably due to misidentification of that species. Perkins (1922) unfortunately transposed the male genitalia characters, the most reliable way of distinguishing the two species, in his seminal paper on Lasioglossum.
Found from Dorset eastwards to Kent, and north to Yorkshire and Lancashire, and found in south Wales. It is also reported from the Channel Islands.
This is a Palaearctic species, found from Britain to Kazakhstan, north to Sweden and in the south (based on males) in Italy and Greece to north-east Turkey. Reports from the south, outside these areas, are based on females which may not be correctly determined (A W Ebmer, pers. comm.).
