With a body length of 4–6 mm this is the smallest of the Nomada species found in the British Isles. The female is unusual in that the gastral tergites are devoid of yellow lateral markings of any kind. In Britain the species is unique in being entirely a cleptoparasite of small Lasioglossum species.
The bee occurs throughout much of southern England from East Kent to West Cornwall, north to Salop, though apparently largely absent from eastern England north of Middlesex. It is scarce in Wales with records from Gwent (Perkins, 1918) and South Glamorgan. There are no records from northern Britain or Ireland. In the Channel Islands it is known from Guernsey (Luff, 1895; Saunders, 1902, 1903) and Jersey (Saunders, 1903).
Widely distributed in central and southern Europe, from France to Turkey; the Middle East (Israel) and North Africa (Algeria and Morocco). Also reported from Japan (Hirashima, 1982).
