Taxonomic notes: This species has typically been referred to as L. nymphaearum, which was proposed as a replacement for Halictus palustris Robertson, 1890 which is a primary homonymy of H. palustris Morawitz, 1876. The lectotype specimen for H. palustris selected by Cresson (1928: 63) belongs to the species L. albipenne (Robertson, 1890). The name L. oceanicum, previously considered a junior synonym of L. nymphaearum, was resurrected by Gibbs (2010: 223).

Distribution in Canada: Sugar et al. 1998 [ON, as L. nymphaearum (Robertson, 1895)]; Sheffield et al. 2003 [NS, as L. nymphaearum (Robertson, 1895)]; Nol et al. 2006 [ON]; Gibbs 2010 [ON], 2011 [ON, as L. nymphaearum (Robertson, 1895)].
