Taxonomic notes: As indicated by Gibbs et al. (2017: 84), there has been much confusion over the names of several species of Lasioglossum, particularly with respect to consideration of Lasioglossum nymphaearum (Robertson, 1895) as a valid species. Halictus nymphaearus was proposed as a replacement for the preoccupied Halictus palustris Robertson, 1890 by Robertson (1895: 117) and subsequently has most often been considered a valid species. Gibbs (2010: 223) resurrected the name Lasioglossum oceanicum (Cockerell, 1916) from synonymy as the valid name for this species, which has most often (and incorrectly) been referred to as L. nymphaearum (e.g., Mitchell 1960) after discovering (Gibbs 2010: 61) that the lectotype of H. palustris Robertson, labeled as such and deposited at ANSP, pertained to this species (i.e., Lasioglossum albipenne (Robertson, 1890)) rather than to Dialictus nymphaearum sensu auct. Gibbs (2011: 149) later reversed this decision as he was unable to find a valid (i.e., published) lectotype designation (i.e., most of Robertson’s species were treated in Webb 1980, but this specimen was not mentioned); in fact, the designation was published by Cresson (1928: 63), thus Gibbs (2010) was correct and Gibbs et al. (2017: 84) indicated that Lasioglossum oceanicum is the correct name for what has been typically called L. nymphaearum, and the names Halictus palustris Robertson and H. nymphaearus were returned to synonymy under L. albipenne.

Gibbs (2010: 57, 2011: 43) indicated August 2 (2.viii) as a collection date for the lectotype of Halictus nubilis Lovell, 1905, while Covell (1972: 13) indicated August 21 (Aug. 21) for the specimen he designated; the other two specimens he examined were dated Aug. 19 and Aug. 25. Unfortunately, the dates for specimens in the syntype series were not provided by Lovell in original work (Lovell 1905).

DNA Barcode Index Number (BIN): BOLD:AAB6738

The lectotype designations of Gibbs (2011: 43) for H. albipennis Robertson and H. nubilis were not required, as Cresson (1928: 57) and Covell (1972: 13), respectively, had already selected and designated the same specimens, though the latter misspelled Waldoboro as “Waldeboro”.             

Distribution in Canada: Criddle et al. 1924 [ON, QC]; Gibbs 2010, 2011 [BC, AB, SK, MB, ON, NB, PE, NS]; Sheffield et al. 2014 [AB, SK, MB]; Elwell et al. 2016 [BC].

Gibbs (2010, 2011) indicated that this species was common.
