Lasioglossum admirandum (Sandhouse, 1924)


Scientific Name: Lasioglossum admirandum (Sandhouse, 1924)

Common Name: Admirable Sweat Bee


Halictus (Chloralictus) admirandus Sandhouse, 1924: 14 [♀].

     Holotype ♀. USA, Massachusetts, Woods Hole, by E. Cattell [USNM no. 26405].

*Dialictus perspicuus Knerer and Atwood, 1966: 883 [♀, ♂]. Synonymy by Gibbs (2010: 52).

     Holotype ♀. CANADA, Ontario, Elgin Co., Iona, 15 September 1963, by G. Knerer, on Solidago [ROM: 83647].


Taxonomic notes: This species is part of the Lasioglossum viridatum (Lovell, 1905) species complex (Gibbs 2010) which includes many non-descript and closely related species (see comment on BINs below) which can be common and widespread throughout Canada and large parts of the United States; this has caused much difficulty with identifications.

DNA Barcode Index Number (BIN): BOLD:ABZ0652

This BIN is shared with Lasioglossum ephialtum Gibbs, 2010, Lasioglossum fattigi Mitchell, 1960, Lasioglossum marinense (Michener, 1936), Lasioglossum pacatum (Sandhouse, 1924), Lasioglossum planatum (Lovell, 1905), Lasioglossum sagax (Sandhouse, 1924), Lasioglossum subviridatum (Cockerell, 1938), and Lasioglossum taylorae Gibbs, 2010.

Distribution in Canada: Knerer and Atwood 1962 [ON], 1966 [ON, as D. perspicuous Knerer and Atwood]; Sugar et al. 1999 [ON]; Sheffield et al. 2003 [NS], 2014 [MB]; Gibbs 2010 [SK, ON], 2011 [SK, ON]; Wrigley et al. 2021 [MB]; Gibbs et al. 2023 [MB].

Based on the distributional data of Gibbs (2010, 2011), it is likely that previous reports of this species from Nova Scotia (i.e., Sheffield et al. 2003) were based on misidentifications.
