Lasioglossum admirandum (Sandhouse, 1924)
Properties
Scientific Name: Lasioglossum admirandum (Sandhouse, 1924)
Common Name: Admirable Sweat Bee
Taxonomy
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 viridatum species-group (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 L. ephialtum, L. fattigi, L. marinense, L. pacatum, L. planatum, L. sagax, L. subviridatum, and L. taylorae.
Biology: This species is likely eusocial like most other Lasioglossum, subgenus Dialictus. Gibbs (2010) indicated that this species was common in Canada, though uncommon in eastern North American (Gibbs 2011); the few records known from Canada suggest uncommon, though it is possible that many specimens await identification.
Distribution in Canada: Knerer and Atwood 1962 [ON], 1966 [ON, as D. perspicuous Knerer and Atwood]; Sugar et al. 1996 [ON]; Sheffield et al. 2003 [NS], 2014 [MB]; Gibbs 2010 [SK, ON], 2011 [SK, ON]; Wrigley et al. 2022 [MB]; Gibbs et al. 2023 [MB].
Based on current (i.e., Gibbs 2010, 2011), it is likely that reports of this species from NS (see Sheffield et al. 2003) are in error.
Extent of Occurrence (EOO) in Canada (http://geocat.kew.org/): 322,922 km2
Index of Area of Occupancy (IAO) in Canada (http://geocat.kew.org/): 96 km2
Body length: ♀ 5.00-6.50 mm
Forewing length: ♀ 3.97-4.45 mm
