Lasioglossum cattellae (Ellis, 1913)

Halictus cattellae Ellis, 1913: 209 [♀,♂‚]

     Holotype ♀. USA, New York, Garrison [UCMC]

Dialictus alternatus Mitchell, 1960: 433 [♂‚] [synonymy by Gibbs 2010: 89]

     Holotype ♂‚. USA, Massachusetts, Forest Hills, 29–30 August 1922, by W.M. Wheeler [MCZ no. 30469]

Species Notes

Grixti and Packer (2006) reported this species from Southern Ontario, but Gibbs (2010) re-examined their specimens and indicated they were incorrectly determined, and were actually L. zephyrum; the earlier records from Ontario by Knerer and Atwood (1962) could not be confirmed (Gibbs 2010).Thus, this species has not yet been recorded for Canada, though Gibbs (2010) indicated that it likley occurs in Ontario and Quebec.

The DNA Barcode Index Number (BIN) for this species is BOLD:AAB6998, which is identical to Lasioglossum tenax, which does occur in Canada.

Size

♀ body length: 4.82–5.86 mm; head length: 1.37–1.49 mm; head width: 1.37–1.51 mm; forewing length: 3.97–4.15 mm

♂‚ body length: 4.33–4.45 mm; head length: 1.32–1.38 mm; head width: 1.30–1.37 mm; forewing length: 3.48–3.54 mm

Biology

Little is known about the biology of this species, though it is likely eusocial like most other Lasioglossum, subgenus Dialictus. Gibbs (2010) indicated that this species did not occur in Canada, though will likely be found in Ontario and Quebec.
