Sphecodes davisii Robertson, 1897


Scientific Name: Sphecodes davisii Robertson, 1897

Common Name: Davis\\\\\\\\\\\\\\\' Cuckoo Sweat Bee


Sphecodes davisii Robertson, 1897: 319 [♂].

     Holotype ♂. USA, Michigan [INHS].

Sphecodes persimilis Lovell and Cockerell, 1907: 103 [♀]. Synonymy by Gibbs et al. (2017: 94).

     Lectotype ♀, designated by Covell (1972: 17). USA, Maine, Waldoboro, 14 July [no year provided], on umbelliferous flowers [USNM no. 71595].


Taxonomic Notes: Graenicher (1910: 159) described the ♀ of S. davisii Robertson, but Mitchell (1960: 486, 497), was the first to suggest the possible synonymy of S. persimilis under S. davisii, though did not confirm it. Gibbs et al. (2017: 94) provide a summary of studies in which the synonymy was implied and are considerd here to have made the synonymy official.

Covell (1972: 16) incorrectly spells Waldoboro [Maine] as Waldeboro for the type location of S. persimilis Lovell and Cockerell.

Distribution in Canada: Criddle et al. 1924 [MB, ON, QC, as S. persimilis Lovell and Cockerell]; Mitchell 1960 [ON]; Sugar et al. 1999 [ON, as S. persimilis Lovell and Cockerell]; Sheffield et al. 2013 [NS]; Taylor 2014 [ON]. Discover Life [NB, PE]
