( Michigan Agricultural College), 17 Apr. 1886 ( INHS 179717) = Sphecodes persimilis Lovell & Cockerell 1907 County records: Alger , Antrim , Calhoun, Ingham, Kent , Leelanau, Livingston, Oakland, Ottawa, Tuscola, Van Buren. Notes. This is a common and widespread species, originally described from a single male specimen. It is considered a senior synonym of S . persimilis , which was described from the female. Mitchell (1960) pointed out the possible synonymy and Abrams & Eickwort (1980) considered this probable. Mike Arduser and JSA have each applied this synonymy, but its establishment was relatively obscure since it was not done as part of a published revision but rather has appeared online and implicitly in faunal checklists ( Arduser 2010 ; Ascher et al. 2014 ; Goldstein & Ascher 2016 ). Sphecodes davisii is a cleptoparasite of Agapostemon virescens (Fabricius) and A . sericeus (Förster) ( Abrams & Eickwort 1980 ).
