Notes. The female lectotype of Halictus quadrimaculatus (see Cresson 1928) in the ANSP belongs to the species most often referred to as L. divergens in the literature (often in combination with either Halictus or Evylaeus) (Gibbs et al. 2013) although the name macoupinensis (a replacement name for H. quadrimaculatus) has been most often used to refer to L. birkmanni (see above).
