Notes. The application of this name has undergone a recent change ( Gibbs et al. 2013 ). Recent examination of the lectotype of Halictus quadrimaculatus Robertson 1890 (described as 4-maculatus ; Robertson’s name was preoccupied by Hylaeus quadrimaculatus Schenck, 1853 [= Lasioglossum interruptum (Panzer, 1798) of Europe] so was replaced by Halictus macoupinensis Robertson 1895 ), designated by Cresson (1928) , revealed that that name macoupinensis has been used incorrectly by most authors. The type series was composite, and records of L . macoupinense in earlier literature, including some of the type series, do not match the lectotype and are instead referable to L . birkmanni . The name L . macoupinense is still in use, but study of the lectotype shows it to be a senior synonym of the bee widely known (e.g., Mitchell 1960 ; Hurd 1979 ; Moure & Hurd 1987 ) as Evylaeus divergens (Lovell) (see below). Observed nesting in the ground in Alabama (see Gibbs et al. 2013 ).
