Synonyms and other taxonomic changes
In a revision by Gibbs et al., 2013 in Zootaxa, many species traditionally classified as Evylaeus have been removed to expanded subgenera Hemihalictus (formerly monotypic) and Sphecodogastra (formerly included only Onagraceae specialists). In their new classification only L. cinctipes remains in subgenus Evylaeus.
