Species Notes

Viereck (1907) only mentioned this species in a key to females of Andrena likely to occur in Connecticut, but provided no description. Mitchell (1960: 139) examined the type material, and considered it a valid species, questionably refered to the subgenus Pterandrena Robertson, which was later placed in synonymy under Callandrena Cockerell by LaBerge (1964: 294). LaBerge (1967: 294) later removed this species from Callandrena to Plastandrena (though does not mention the type material), but subsequently did not treat it in his revision of that subgenus (LaBerge 1969). Although no specific comment was made about a “new synonymy”, the species was listed as a synonymy under A. crataegi Robertson by Hurd (1979: 1820) who is thus credited here. If A. angusi is indeed a Plastandrena, A. crataegi is the only species known to occur in eastern North America, including Connecticut, supporting the synonymy.
