The 13 nominal species of the crassicornis group of Anaphes S.S. (previously known as Patasson) in North America are redescribed and keyed. Primary types are illustrated and the biology of several economically important species is summarized. Host-induced morphological variation is a problem in defining the species. Crossing experiments between nominal species reared from various economically important hosts are needed to determine whether similar morphological species are biologically distinct or not, as follows: Anaphes conotracheli reared from Conotrachelus spp. with A. pallipes reared from Cylindrocopturus adspersus and Rhagoletis pomonella; A. luna reared from Hypera spp. (especially H. postica) with A. victus reared from Listronotus oregonensis and with A. sordidatus reared from Tyloderma flveolatum; A. pullicrurus reared from Chaetoctema denticulata with A. cotei reared from Listronotus oregonensis.Molecular studies may also help resolve species limits. Hosts are still unknown for A. brunneus, A. confertus, and A. longiclava. A lectotype is designated for A. luna.
