Summary The yucca moths ( Tegeticula and Parategeticula ) are of great importance in studies of coevolution because of their obligate mutualism with their yucca hosts. Historically, three species of Tegeticula have been recognized. One of them, T. yuccasella , has been regarded as the pollinator of all but two yucca species, but morphological, molecular and biological data show that this is a large complex of monophagous and oligophagous species that differ greatly in their biology. It also includes derived ‘cheater’ species that do not pollinate their hosts and oviposit into fruits rather than flowers. Here the yuccasella complex north of Mexico is revised. The nominotypic pollinator species yuccasella is redescribed, and ten new pollinator species described: altiplanella , baccatella , carnerosanella, cassandra, elatella , maderae , mojavella , rostratella , superficiella and treculeanella . Two non‐pollinating cheater species are recognized. One such species originally misidentified as a Prodoxus species, then synonymised with yuccasella, is re‐erected as the non‐pollinating intermedia . In addition, the new non‐pollinator species corruptrix is described.
