Abstract

A review is given for the genus Obtusicauda Soliman in America north of Mexico. The subgenus Artemisaphis Knowlton and Roberts is restored to its original rank of genus. The species Obtusicauda essigi Soliman, O. jonesi (Gillette and Palmer), O. albicornus (Knowlton and Allen), and O. flavila (Knowlton and Allen) are considered to be synonyms of O. coweni (Hunter). The species O. cefsmithi (Knowlton and Allen) and O. zerohypsi (Knowlton and Allen) are considered to be synonyms of O. filifoliae (Gillette and Palmer). A key and an annotated list are given for the remaining six species of Obtusicauda.
