Abstract.—Anchimacheta suppletella (Zeller, 1877), n. comb. (Lepidoptera: Urodoidea: Urodidae), is transferred from Blastobasis Zeller, 1855 (Gelechioidea: Blastobasidae). Anchimacheta suppletella is redescribed, and diagnostic features are given in support of the transfer. Anchimacheta suppletella is the ﬁrst species of the genus recorded from South America, and it represents the southernmost known distribution for the genus. Images of the imago and illustrations of the male and female genitalia are provided. A lectotype is designated for Blastobasis (Hypatima) suppletella Zeller, 1877. Key Words: adult morphology, Anchimacheta, Blastobasis, new combination, nomenclature, taxonomy, Urodidae DOI: 10.4289/0013-8797.120.2.245
