Abstract
Two species of chrysaugine moths, discovered as a result of an ecological study in Brazil of tree sloths and their ectoparasites, are described as new and named Cryptoses waagei sp. n. and C. rufipictus sp. n. They are differentiated from their single congener C. choloepi Dyar and near relatives Bradypophila garbei Ihering and Bradypodicola hahneli Spuler which are also found on tree sloths.
