Apobaetis insolitus n. sp., Apobaetis kallawaya n. sp. and Apobaetis niger n. sp. (Ephemeroptera: Baetidae) are described from nymphs collected in Argentina and Bolivia. Apobaetis insolitus can be distinguished by the labrum with anterior margin with a U-shaped emargination, segment II of labial palpi with triangular apically rounded distomedial projection. Apobaetis kallawaya can be distinguished by segment II of labial palpi with triangular, slender and apically pointed distomedial projection, the posterior margins of the abdominal terga with blunt spines and paraprocts with blunt spines apically. Apobaetis niger can be distinguished by the anterior margin of labrum with medial lobe and segment II of labial palpi with triangular apically rounded distomedial projection. The three new species possess tarsal claws with two rows of denticles. A key to all species known from nymphs is presented.
