Two new species of the heptageniid mayfly genus Afronurus Lestage, Afronurus meo sp. n. and Afronurus mnong sp. n., are described from Vietnam with line­drawings of key characters. The larvae of A. meo can be characterized by rowed minute spines in the posterior margin of the abdominal terga 1­9 and distinct markings on anterior head, dorsal femora, and abdominal terga. The larvae of A. mnong can be characterized by scattered simple stout setae on the anterior margin and dorsal surface of femora, rowed acute spines on the posterior margin of abdominal terga 1­9, and plain brown body color. Their diagnoses, material data, distributions, and habitat and biological data are provided.
