RESUMO
The genus Miroculis Edmunds, 1963 (Ephemeroptera: Leptophlebiidae) is endemic to South American with 27 described species. In Brazil, 21 of these are known to occur. The present paper describes three new species of Miroculis Edmunds, 1963. Miroculis (Miroculis) botafora sp. nov. is described based on a male imago collected in a transition area between the Cerrado and Caatinga biomes in Piauí State, Brazil. Two species are described based on nymphs and adults: Miroculis (Miroculis) azevedoi sp. nov. and Miroculis (Miroculis) quilombola sp. nov.; both were collected in a Cerrado region of Maranhão State, Brazil. Additionally, new distribution records of Miroculis (Miroculis) fittkaui Savage & Peters, 1983 are provided.

Hermanellopsis Demoulin, 1955 is a genus of Leptophlebiidae known from adults of both sexes and is represented solely by two species, both from South America: Hermanellopsis arsia Savage Peters, 1983, described only from male subimago; and H. incertans (Spieth, 1943) described from male imago and female subimago. Edmunds et al. (1976) provided the generic description for the supposed nymph of Hermanellopsis. However, Savage Peters (1983) revised the genus, and study of related genera raised doubt about the identity of the proposed nymph. Thus, the nymph of Hermanellopsis has remained unknown until now.

Miroculis stenopterus, sp. nov., is described based on material from State of Pernambuco, Northeastern Brazil. The imago of the new species can be distinguished, among other characteristics, by an uncommon forewing shape, long and narrow, similar to species of genus Microphlebia. The tentatively associated nymph can be distinguished from other species of the genus mainly by the abdominal color pattern and the ratio of labial palp segment 2 to segment 1 (1.01-1.04 x).
