Miroculis lineage was initially proposed by Savage & Peters (1983)based on probable monophyletic relationshipamong four Neotropical genera: MiroculisEdmunds, 1963; MicrophlebiaSavage & Peters, 1983; HermanellopsisSavage & Peters, 1983; and Miroculitus(Needham & Murphy, 1924). Knowledge about last three genera has been poorly increased since their original description and most part of them are restricted only by type-series. Microphlebiais represented only by two species, as well as in Hermanella, and Miroculitusis a monotypic genus. On the other hand, Miroculisis one of the most specious genera of Leptophlebiidae South American with 18 valid species divided in four subgenera: Atroari, Miroculis s.s., Ommaethus, and Yaruma. Subgenera were supported by a relationship based basically by dorsal eye morphology. After main paper that treated to revise lineage, few knowledge about it has been performed. Even that, new species described allied to some remarks about morphological variations, have highlighteduncertainties about taxonomical identities of many species even of Miroculis’subgenera. Moreover, because most species are known mainly by one stage of development (mostly by adults stages), it is not possible understand their phylogenetic relationship since just part of semaphorontis known.Thus, goals of this thesis were to review taxonomyof Miroculislineage in addition to propose a first formal phylogenetic hypothesis about lineage, genus, subgenus and species. After analysis of type-series and additional material taxonomical results are: Promineogerousgen. nov.; Promineogerousconfusasp. nov., Miroculisauranticorpussp. nov., Miroculiscryptophallussp. nov., Miroculisexilibranchiasp. nov., Miroculispronexionsp. nov., Miroculisstenopterus(already published), and Miroculiswarbeastsp. nov.; Promineogerousarsianew. comb. Likewise, Microphlebiabecomes synonym of Hermanellopsis, and Microphlebia pallidaand Microphlebia surinamensisbecome synonym of Hermanellopsis incertans. Nymphs of Miroculis caparaoensisand Miroculis misionensisare described. About new phylogenetic hypothesis, monophyly of lineage is reaffirmed, but analyses were not recovered Miroculis’subgenera as monophyletic, so Savage & Peters’ proposal is refuted. Both taxonomy and phylogeny are so far to be well understated especially since it is necessary to know all stages of development.
