ABSTRACT
ABSTRACT The small mayfly genus UlmeritusTraver, 1956 currently includes three species of Neotropical Leptophlebiidae (Ephemeroptera) distributed in southern South America in the Pampean and Atlantic Forest dominions: U. carbonelli (Uruguay), U. balteatus (Brazil and Uruguay) and U. saopaulensis (Brazil). Ulmeritus saopaulensis is a poorly known endemic species from Brazil. Based on material from a single locality in Minas Gerais, we complement the knowledge on this species with a redescription of adults and nymphs and describe the eggs for the first time. The confusing nomenclatural history and the correct spelling of the specific name saopaulensis is discussed in light of International Code of Zoological Nomenclature. This paper points out that in despite of recent advances on the knowledge of this genus a full taxonomic review and phylogenetic analyses are pending to solve species delimitation and evolutionary relationships.
ABSTRACT
Abstract Leptophlebiidae is the family with the most diversity of species and wide distribution in the Southern Hemisphere. There are 95 species of Leptophlebiidae recorded in Brazil, but for the state of Bahia there are only 21 species. A check list and new records of Leptophlebiidae (Ephemeroptera) are presented to the State of Bahia. A total of 16 genera and 40 species of Leptophlebiidae were identified on this study. The species Fittkaulus cururuensis, Hylister obliquus, Miroculis (atroari) duckensis and Miroculis (Ommaethus) froehlichi are reported for the first time to the State of Bahia, increasing the number of Leptophlebiidae species from 21 to 25. Now, the Bahia is one of the states with the largest number of Leptophlebiidae species records, behind only of the state of Espírito Santo which has 26 species of this family.
