Resumo
The mayflies spend most of their life cycle as nymphs in water bodies, but the adults are terrestrial and most species live for a few hours to a few days. Studies in water bodies of various orders in the Atlantic forest show how these organisms are diverse and abundant. Currently, this Biome in State of Espírito Santo occupy only 9% of its original cover. Conservation Units are fundamental tools for biodiversity conservation. However, often inadequate criteria are taken into account for creating Conservation Units. One of the criteria to be used for the indication is that they are located in an area of endemism. Several biogeographic methods have been employed to detect areas of endemism, such Parsimony Analysis of Endemism (PAE) and Network Analysis Method (NAM). The aim of this study was to identify priority areas for conservation in State of Espírito Santo from the data analysis of the order Ephemeroptera through biogeographic methods. Based on the literature and the specimens analyzed, the State of Espírito Santo now has recorded 112 species, 48 genera and nine families. Five genera, 14 species were recorded for the first time for Espírito Santo; eight species were recorded for the first time for southeast; and an exotic species (Cloeon smaeleni) were recorded for the first time for Neotropics. Moreover, we find 13 new species to science. Were defined for the State of Espírito Santo four areas of distribution of exclusive taxa. The results of three analyzes were largely congruent, PAE especially for being the same method. Two of four areas of distribution of exclusive taxa have six units each and the other two have only one conservation area. The areas of distribution of exclusive taxa to the south of the state are well represented by APCs, the same is not true for the north, which has only one APC. Therefore, it is recommended to increase the priority areas for conservation already exist for these contain the points distribution of exclusive taxa defined in this work.
