New occurrences of dragonflies in the Atlantic Forest fragments of Santa Teresa, Espírito Santo, Brazil

Abstract

One of the greatest obstacles to biodiversity conservation is the lack of information to prioritize efforts on practical actions. This lack of information comes mainly from absence of inventories in many areas where few groups have reasonably complete databases. The distribution of the dragonfly fauna of Brazil is little known -only 29% of the Brazilian territory presents data about the richness of Odonata. In this contribution, a database of Odonata species of Santa Teresa Municipality was built, Espírito Santo State, Brazil. The database has 627 specimens registered, 77 species distributed in eight families and thirty-eight genera, forty of these species are common, one endemic of the State of Espírito Santo, and nineteen endemic of Brazil. In relation to the measure of conservation, four species are present in the category Insufficient Data (DD), one present in the Nearly Endangered (NT) category, three species in the Vulnerable category (VU) and one in the category In Danger (EN). Twentyfive species are considered new occurrences for the city. These results suggest that the fauna of the studied region deserves attention and points to the interest in implanting future conservation units in the region of Santa Teresa municipality.

Check-list of the Odonata from the Sempre-Vivas National Park in the Cerrado region, Minas Gerais, south-eastern Brazil

“…The most abundant species in our study, Hetaerina simplex, has been recorded in the Atlantic Forest ( Silva & Souza 2020) and in the Cerrado in Minas Gerais ( Machado & Bedê 2015), as well as in the states of Espírito Santo ( Storari et al . 2019), Goiás ( Dutra & De Marco 2015), and Tocantins ( Cortês et al 2011).…”

“…and in the Cerrado in Minas Gerais(Machado & Bedê 2015), as well as in the states of Espírito Santo(Storari et al 2019),Goiás (Dutra & De Marco 2015), and Tocantins(Cortês et al 2011). It is a typical stream dweller, abundant in riparian forests and easily caught, factors that would explain its abundance in the SVNP.Endemic and rare species are often assessed within some degree of environmental vulnerability.…”
