“…Additionally, Veredas are an important source of shelter and food from insects to fishes and birds, playing an important role on the ecological balance in the Cerrado. Odonates are little explored within such areas, despite recent studies show that this ecosystem holds a great number of species of the order (Vilela et al 2016;Barbosa et al 2019;Borges et al 2019).…”

The knowledge about the richness and distribution of Brazilian dragonflies is still being unveiled. Over the years, inventories, reviews, and descriptions have been made. These contributions, apart from the taxonomic value, also provide valuable data on the occurrence of species and their distributions, which are rarely accompanied by notes about natural history and behavior. Keeping this legacy in mind, we collected dragonflies between 2011 and 2019 in Minas Gerais state, which resulted in the registration of 90 species, 41 genera and 11 families. Our results also increase distribution data, an important tool for conservation actions, and provide additional information about habitat and biology of species.

“…Considering the knowledge gaps of Odonata in the Cerrado, we conducted an inventory in palm swamps and riparian forests of Marco 2015, Dalzochio et al 2018b), the most abundant libellulid in our study. However, even if anthropized areas are diverse in generalist dragonflies, they may contain not reported species with restricted distribution (Barbosa et al 2019, Santos et al 2020. In this context, we found Oligoclada xanthopleura and Angelagrion nathaliae in degraded ponds.…”

Remaining freshwater systems are historically under threat mainly due to human activities such as agriculture and urbanization. The consequences of such activities are innumerous, and among them there is a decrease of suitable habitats for threatened fauna. In the Brazilian Cerrado, the odonatofauna of palm swamps and riparian forests are still poorly explored, a fact that difficult conservation efforts of the group. Thus, we performed an inventory in several urban and rural sites containing these phytophysiognomies in Uberlândia, Triângulo Mineiro region, western Minas Gerais state. In total, we found 101 Odonata species, seven families and 46 genera in the municipality, with 76 and 66 species, respectively, belonging to palm swamp and forest sites. From this diversity, eight species were first records in the state of Minas Gerais: Neuraeschna claviforcipata Martin, 1909, Phyllocycla cf. medusaBelle, 1988, Diastatops intensa Montgomery, 1940, Oligoclada pachystigma Karsch, 1890, O. xanthopleura Borror, 1931, Angelagrion nathaliaeLencioni, 2008, Telebasis sanguinalis Calvert, 1909 and Telebasis simulacrum (Calvert, 1909). We also sampled Erythrodiplax anaGuillermo-Ferreira & Vilela 2016, a species listed as endangered (EN) by the IUCN red list. Additionally, we include some taxonomic notes of Forcepsioneura machadorum females, a newly discovered species in the region. Our results contribute to the Odonata database in Brazil and highlights the importance inventories in poorly explored aquatic ecosystems.

“…It is estimated that there are around 6.000 species described in the world and around 856 species cataloged in Brazil that leads itself to the greatest diversity in the world. 1,2 The increased taxonomic information that we have nowadays led to more studies about Odonata in Brazil considering how easy is to be observed and captured by the fascination created by this group. [3][4][5] Most of these surveys are about description of new species and their respective ecologic role 6 and geographic distribution.…”

The order Odonata is one of the most fascinating among insects, with an estimated 6,000 described species. Little is known about the Odonata fauna in many regions of Brazil; including Vereda’s areas. This unique plant formations occur only in Brazil. Despite being considered a preservation area, for over 70 years; there are a continuous degradation of this unique formation. The aim of this study was to survey the species of Odonata that occur in four areas of Veredas, within the urban perimeter of Uberaba/Minas Gerais. Two points were selected in the central region and two peripheral points. Four collections were carried out on sunny days, with two people intercepting the flight with entomological nets in May, September, December 2018 and March 2019. The total number of adults captured was 163. In the central points of the city we find generalist species, while in the peripheral points we find individuals endemic to Veredas and indicators of preserved environments. Data indicate that the Veredas have been severely abandoned by the Government and damaged by urbanization, and that the Odonata are an appropriate group to monitor the integrity of this type of environment, which gives rise to several important rivers in the region.
