“…The common species, with wide geographic ranges, predominated in the areas of open vegetation, whereas the rarest and most important for conservation predominated in the forested area, a fact that corroborates the results obtained for the odonatological fauna of the Maraca Biological Reserve in Roraima (Machado et al 1991). In the Megapodagrionidae, five species of Heteragrion were collected, all from the gallery forest lotic streams.…”

A survey of odonatofauna was carried out in Mata do Baú, a predominantly forested area in Barroso, Minas Gerais, regarded as a priority area for conservation and scientific investigation, as published by Biodiversitas, a Brazilian nongovernmental institution. Sample collection was conducted over twenty-six days from November 2009 to February 2011. Fifty-seven species of Odonata were collected and grouped into 30 genera and nine families. The dominant families were Libellulidae (46.5%), Coenagrionidae (20.6%), and Megapodagrionidae (10.3%). A specimen of Heteragrion obsoletum (Selys, 1886) was collected, which to-date is known by a single specimen collected in 1880 and red-listed as endangered. Special attention was given to the presence of five species of the genus Heteragrion, strictly limited to lotic forest streams, with two new species’. This genus is especially sensitive to environmental deterioration, indicating that the forest stream’s environmental conditions are beneficial to the area and create a baseline for future monitoring of similar environments.

“…The anisopteran species Erythrodiplax castanea, E. fusca, E. juliana, Idiataphe amazonica, Micrathyria hesperis, Oligoclada abbreviata, and Tramea binotata were found predominantly at open areas. These species has a wide geographic range and predominate in open vegetation areas (Machado et al 1991, Costa et al 2000, Ferreira-Peruquetti & Fonseca-Gessner 2003, Souza et al 2013, Calvão et al 2014, Bedê et al 2015, Dutra & De Marco 2015, Takiya et al 2016, Rodrigues & Roque 2017. The large occurrence of these species at open areas consists mostly due to the fact that many anisopteran species can be considered fliers: tend to have larger body size and are able to produce endogenous heat, controlling their inner temperature, flying most of the time and regulating their body temperature by controlling haemolymph (Corbet 1999, Corbet & May 2008.…”

Those characteristics can be attributed to the mosaic of open areas, that favors the occupation by the fast and agile flying dragonflies (see Machado et al 1991). Considering the conservation perspective, those species could be less important in contrast with species found at shaded areas, which are less abundant, and have restricted distribution.…”

Dragonflies and damselflies (Insecta: Odonata) from a Cerrado area at Triângulo Mineiro, Minas Gerais, Brazil

Odonata is considered, among the aquatic insect orders, the second largest group in number of species. Its global richness is estimated in about 6,000 described species. The Brazilian richness represents around 14% of the world's odonatofauna, however, the knowledge on Brazilian dragonflies distribution is still poor. This study purpose an inventory of the dragonflies species present in aquatic habitats from a Preserved Area according to the Brazilian Forest Code, located in the Cerrado biome at Triângulo Mineiro, Minas Gerais. In the dry season, from April to June of 2017, we collected 680 specimens belonging to 36 species and six families. Among the collected species, Elasmothemis williamsoni was observed by the first time in Minas Gerais State, and we also found a new species of Tigriagrion (Zygoptera: Coenagrionidae) which is being described by taxonomists. Considering the fast agricultural advance over natural Cerrado systems, species lists can be important to define priority conservation areas for odonate species.

“…Lestes minutus Selys, 1862 Gerais. Some faunal studies in the Cerrado and other biomes have found species of Gomphidae to account for only 5% of the total odonate species richness sampled, while species belonging to Libellulidae generally dominated, which is a family known to have species with abundant and common populations (e.g., Machado et al, 1991;Ferreira-Peruquetti & Fonseca-Gessner, 2003). Nonetheless, the present study still found species of Libellulidae that had not been observed in previous inventories in Minas Gerais.…”

Dragonflies and damselflies (Insecta: Odonata) are widely distributed among freshwater ecosystems of tropical and temperate environments. They are also particularly sensitive to anthropogenic changes. The objective of this study was to inventory the odonate fauna of a section of the Sucupira Reservoir on Rio Uberabinha, Uberlândia, Minas Gerais, Brazil, and to document the species composition of the odonate fauna during the dry and rainy seasons. The study also aimed to describe the distribution of the sampled species in Brazilian states. Sampling took place in August and September of 2017 (dry season) and in February and March of 2018 (rainy season), and recorded 860 individuals of 43 species belonging to 26 genera and six families. Six new records representing the families Gomphidae, Libellulidae and Coenagrionidae were recorded for the state of Minas Gerais. Seventeen species were collected only during the rainy season and eight only during the dry season, while 18 species were found in both seasons. The rainy season had greater abundance, with four times as many individuals as the dry season. This study increases the number of records for Odonata in the Minas Gerais state, and reinforces the trend for greater predominance of this group during the rainy season in this biome.
