“…Ângelo Machado has made numerous contributions regarding odonates in many areas of Minas Gerais, including new findings and taxonomic descriptions of several species (see References for a list of new odonate species described by Machado from Minas Gerais since 1998). Other lists for different regions and biomes of the state have since been produced (Souza et al, 2013;Almeida et al, 2013;Bedê et al, 2015;Souza et al, 2017). Nonetheless, information regarding odonates is still lacking for Triângulo Mineiro, a region in the Cerrado biome, which is a world biodiversity hotspot (Myers et al, 2000).…”

“…The species of the family Gomphidae are known to secretive, many of which are also evasive, thus making them difficult to collect by the traditional method of entomological nets (Almeida et al, 2013). This may explain why few individuals of this family are sampled by inventories, and why three of four species of Gomphidae collected in the present study were new records for Minas 1,2,7,9,11,13,14,16,20,23,25,31,36,37 Cyanallagma angelae Lencioni, 2001 2,11,14,20,31,33,37 Epipleoneura venezuelensis Rácenis, 1955 X X 17 UB20180034 MG, MS, SP, RO, MT,GO,RJ,PR 11,12,16,20,23,30,31,33,34,35 Epipleoneura williamsoni Santos, 1957 X 2 UB20180035 MG, SP, AM, MT, GO, TO, BA 7, 11, 13, 16, 17, 20, 23, 37 Homeoura chelifera (Selys, 1876) X X 37 UB20180036 MG, RS, MS, SP, RJ, BA, ES, PR,SC 2,10,11,12,14,18,20,29,31,…”

“…Many studies of odonates in Minas Gerais have been carried out in the central and southern regions of the state (Souza et al, 2013;Almeida et al, 2013;Bedê et al, 2015), while other areas remain poorly sampled. For example, little is known about the odonate fauna of the Triângulo Mineiro Region in western Minas Gerais (e.g., Borges et al, 2019).…”

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.

BackgroundDiversity and distribution of Neotropical aquatic insects is still poorly known, with many species to be recorded and many others to be described, due to the small number of taxonomists and sparse faunistic studies. This knowledge is especially poor in the Caatinga Domain in Northeastern Brazil, even though, this region may have played an important historical role in the spatial evolution of faunas of forested areas in northern South America.New informationAquatic insect checklists of 96 species from Parque Nacional de Ubajara (Ceará State, Brazil) and 112 species from Parque Nacional de Sete Cidades (Piauí State, Brazil) are presented, representing the following taxa: Elmidae, Epimetopidae, Hydrophilidae, and Torridincolidae (Coleoptera), Hemerodromiinae (Diptera: Empididae), Ephemeroptera, Gerromorpha and Nepomorpha (Hemiptera), Odonata, Plecoptera, and Trichoptera. Because of the scarce number of biological inventories in Northeastern Brazil, several new distributional records (of species, genera, and families) for Brazil, Northeastern Brazil, and Ceará and Piauí states are provided. In addition, several undescribed species were detected, being 26 from Ubajara and 20 from Sete Cidades. Results represent a significant increase to the known fauna of these states, ranging from 13%-70% increase for Ceará and 41% to 91% increase for Piauí. Although both parks are relatively close to each other and within the Caatinga domain, their aquatic fauna display a very high complementarity (89% species), possibly due to structural differences of water bodies sampled in each park. Rarefaction curves based on quantitative light trap samples suggest a much higher expected species richness of aquatic insects at Sete Cidades than at Ubajara National Park. Discussion on biogeographical affinities of this sample of the Caatinga fauna is provided.

Influence of landscape homogenization due to river damming on dragonfly (Odonata) community structuring in a subtropical forest in the southern Atlantic Forest

Human activities affect the structure, dynamics and energy flow of aquatic ecosystems. River damming, a common anthropic impact in Brazil, changes solar incidence, water flow and temperature of waterbodies, thereby affecting their fauna. Due to their high sensitivity to environmental changes, the Odonata may be indicators of these impacts. We sampled two ecologically distinct sites, (1) a quasi‐pristine forested area and (2) a nearby human‐impacted reservoir landscape, to evaluate the effects of damming on odonate community structure. The species composition of quasi‐pristine communities was more heterogeneous and differed almost completely (indicating high turnover) from that of the reservoir‐area communities. The capacity of the reservoir to maintain local fauna was almost nil. The communities in the changed landscape had the highest local diversity, which is related to the high occurrence of widespread generalist South American species. We also tested two recently proposed bioindication ratio tools based on the richness or abundance of high‐level taxonomic categories; both effectively reflected the extent of the impacts of damming. The best performing ratios were Coenagrionidae/other Zygoptera richness ratio, Zygoptera/Anisoptera abundance ratio and Libellulidae/other Anisoptera richness ratio. The reservoir landscape promotes biotic homogenization. However, the water supply system entails the preservation of part of the native habitat in its surrounding areas, consequently maintaining forest‐dependent biodiversity in quasi‐pristine environments.
