Context 1
... total of 1,708 specimens from 9 families, 43 genera and 84 species were collected and identified. The species list, sampling sites, new records of occurrences for the state of Paraná, and specimens reared (adults emerged in the laboratory) are presented in Table 2. The AF area was predominantly lentic, and TF sampling sites were mainly lotic, except for lentic or semi-lentic habitats such as the "Natural pool" (see Table 1, sampling site 16, Fig. 7). ...Context 3
... aspects allow the occurrence of a unique faunal composition with some well-established abundant species, such as Lestes auritus Hagen in Selys, 1862, Oxyagrion simile Costa, 1978, Erythrodiplax acantha, and Erythrodiplax castanea (Burmeister, 1839. Notably, this faunal group is composed of 14 species with lentic habitat preferences ( Table 2) that also occur in the AF area, including eight exclusive species and three that occurred in neighboring TF sampling sites. ...Similar publications
The old Odonata (dragonflies and damselflies) collection of the Sarawak Museum has been examined and re-identified. An annotated list of the species and specimens present in the collection is given, along with remarks about the locations where they were collected.
The surveys carried out in the years 2019-2021 permit to improve the knowledge of the dragonflies of the Special Protection Area IT1202020 "Mont Avic and Mont Emilius" (Aosta valley). New populations of Somatochlora arctica and Leucorrhinia dubia were discovered. The new population of S. arctica is located in the Mont Avic Natural Park and represen...
This paper aims to list the odonates fauna associated with rice fields and to study their behaviour in Sunwal, Central Nepal. Research was conducted from June to November 2019 in a rice field by establishing three study plots of (50×50) m2 each. A total of 33 odonata species (11 damselflies and 22 dragonflies) from six families were recorded. Six o...
Investigations on the diversity of Odonata in and around the Agricultural College and Research
Institute, Vazhavachanur, Tamil Nadu, India were studied. Eight locations were selected, of which sixteen Odonata species were recorded. In total, eleven dragonfly and five damselfly species were identified from Thiruvannamalai district, Tamil Nadu, India...
Katon-Karagai State National Nature Park is situated in the most elevated part of the Altai Mts so its territory is in general hostile for Odonata. Fifteen species of those were registered on three author’s week-long trips to the Park in 1987, 2010 and 2012. Of them, findings of Sympetrum meridionale were remarkable as this species occurs in the mo...

... Regarding the distribution of the two species that were recorded for the first time in Minas Gerais, E. chromoptera is known to occur in Paraná State (Borak, 2016) and Rio Grande do Sul State (Kittel & Engels, 2016) and M. venezuelae in Amazonas State and Paraná State (Araujo & Pinto, 2021). ...
Only 8% of the approximately 120 conservation units in Minas Gerais State collect information on the order Odonata, which motivated this study. We aimed to survey communities of this insect group in the Environmental Protection Area of the Machado River hydrographic basin, southern Minas Gerais State, Brazil. For this purpose, 12 areas were sampled by active searching from September 2018 to March 2019. Representatives of 71 Odonata species belonging to 8 families were collected. Seven species were found exclusively in this conservation unit, and two species were newly recorded for the state, namely Erythrodiplax chromoptera (Borror, 1942) and Micrathyria venezuelae De Marmels, 1989. This study surveyed the fifth richest odonatofauna in Minas Gerais State, underscoring the importance of the studied area for conservation of Odonata communities and necessitating actions for decreasing environmental impacts on this biological patrimony.
... Finally, we applied two bioindication tools to determine their accuracy in subtropical forest water system conversion. The first one was proposed by Oliveira-Junior and Juen (2019) Araujo and Pinto (2021). The region encompasses a wellpreserved area of the Atlantic Forest with many streams dammed to form two large reservoirs, maintained by the water and waste management company of the State of Paraná (SANEPAR), to supply water to Curitiba city and its metropolitan area ( Figure 1). ...
... All sampling events occurred on sunny days with each event lasting 3 h between 09:30 AM and 13:30 PM (time zone: UTCÀ03:00). The choice of the location of sampling sites was largely based on a former study (Araujo & Pinto, 2021), as well as on pilot collecting expeditions, considering the accessibility of sampling sites and the representation of the biota. The sampling sites described in Figure 1 were those that we considered more suitable to represent dragonfly communities in both MS and RP areas. ...

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.
In this study, we have comprehensively presented taxonomic information on all 62 known species of Heteragrion Selys, 1862, which includes illustrations, photographs, diagnostic characters, and a key to males. Our analysis is based on the examination of over 900 specimens from 19 different collections worldwide, encompassing the type material for at least 42 species. Furthermore, we have described a new species, Heteragrion corderoi sp. nov. (♂, BRAZIL, São Paulo state, Campos do Jordão, Condomínio Paradise, 24.i.1999, (Coordinates: -22.7072, -45.5894, 1796 m asl), F.A.A. Lencioni leg., LABECO), which we identified from a male that was previously considered to be a paratype of H. mantiqueirae Machado, 2006 and additional specimens collected in Campos do Jordão, São Paulo state.
Thraulodes marianoi sp. nov. is described, illustrated and diagnosed based on a single male imago from a subtropical forest at Pico do Marumbi State Park, in the protected area of Mananciais da Serra, state of Paraná, Brazil. Based on the dark coloration of legs and the large dark spot at base of forewing, T. marianoi sp. nov. is similar to species of the niger-group (Peruvian Amazonia) and to T. basimaculatus Giordano & Domínguez, 2005, a species endemic to Bolivia. The new species can be distinguished from all other species in the genus Thraulodes Ulmer, by the combination of following characteristics: (1) four cross-veins basal to bulla in forewing; (2) brown area covering about of proximal half of the forewing; (3) pleura violet; (4) middle and posterior femora yellowish washed with dark brown; (5) terga and sterna I-IV white washed with dark brown on posterior and lateral margin terga and sterna V-X dark brown; (6) penes short and wide with distolateral area, "ear-like" and poorly developed lateral pouch; (7) styliger plate triangular, median projection short and rounded on the apex. This new species represents the first record of the genus from the state of Paraná, Brazil.
