... Por exemplo, a família inclui Erythrodiplax Brauer que é 13º gênero mais rico da ordem e o segundo de Libellulidae, no Brasil estão registradas 41 espécies que corresponde a 67% das espécies deste gênero. Em gêneros como Macrothemis e Brechmorhoga, os erros de identificação são comuns, até mesmo naqueles relativamente bem estudados como Micrathyria (Fig. 15.101), Oligoclada, Orthemis e Perithemis, muito embora existam chaves, sinopses e revisões completas ou regionais (e.g., Ris 1930;Borror 1931;Santos 1953;Costa et al. 2002;Pinto & Lamas 2011b;von Ellenrieder 2012).

... For species identification, specialized taxonomic keys were used (e.g., Garrison et al. 2006Garrison et al. , 2009Garrison et al. , 2010Garrison et al. , 2015Von Ellenrieder 2012;Lencioni 2006Lencioni , 2017 and observed in stereomicroscope (Zeiss Stemi DV4), structures such as wing nerves, appendages of the abdomen, male genitals, chest and head structures. To confirm the identifications, the specimens were sent to the group experts, Dr. Frederico A. A. Lencioni and Alejandro del Palácio. ...
Odonata is amphibian insects, widely used in studies of aquatic ecosystems. In order for us to improve their use as bioindicator organisms, there is a need to increase our knowledge of how species distribution responds to the environmental gradient. Our study evaluates the relationship among habitat specificity, morphology and differences in spatial niche breadth of Odonata, in streams with different environmental conditions in the Cerrado Maranhense. We collected in 24 streams between May and November 2016 and March and April 2017. A total of 824 specimens were collected, distributed in 57 species, of which 12 were classified as generalists and five as specialists in integral habitat. Habitat generalists tend to be larger than species that specialize in intact environments; PERMANOVA showed a significant separation between the generalist and specialist groups in environments with less anthropic impact (Pseudo F = 0.173; p = 0.001). The length and width of the wings along with the length of the chest were the most important characteristics for this differentiation. Telebasis griffinii and Epipleoneura williamsoni (OMI – 0.0 and 5.0) presented the lowest spatial niche values. However, specialist species did not always show the lowest values. More than half of the species in our study (n = 35) were considered rare by the Multinomial species classification method (CLAM) for having an abundance of less than seven individuals. The number of rare species is a matter of concern given the fragmentation of the region's aquatic environments, which has been shaping Odonata assemblages, making room for generalist species and excluding species that need more complete conditions.
... Subsequently, the specimens were removed from the envelopes and placed on paper towels for drying by evaporation, and then they were stored in plastic envelopes on cardboard for identification, following the protocol by Lencioni (2005). Identification up to species or morph species was performed using specialized taxonomic keys (Lencioni, 2005(Lencioni, , 2006Garrison et al., 2006;Heckman, 2006Heckman, , 2008Garrison, 2009;Garrison et al., 2010;von Ellenrieder, 2012;Garrison & von Ellenrieder, 2015), and by comparison with the collection deposited at the Laboratory of Ecology and Conservation, Federal University of Pará. In addition, when necessary, specialists were consulted to review the identification or solve possible uncertainties. ...
the reduction of habitat integrity and canopy cover will lead to a lower richness of the Zygoptera sub-order, due to the restrictions of its thermoregulation and oviposition behavior in relation to Anisoptera, since the higher light input would favor heliother-mic and exophytic species; (3) alterations in habitat integrity create ecological thresholds and points of change in the abundance and frequency of Odonata species, generating gradients in the environmental integrity conditions. Specimens were collected from 24 streams (first to third order), in a gradient of land uses. Canopy cover and stream width were predictors of taxonomic richness and abundance of the subor-ders Anisoptera and Zygoptera, with greater coverage and smaller width, positively affecting Zygop-tera and negatively Anisoptera. The turning points were determined by a habitat integrity index, where below 0.38 there is an increase in generalist taxa and Abstract Aquatic ecosystems are affected by different land uses that modify gradients of environmental conditions. These impacts act directly on the community structure, especially the most sensitive ones, such as aquatic insects. Thus, dragonflies have been used as good models to assess these changes, since their suborders Anisoptera and Zygoptera have different ecophysiological and behavioral requirements. This study aimed to evaluate the following hypotheses: (1) dragonfly species composition differs along the environmental gradients of streams; therefore, we expect a higher proportion of species of the suborder Anisop-tera in environments with a higher degree of disturbance , since these environmental conditions select heliothermic species with exophytic oviposition; (2) Supplementary Information The online version contains supplementary material available at https:// doi. a decline in sensitive taxa. On the other hand, above 0.79, there was a sensitive taxa increase in detriment of generalists. Four individual taxa indicators were selected, two of which associated with a negative response (Perithemis tenera and Acanthagrion aepi-olum) and two with positive responses (Epipleoneura metallica and Zenithoptera lanei) for habitat integrity. Our results are important to guide management strategies, recovery, and protection policies for areas of permanent protection, aiming to conserving biodiversity and natural resources essential to life quality maintenance.
... The collection time and temperature were not reported for any of the specimens. Specimens were identified under a stereoscopic microscope (Nikon DS-Fi3), with reference to the keys by Garrison (1994), von Ellenrieder & Garrison (2003, Garrison et al. (2006Garrison et al.

Seven species of odonates new to Puebla and one to Morelos urban areas were identified from the entomological collection of the Universidad de las Américas Puebla (UDLAP), Mexico. Rarely observed species such as Argia extranea and A. westfalli were recorded in Puebla and Veracruz, respectively. Argia fumipennis, Ischnura demorsa, I. ram burii, Anax junius, and Triacanthagyna septima are discussed in detail. The ecological importance of the UDLAP campus, 'Flor del Bosque' State Park and Atlixco, is also noted. These records add to the knowledge of odonate distribution from Puebla, Morelos, and Veracruz.

The department of Ñeembucú, in southwestern Paraguay, is home to the virtually unexplored Ñeem-bucú Wetlands, the second largest wetland system in the country, representing a major gap in biodiversity knowledge. As organisms ubiquitous with wetlands, the Odonata, or dragonflies (Anisoptera) and dam-selflies (Zygoptera), have the potential to be effective indicators of wetland habitats in the face of increasing anthropogenic impacts in the region. We therefore comprehensively surveyed the Odonata in central Ñeembucú over a period of two years using a listing method. Here, we present an annotated checklist and identification key to the species present in central Ñeembucú with details on their habitat preferences, phenology and behaviour. We found 60 species but estimate a total of between 62 and 90 species. Eleven (18%) are new records for Paraguay. Species composition is similar to the Argentine Humid Chaco, with four bioregional endemics, whilst representatives from the Andean-Patagonian subre-gion are present in open areas. Such partitioning of species from different bioregions into different habitats is typical of ecotonal regions. Two further species are endemic to the Paraná-Paraguay basin and three are highly localised, indicating the high conservation value of the Ñeembucú Wetlands. Eleven species have the potential to be effective indicators of the Paraguay River, large permanent wetlands, grassy temporary wetlands and wooded temporary wetlands, providing an effective tool to identify critical wetland ecosystems in the face of the growing threats from human activities. We also provide recommendations for the protection and management of wetlands in the region.

... However, some species must be excluded from this list after revision of published records. For instance, the erroneous records of Neocordulia batesi batesi (Selys, 1871), Orthemis plaumanni Buchholz, 1950 andSkiallagma baueri Förster, 1906 have been corrected in the meantime (see Pinto & Carvalho 2011;Garrison 2012;von Ellenrieder 2012). In addition, records of species that are typical of the Amazon region, for instance Perilestes gracillimus Kennedy, 1941, Megapodagrion megalopus (Selys, 1862, and Acanthagrion apicale Selys, 1876 (see Kennedy 1941;De Marmels 2001;Machado 2012), and other species with dubious identifications due to insufficient taxonomic information, for example Heteragrion dorsale Selys, 1862, Heteragrion ovatum Selys, 1862, and Perithemis domitia (Drury, 1773), must be closely inspected and tentatively considered suspicious. ...
The dragonflies from the Parque Estadual da Ilha do Cardoso, municipality of Cananéia, located at the southern limit of the state of São Paulo in the Brazilian Atlantic Forest, were surveyed for the first time through a short sampling effort lasting four days in October 2011. A total of 36 species, including four new state records for species of the genera Lestes, Phyllocycla, Navicordulia and ‘Schizocordulia’, and three undescribed species of damselflies belonging to Cyanallagma, Forcepsioneura and Idioneura were identified. Some notes are also given for other species, as well as on the morphology and behavior of the intriguing corduliid Lauromacromia picinguaba (incertae sedis). The results, based on a small sample, indicate that the local dragonfly biota at Parque Estadual da Ilha do Cardoso is rich and impressive, and needs to be investigated and protected.
... Its value had already been demonstrated for other Libellulidae genera including Ery throdiplax Brauer, 1868(Borror 1942, Crocothemis Brauer, 1868(Lohmann 1981, Schnei der 1985, Orthemis Hagen, 1861 (Ellenrieder 2009(Ellenrieder , 2012 and Rhodothemis Ris, 1909(Kalk man & Orr 2014. The purpose of this study was to examine newly found characters of the male vesica spermalis and compare the results with traditionally used wing charac ters in order to see if agreement existed between the two sets of characters that would further aid in defining species. ...
Specimens of Neurothemis disparilis Kirby, 1889, N. fluctuans (Fabricius, 1793), N. fulvia (Drury, 1773), N. ramburii (Brauer, 1866), N. stigmatizans (Fabricius, 1775) and N. terminata Ris, 1911, including their subspecies, were studied with the main focus on the morphology of the vesica spermalis, wing maculation, wing venation, abdominal markings and vulvar scales. The results were compared with species descriptions and directly with type specimens where possible.
The vesica spermalis, especially the medial process, is useful at least in separating species groups and supports the traditional differentiation methods using wing maculation and venation. The use of other characters in accessing specific status, coupled with known distribution patterns, is discussed.
The following taxonomic changes are proposed: Neurothemis manadensis (Boisduval, 1835) stat. nov., Neurothemis papuensis (Lieftinck, 1942) stat. nov. and Neurothemis taiwanensis sp. nov. is described (27.5.1998, Kenting, Pingtung County/Taiwan, L. M. Juang leg.; holotype is deposited at Taiwan Forestry Research Institute, Taipeh, Taiwan). The type of Polyneura palliata Rambur, 1842 was rediscovered
at MNHN and designated as lectotype; a lectotype for Neurothemis nicobarica Brauer, 1867
housed at NHMW is designated. The holotype of Neurothemis incerta Brauer, 1867 was rediscovered
and synonymized with N. ramburii.

... Although some authors place this species in Hemianax (von Ellenrieder, 2002), we use Anax, as did Dijkstra and Lewington (2006), as relationships among the species in this genus are unclear at present (K-D. B. Dijkstra, personal communication). ...
... These two are the most likely odonates to be seen wherever water is present. The taxonomy of the Orthemis ferruginea group of species needs revision (Donnelly, 1995;von Ellenrieder, 2012), and there is no name to be applied unambiguously to this one, which could be called the "ABC" Orthemis. It may or may not be the same as a widespread red Antillean species that is also still unnamed (Donnelly, 1995) but is distinct from the recently resurrected O. macrostigma (Rambur) of the Lesser Antilles (Meurgey & Daigle, 2007). ...
... There are very few observations of the short-term colonization of islands by dragonflies, but Sibley (1999) reported the same phenomenon on much smaller Guana Island, an island without permanent water, in the British Virgin Islands. He found 10 species on that and nearby Anegada Island in October 1997, when a major storm passed through, but only three on the same island in October 1998, the same three that were present on Guana before the storm. ...
A three-year field study (January 2011–December 2013) of the Odonata of Curaçao, supported by photos and exuvial collections, recorded a total of 21 species from the island, almost doubling its previously known fauna. The lists of Odonata known from Aruba and Bonaire were also updated by specimen and photo records, and 24 species are now known from these three islands. During the period of the study, odonates decreased in abundance and diversity in Curaçao, apparently because heavy rains just before the study began led to colonization of the island by several nonresident species that subsequently declined and disappeared as wetlands diminished during a period with normal rainfall.
