We registered 111 species from the region. The families with the highest number of species were Libellulidae (50 species), Coenagrionidae (43 species) and Gomphidae (12 species). 35 species are registered in the IUCN Red List species, four being Data Deficient, 29 of Least Concern and two species being in the threatened category. Phyllogomphoides suspectus Belle, 1994 (Odonata: Gomphidae) was registered for the first time in the state.

Palavras-chave: Libélulas, donzelinhas, Inventário, Cerrado, Brasil Introduction Bodoquena Plateau is a threatened area in the Mato Grosso do Sul state because of the broad conversion of natural areas to pastures and croplands Insects are arthropod group with largely unknown distribution patterns (Roque et al. 2016). In the last five years, several research projects about (Diniz-Filho et al. 2010), due to their high species richness, difficulties biodiversity and the ecology of aquatic insects have been developed in related to sampling and lack of taxonomic experts. Applying all of Bodoquena Plateau, (e.g. LTER Planalto da Bodoquena, Dragonflies of these conditions, odonates (Insecta: Odonata) constitutes an important Serra da Bodoquena Project and Observagua Project). These projects have group that play a major role as predators, with several insects making promoted a great opportunity for extending sampling effort of aquatic up a large portion of their diets. This group is also a good indicators of insects, especially for odonates (e.g. Koroiva et al. 2016, Rodrigues et al. water quality, with their nymphs being an important link in food chains 2016a, Rodrigues et al. 2016b, Valente-Neto et al. 2016). Until 2011, for fish and other aquatic vertebrates and serve as an inspired subject about 68 Odonata species were registered to Bodoquena Plateau; a number for artists, naturalists and collectors (Abbott 2015). that was considered underestimated because of the broad unsampled Even with important taxonomists in the recent Brazilian history, area (Dalzochio et al. 2011b). Therefore, even with the publications of odonates are still poorly described and its distribution is deficiently known checklists (Dalzochio et al. 2011a, Dalzochio et al. 2011b, Rodrigues & in the Neotropical region (Kalkman et al. 2008). Local inventories are Roque 2017), the amount of information generated by these new sampling recorded to several parts of Brazil like São Paulo (Costa et al. 2000), efforts and visits to museums demand an update. Espirito Santo (Costa & Oldrini 2005), Rio de Janeiro (Anjos-Santos & Here, we provide an updated checklist of the odonates from Bodoquena Costa 2006), Goiás and Distrito Federal (Nóbrega & De Marco 2011), Plateau, including species records from recent sampling efforts, from Minas Gerais (Souza et al. 2013), and Rio Grande do Sul (Renner et al. the literature, and from specimens deposited in the Reference Collection 2016). In Mato Grosso do Sul, state originally covered by Cerrado, of the Federal University of Mato Grosso do Sul (CEUFMS). We also Pantanal, Atlantic Forest and Chaco vegetation, 198 odonatan species were provide information about endangered species from the IUCN Red List registered (Rodrigues & Roque 2017). Despite this number, information (IUCN 2016), which is fundamental for updating the status of Brazilian gaps are recognized from many areas in this state (Vianna & De Marco species, as recently emphasized in the 1st Meeting of the Latin American 2012, Rodrigues & Roque 2017).

Material and Methods The dataset used in this checklist included 85 lotic environments (Figure 1) sampled during the period between 2011 and 2016. These samples were 1. Sources of data concentrated on adults from Odonata and were performed during Ph.D studies (Valente-Neto 2015, Rodrigues 2016), Long term ecological research We used different sources of information to produce the checklist, in the Bodoquena Plateau (LTER-Serra da Bodoquena), Dragonflies of Serra including samplings (from 2011 to 2016), previous available records on da Bodoquena Project and Observagua Project. The sampling method used literature and information collected in zoological reference collections of handhold insect nets, in sunny days, during the peak time of Odonata activities the Mato Grosso do Sul state. For each source, we searched for names (between 09:00 h to 16:00 h). The collection authorization process was and geographic coordinates of the locations. For records that did not have issued by IBAMA, through SISBio system under the number 41313-3 and latitude and longitude values, geographic coordinates of the centroid of 54386-1.

  • ABSTRACT Gregarine Parasitism in Dragonfly Populations of Central
    ABSTRACT Gregarine Parasitism in Dragonfly Populations of Central Texas with an Assessment of Fitness Costs in Erythemis simplicicollis Jason L. Locklin, Ph.D. Mentor: Darrell S. Vodopich, Ph.D. Dragonfly parasites are widespread and frequently include gregarines (Phylum Apicomplexa) in the gut of the host. Gregarines are ubiquitous protozoan parasites that infect arthropods worldwide. More than 1,600 gregarine species have been described, but only a small percentage of invertebrates have been surveyed for these apicomplexan parasites. Some consider gregarines rather harmless, but recent studies suggest otherwise. Odonate-gregarine studies have more commonly involved damselflies, and some have considered gregarines to rarely infect dragonflies. In this study, dragonfly populations were surveyed for gregarines and an assessment of fitness costs was made in a common and widespread host species, Erythemis simplicicollis. Adult dragonfly populations were surveyed weekly at two reservoirs in close proximity to one another and at a flow-through wetland system. Gregarine prevalences and intensities were compared within host populations between genders, among locations, among wing loads, and through time. Host fitness parameters measured included wing load, egg size, clutch size, and total egg count. Of the 37 dragonfly species surveyed, 14 species (38%) hosted gregarines. Thirteen of those species were previously unreported as hosts. Gregarine prevalences ranged from 2% – 52%. Intensities ranged from 1 – 201. Parasites were aggregated among their hosts. Gregarines were found only in individuals exceeding a minimum wing load, indicating that gregarines are likely not transferred from the naiad to adult during emergence. Prevalence and intensity exhibited strong seasonality during both years at one of the reservoirs, but no seasonal trend was detected at the wetland.

The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with edjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2.

The larva of E. media can be distinguished from other species of Erythrodiplax by the presence of lateral spines on S8 and S9, the number of premental setae (n = 22), palpal setae (n = 7) and by the mandibular formula. We also provide a preliminary key to known South American larvae in the genus. Keywords: Brazil; coastal wetlands; dragonfly; exuvia; Anisoptera Introduction Erythrodiplax Brauer, 1868 is an American genus that includes 60 species (Schorr & Paulson, 2017), of which 40 are known to occur in Brazil (Pinto, 2017) and 18 are hitherto reported from the state of Rio Grande do Sul (Consatti, Santos, Renner & Périco, 2014;Costa,1971; Hanauer, Renner & Périco, 2014; Kittel & Engels, 2016; Renner, Périco & Sahlén, 2013, 2016; Renner, Périco, Sahlén, Santos & Consatti, 2015; Teixeira, 1971).
