New records of dragonflies and damselflies (Insecta: Odonata) from Amapá state, Brazil

Abstract

The Odonata Order comprises one of the largest groups of aquatic insects, 7,000 species are described worldwide, with approximately 860 species registered in Brazil, around 14% of the global fauna known to date. However, there are still great gaps in the knowledge of Odonata fauna in many areas of Brazil. This study aims to present the results of the survey of Odonata species sampled in three counties in the state of Amapá. The state is located in the north of the country, inserted in the Amazon Biome. Odonata were caught between January and December 2018, with 472 specimens being sampled, belonging to seven families, 36 genera and 53 species. In total, 27 of the species found during the study correspond to new records for the state of Amapá. Due to the lack of information on the diversity of the Odonata order in Amapá, the list of species presented should serve as input for new studies contributing to the knowledge of the order in the state.

Diversity of the Anisoptera & Zygoptera (Odonata: Insecta) of Swat, Pakistan

“…Suborder Anisoptera comprised 74% (n=148) while suborder Zygoptera comprised 26% (n=52) of the odonate species with family Libellulidae the largest family. This pattern conforms to the overall abundance and diversity of odonate fauna worldwide as is evident from a recent report on the odonate fauna of Brazil (Garcia Junior et al, 2021). Some of the successful traits that make family Libellulidae the dominant family in diverse habitats worldwide include their ability to efficiently control their body temperature (Corbet & May 2008), adaptation to open vegetation environments (Rodrigues & Roque 2017), survival in human dominated habitats (Damaceno et al 2014) and a great dispersion potential (Oliveira-Júnior et al 2017).…”

Dragonflies and Damselflies in a region of the Triângulo Mineiro, Minas Gerais: checklist and taxonomic additions

“…The abundance and number of new records in our study were concentrated mainly on Libellulidae and Coenagrionidae. This result was expected, since these groups are represented by a great diversity of species present in numerous aquatic habitats in worldwide (Garrison et al 2006, Garrison et al 2010, and are commonly representative in Brazilian inventories (Souza et al 2013, Calvão et al 2014, Pires et al 2019, Garcia Junior et al 2021. Nevertheless, Aeshnidae and Gomphidae were slightly diverse in our study compared to other Cerrado inventories.…”

“…Many odonate species are known to be endangered with the overexploitation in many regions of the country (ICMBio 2018, Araújo et al 2020). This situation has encouraged great effort in preservation measures in the last years, including inventories in priority regions (e.g., Cerrado) and species conservation categorizations (De Marco & Viana 2005, Koroiva et al 2017, Dalzochio et al 2018a, Bastos et al 2019, Garcia Junior et al 2021, Koroiva et al 2020, Vilela et al 2020a. Despite this progress, distribution and taxonomic gaps are still frequently reported problems in the literature, even in explored regions.…”

Checklist of Damselflies and Dragonflies (Odonata) from Acre state, and the first record of Drepanoneura loutoni von Ellenrieder & Garrison, 2008 for Brazil

“…Despite this increase, only 29% of the Brazilian territory was surveyed so far, being a large part of these collections carried out in regions with more human and financial resources, such as the Southern, Southeastern and Midwestern regions (De Marco & Vianna 2005, Calvão et al 2016, Rodrigues & Roque 2017. In this sense, these studies, in addition to being insufficient, have a heterogeneous spatial distribution with a recent and slow increase in poorly sampled areas and which access is difficult, such as the Northern, (Koroiva et al 2020a, Garcia Junior et al 2021) and Northeastern regions (Santos et al 2021, Koroiva et al 2021.…”
