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

Abstract

Remaining freshwater systems are historically under threat mainly due to human activities such as agriculture and urbanization. The consequences of such activities are innumerous, and among them there is a decrease of suitable habitats for threatened fauna. In the Brazilian Cerrado, the odonatofauna of palm swamps and riparian forests are still poorly explored, a fact that difficult conservation efforts of the group. Thus, we performed an inventory in several urban and rural sites containing these phytophysiognomies in Uberlândia, Triângulo Mineiro region, western Minas Gerais state. In total, we found 101 Odonata species, seven families and 46 genera in the municipality, with 76 and 66 species, respectively, belonging to palm swamp and forest sites. From this diversity, eight species were first records in the state of Minas Gerais: Neuraeschna claviforcipata Martin, 1909, Phyllocycla cf. medusaBelle, 1988, Diastatops intensa Montgomery, 1940, Oligoclada pachystigma Karsch, 1890, O. xanthopleura Borror, 1931, Angelagrion nathaliaeLencioni, 2008, Telebasis sanguinalis Calvert, 1909 and Telebasis simulacrum (Calvert, 1909). We also sampled Erythrodiplax anaGuillermo-Ferreira & Vilela 2016, a species listed as endangered (EN) by the IUCN red list. Additionally, we include some taxonomic notes of Forcepsioneura machadorum females, a newly discovered species in the region. Our results contribute to the Odonata database in Brazil and highlights the importance inventories in poorly explored aquatic ecosystems.

“…2017; Dos Anjos et al 2020; Gouvêa et al 2023). Only a study carried out in Uberlândia ( Vênancio et al . 2021) recorded higher richness, which may be due to the longer sampling period and use of different sampling methodologies.…”

“…Some studies have been conducted to understand the diversity of Odonata in the Cerrado of Minas Gerais ( Borges et al 2019; Dos Anjos et al 2020; Venâncio et al 2021) as well as in other Brazilian states ( Bastos et al 2019; Veras et al 2020). However, significant gaps exist in our knowledge of the taxonomy, diversity, and distribution of Odonata in the Cerrado .…”

“…There are about 900 Odonata species recorded in Brazil (Pinto & De Araujo, 2020), with Minas Gerais State having 324 species (Vilela, 2021). Checklist studies have been conducted in several locations and phytophysiognomies of the state (Table 1), including Poços de Caldas (Santos, 1966); Viçosa and Marliéria, in the Rio Doce State Park (Ferreira-Peruquetti & De Marco-Jr., 2002); Baú Forest, in Barroso (Souza et al, 2013); Serra do Cipó National Park (Almeida et al, 2013); Dragonflies Wildlife Refuge (Bedê et al, 2015); Itorotó Hunting and Fishing Club Ecological Reserve, in Uberlândia (Vilela et al, 2016); Serra do Papagaio State Park (Dos Anjos, 2017); Rio Pandeiros Wildlife Refuge (Souza et al, 2017); Bueno Brandão (Amorim et al, 2018); a stretch of the Uberabinha River in Uberlândia (Barbosa et al, 2018); Fazenda Nova Monte Carmelo, in the municipalities of Araguari, Estrela do Sul, Indianápolis, Nova Ponte, and Romaria (Borges et al, 2019); different localities of the western Cerrado biome (Vilela et al, 2020);Ibitipoca State Park (Dos Anjos et al, 2020); Inconfidentes, Ouro Fino, and Tocos do Moji (Silva & Souza, 2020); Cachoeira das Andorinhas Protected Area, in Ouro Preto (De Ávila Junior et al, 2020); Fernão Dias Environmental Protected Area (Stefani-Santos et al, 2021); and several localities on the outskirts of Uberlândia (Venâncio et al, 2021).…”

It is believed that the state of Pará, due to its dimensions and natural characteristics, has the possibility of occupying the second largest diversity of dragonflies in Brazil.…”
