List of Odonates from Mata do Baú, Barroso, Minas Gerais, Brazil

Abstract

A survey of odonatofauna was carried out in Mata do Baú, a predominantly forested area in Barroso, Minas Gerais, regarded as a priority area for conservation and scientific investigation, as published by Biodiversitas, a Brazilian nongovernmental institution. Sample collection was conducted over twenty-six days from November 2009 to February 2011. Fifty-seven species of Odonata were collected and grouped into 30 genera and nine families. The dominant families were Libellulidae (46.5%), Coenagrionidae (20.6%), and Megapodagrionidae (10.3%). A specimen of Heteragrion obsoletum (Selys, 1886) was collected, which to-date is known by a single specimen collected in 1880 and red-listed as endangered. Special attention was given to the presence of five species of the genus Heteragrion, strictly limited to lotic forest streams, with two new species’. This genus is especially sensitive to environmental deterioration, indicating that the forest stream’s environmental conditions are beneficial to the area and create a baseline for future monitoring of similar environments.

List of Odonates from the Floresta Nacional de São Francisco de Paula (FLONA - SFP), with two new distribution records for Rio Grande do Sul, Brazil

“…In temperate regions of northern Europe, specifically southern and central Sweden, several studies have reported a regional species pool of between 24 and 30 (Wittwer et al 2010;Flenner & Sahlén 2008). According to studies from Brazil, Pires et al (2013) found 30 genera of dragonfly larvae in the Jacuí River Basin; De , listed a species pool of 56, in central Brazi; Monteiro et al (2013), noted 32 species in Manaus, Amazonas; Anjos- Santos & Costa (2006), registered 77 species, from Rio de Janeiro; and Souza et al (2013) recorded 47 in Mata do Baú, Minas Gerais. Thus, 46 species fit well into the general pattern for a Subtropical zone, although there may be some additional rare species occurring in the region, the estimated indexes indicate that the size of the species pool is correctly estimated although up to ten more species might occur.…”

“…The Brazilian Odonata are still poorly described, despite a few publications with ecological approach, species lists are known only from São Paulo (Costa et al 2000); Espírito Santo (Costa & Oldrini 2005); Minas Gerais (Souza et al 2013) for Mata do Baú specifically; and Mato Grosso (Calvão et al 2014) this last one being restricted only to a small region of the state. The most recent Odonata inventory for the state of Rio Grande do Sul is , for the central region, and Kittel & Engels (2014), from a nature reserve (Pró-mata/PUCRS), with sampling performed only in open areas in forest surroundings and restricted to the Zygoptera suborder.…”

Preliminary dragonfly (Odonata) species list from the Pampa biome in Rio Grande do Sul, Brazil, with ecological notes for 19 new records for the State

“…According to Kompier (2015) it can be overlooked due to its secretive habitats, which was proven true by our sampling experience. According to Heckman (2006) this species occurs in almost all southern American countries, and in Brazil there are records from CE (Takyia et al 2016), RJ (Assis et al 2004, Kompier 2015, MG (Souza et al 2013, Bedê et al 2015 and SP (Costa et al 2000). Burmeister, 1839 (Libellulidae) This forest species was found only in well preserved environments, such as small forest fragments, in shaded areas or natural clearings (at fallen trees), perching on dry twigs above the water.…”
