Abstract
Abstract: The knowledge about the richness and distribution of Brazilian dragonflies is still being unveiled. Over the years, inventories, reviews, and descriptions have been made. These contributions, apart from the taxonomic value, also provide valuable data on the occurrence of species and their distributions, which are rarely accompanied by notes about natural history and behavior. Keeping this legacy in mind, we collected dragonflies between 2011 and 2019 in Minas Gerais state, which resulted in the registration of 90 species, 41 genera and 11 families. Our results also increase distribution data, an important tool for conservation actions, and provide additional information about habitat and biology of species.
Highlights
In the last 80 years, the efforts spent on taxonomic studies (Santos 1944, 1945, 1950, Machado 1964, 1985, Machado et al 1991, Lencioni 2005, 2006, 2017) and surveys (Dalzochio et al 2011, Calvão et al 2014, Vilela et al 2016, Koroiva et al 2017a, Koroiva et al 2017b, Rodrigues & Roque 2017) helped to cover gaps on knowledge of Brazilian odonates
The main objective of this study is to increase the knowledge of the geographical distribution of Odonata species
Odonata from West Minas Gerais small stream connected to a Vereda), Ponte 1 (PO1, -20.2402, -46.5875; small stream connected to a Vereda), Ponte 2 (PO2, -20.2325, -46.6083; small stream connected to a Vereda), Quintal da Canastra (QUI, -20.3282,46.5038; large pond), Cachoeira da Capivara (CPV, -20.6287,46.2863; large stream by a waterfall), Lago Tio Zezico (ZZC, -20.3121,46.5319; small pond), Córrego Tio Zezico (ZZC, -20.3116,46.5324; stream), Lago P31 (P31, -20.1656,46.6877; two small ponds within a Vereda), Riacho Sr
Summary
In the last 80 years, the efforts spent on taxonomic studies (Santos 1944, 1945, 1950, Machado 1964, 1985, Machado et al 1991, Lencioni 2005, 2006, 2017) and surveys (Dalzochio et al 2011, Calvão et al 2014, Vilela et al 2016, Koroiva et al 2017a, Koroiva et al 2017b, Rodrigues & Roque 2017) helped to cover gaps on knowledge of Brazilian odonates. Of the over 6000 hitherto described Odonata species, about 1700 are known to occur in the Neotropical region, and over 800 are recorded for Brazil (von Ellenrieder 2009, Neiss 2012) Despite these efforts, there are many species yet to be described. Calvão et al (2014) recorded five species new to Mato Grosso State, Brazil; Dalzochio et al (2018) reported 182 species and seven new records to the state of Rio Grande do Sul and Rodrigues & Roque (2017) recorded 33 species new for the state of Mato Grosso do Sul
