Odonata of Itatira, a Brazilian semi-arid area in the state of Ceará

Abstract

The present study provides the first odonate survey for the Brazilian Caatinga, including species habitat information. Specimens were collected during five days in both dry and rainy seasons of 2011 in the municipality of Itatira, state of Ceará, located in the semi-arid region of northeastern Brazil. Adult individuals of 37 species were documented, the highest richness value thus far recorded for the region. Individuals of the majority of the species were recovered from small, temporary water bodies. In general, the local odonate community is composed of species with wide continental distributions, with the exception of Macrothemis lutea, M. griseofrons and Erythrodiplax leticia, which are restricted to northeastern Brazil. New occurrences and expanded distribution ranges of species are discussed.

Odonata (Insecta) community in the Environmental Protection Area of the Machado River hydrographic basin, southern Minas Gerais State, Brazil

“…The species I. capreolus, A. gracile, and O. terminale have wide distribution in Minas Gerais, occurring in different phytophysiognomies of the Atlantic Forest and Cerrado biomes (Dos Anjos, 2017) and being commonly found in lentic environments (Nobre & Carvalho, 2014;Vilela et al, 2016). Such environments are frequent in EPA-MRHB, explaining the abundance of these species in the present study.…”

Check-list of Odonata from the state of Bahia, Brazil: ecological information, distribution, and new state records

“…Of the nine states in the Northeast region, species lists are only available for four. Of the 69 species that appear as new records for the state of Bahia, only 11 were previously recorded in these states (Nobre & Carvalho 2014; Takiya et al 2016; Bastos et al 2019; Santos et al 2020; Koroiva et al 2021).…”

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

“…At first sight they were thought to be gomphids, due to the long abdomen (big overall size for a Macrothemis species) and general appearance. It is a rare species described from Brazil, known to occur in the state of SE which is the species type locality (Calvert 1909) and recently registered in CE (Nobre & Carvalho 2014). Here the distribution of the species is expanded southwards about 4,000 km.…”
