Odonata species diversity, distributions, and status in a rare sand prairie-savanna wetscape

Inland sand areas scattered across the North American eastern deciduous forest and western tallgrass prairie ecotone are known for supporting pyrogenic early-successional vegetation and specially adapted terrestrial faunas. Many of these globally and regionally rare systems contain functionally connected wetland networks (“wetscapes”) potentially important for aquatic insects.

Distribution, autecology, genetic characterization, and conservation of the Western Mediterranean endemic dragonfly Orthetrum nitidinerve (Selys, 1841): insights from Italy

Aquatic macroinvertebrates are a primary component of freshwater ecosystems and one of the most threatened by anthropogenic pressures. Among them, dragonflies are a charismatic group of growing scientific and social interest. However, little is known about the natural history of several species. One paradigmatic example is the declining Orthetrum nitidinerve, a Western Mediterranean endemic anisopteran….

Additions to the dragonfly genus Lauromacromia, with description of the female of Lauromacromia luismoojeni and new distributional records (Odonata: Corduliidae s.l.)

Taxonomic, morphological and distributional data on three species of the rare South American corduliid genus Lauromacromia Geijskes, 1970 are updated based on specimens collected recently and old specimens deposited in natural history collections. The female of the poorly known Lauromacromia luismoojeni (Santos, 1967), an endemic species from the Brazilian Cerrado, is illustrated, described and diagnosed…

An update on the distribution of threatened odonate species from the Greater Antilles

The Antilles harbour several island endemic odonate species, including some palaeoendemics, within a relatively small and anthropized area. Such attributes give this archipelago a special significance for the conservation of Odonata in the Neotropics. However, despite the importance of these islands, inadequately surveyed regions persist, mainly in the Greater Antilles, and there is not enough…

Checklist and updated distribution of Protoneuridae from Brazil

Protoneuridae are represented in the neotropics by 16 genera and 117 species, of which 64 species in 12 genera are known to occur in Brazil. Most of them are known only from the original descriptions or isolated records. During 2009 the Protoneuridae collection of MNRJ was revised; 2800 specimens were studied, belonging to 40 species…

Oligoclada mortis sp. nov. from Rondônia State, Brazil, and distributional records of other species of the genus (Odonata: Libellulidae)

Oligoclada mortis sp. nov. (holotype male deposited in MZSP: Brazil, Rondônia State, Porto Velho municipality, “T[ransect] 5-21, seg[ment]12” (09°35′19′′S, 65°02′50′′W, 106 m asl, 13 v 2010, leg. Nogueira & Mendes) is described and illustrated based on two males. The new species fits within Borror’s Group III, differing from all other described species in the genus by…
