The traditional method of classifying the twenty-one species within the South American genus Polythore has been relying on wing color patterns and male genital ligula shape. However, recent molecular research has shown that wing color patterns can vary significantly within some species, making it an insufficient means of species diagnosis by itself in some cases.
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…
During 2.5 months of intensive fieldwork in Colombia (departments of Cauca, Nariño, and Putumayo, South America) from January to March 2017, we visited 13 localities and collected 291 specimens of 68 species of Odonata, including 17 new records for the country. We report range expansions for several species assessed as data deficient or under some…
Phenes raptor is one of only two petalurid dragonflies with a documented non-fossorial larval lifestyle. There have been few reported observations of larvae and their habitat, and the behaviour and ecology of this unique South American species remain largely unknown. This paper provides a review of previously published and unpublished information, and new observations on…
In this synopsis all 50 species of the primarily neotropical genus Telebasis are keyed, diagnosed, and illustrated. Helveciagrion is considered a junior subjective synonym of Telebasis, T. coccinata a junior subjective synonym of T. coccinea, and T. limoncocha a junior subjective synonym of T. griffinii. Six new species from South America are described: T. carvalhoi…
Tukanobasis huamantincoae sp. n. (holotype ♂: Peru, Loreto Región [MUSM]) is described and illustrated. Males of T. huamantincoae can be distinguished from T. corbeti by the presence of postocular spots and antehumeral stripes, the absence of apical brown wingspots, smaller number of postnodals, shorter CuA, …
Inpabasis intermedia sp. n. (holotype ♂: Peru, Loreto Región) is described and illustrated. An illustrated key to both sexes is given for all members of the genus. Males of I. intermedia can be distinguished from its congeners by the angled division laterally between dark and light areas of the pterothorax…
Nearly every dragonfly species around the world has now been assessed against the IUCN Redlist criteria revealing that 16% of species are at risk of extinction.
