Brazil hosts a wide range of Odonata species, including many hitherto unde¬scribed ones, especially in remote and unexplored regions where logistics are difficult. The northwestern Brazilian Amazon is an example of this situation, and many locations still need to be sampled there and have their taxonomic inventories compiled.
Damselflies of the genus Lestes Leach, 1815 are represented in India by 11 species. Using specimens collected over the last five years, we report on the rediscovery of Lestes nigriceps in India after 98 years, at two new localities in the Western Ghats.
Polymorphism has rarely been reported from dragonflies of the Libellulidae (Odonata: Anisoptera) family. Here, we report female-limited polymorphism in females of five species of the Libellulidae and a gynandromorph male of Brachythemis contaminata from South Asia. We describe the morphological variation between andromorph and heteromorph females, and collate records of andromorph females from various sources….
Tropical America is currently experiencing the establishment of a new apex insect predator, the Paleotropical dragonfly Hemianax ephippiger (Odonata: Aeshnidae). H. ephippiger is migratory and is suggested to have colonised the eastern Neotropics by chance Trans-Atlantic displacement. We report the discovery of H. ephippiger at three new locations in the Caribbean, the islands of Bonaire,…
Elasmothemis rufa sp. nov. (holotype: Venezuela, Amazonas, Río Cataniapo), Macrotbemis taurepan sp. nov. (holotype: Venezuela, Bolívar, El Paují), and Oligoclada garrisoni sp. nov. (holotype: Venezuela: Amazonas, San Fernando de Atabapo) are described and illustrated. All holotypes are deposited at MIZA. Macrothemis heteronycha and Micrathyria paruensis are recorded from Venezuela for the first time, and Micrathyria…

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…
Four new species of Palaiargia from New Guinea, P. benkeni, P. clarillii, P. quandti and P. tydecksjuerging, are described and figured. Maps are provided of the known distributions of all species of the genus which occurs in the Moluccas and on the main island of New Guinea. Previous unpublished records are provided for P. carnifex,…
This study aims to preliminary assess the taxonomic diversity of dragonflies and damselflies from San José del Guaviare, Guaviare Department, Colombia. A total of 47 species were collected at five localities in different freshwater ecosystems during a field trip.
