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…
Seventeen new dragonfly records from Colombia and the confirmation of the synonymy of Philogenia monotis and P. tinalandia (Insecta: Odonata)
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.

Larval habitat and behaviour of Phenes raptor (Odonata: Petaluridae): a review of current knowledge, with new observations
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 This paper provides a review of previously published and unpublished information, and new observations on…
A synopsis of the genus Telebasis (Odonata: Coenagrionidae)
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…
Inpabasis intermedia, a new species of damselfly from Peru (Odonata: Coenagrionidae); with an illustrated key to all known Inpabasis-species
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.

Re-description of the last instar of Remartinia luteipennis luteipennis (Burmeister, 1839) (Odonata: Aeshnidae)
The final instar of Remartinia luteipennis luteipennis (Burmeister, 1839) is described and illustrated based on reared specimens from Salta Province, Argentina. It is compared with R. secreta and R. l. florida, and with Calvert’s original description of R. l. luteipennis. Remartinia l. luteipennis can be differentiated by the length of the lateral valvae of the…

Most are found in the Amazonian lowlands; two are known from higher elevations in the Andes. From Brazil 26 species were known. In this article another Neotropical species is described,…
Phoenicagrion trilobum, a new species of damselfly from Peru (Odonata: Coenagrionidae)
Three species of Phoenicagrion are known from the north-eastern Amazonian part of Peru: P. flammeum, P. paulsoni, and a third undescribed species. In 2009 and 2010 several specimens of this third species were collected in Loreto, making it possible to describe this species, here named Phoenicagrion trilobum (holotype ♂: Peru, Loreto department, Tahuayo River, 18 km E…
Odonata biodiversity of the Argentine Chaco biome
Odonates of small temporary pools, marshes, large permanent ponds, oxbow lakes, dams, and perennial rivers were sampled in the semiarid Chaco biome of NW Argentina between September 2007 and December 2008. Information from 35 localities yielded 60 species; presence/absence information of species was recorded in a spatial-relational database. Alpha, beta, and gamma diversity and total…
