More than 400 scientific journal articles and gray literature reports that addressed macroinvertebrate drift were reviewed and 63 articles were found that reported on the natural drift of Odonata at some taxonomic level. Forty-three species and 44 genera within 15 families (nine Zygoptera; six Anisoptera) were documented in the drift. Drift of another 13 species…
The Odonata from the Refúgio Estadual da Vida Silvestre do Rio Pandeiros (RVSP), located in the Cerrado domain, Minas Gerais State, Brazil, were rapidly surveyed. Sampling efforts were undertaken along the Rio Pandeiros margins during four sampling periods between the rainy (spring–summer) and dry seasons (autumn–winter) from July 2014 to April 2015. We sampled 97…
Epiophlebia is the only known taxon of Odonata that is neither part of the damselflies (Zygoptera) nor dragonflies (Anisoptera). Previously, two species of Epiophlebia were recognized, restricted to areas in Japan (Epiophlebia superstes) and the Himalayas (Epiophlebia laidlawi). Recently, the group gained attention with the description of new species from China – Epiophlebia sinensis and Epiophlebia…
Aciagrion Selys, 1891 is one of the taxonomically difficult and poorly known genera of Oriental damselflies. Aciargion hisopa race krishna Fraser, 1921 was described from Mahabaleshwar, Maharashtra, India. However, later Fraser (1933) doubted the taxonomic necessity of this taxon. His notion of Aciagrion hisopa (Selys, 1876) was erroneous, as evidenced by syntypes of this species…
Microneura caligata (Hagen in Selys, 1886) is an endangered damselfly presently known from five localities in the central mountains of Cuba. The precise systematic position of this species within the former Neotropical Protoneuridae has been the subject of debate, with previous results from a phylogenetic analysis based on morphology suggesting that the genus Microneura should…
A survey of the Gomphidae of Algeria and the Maghreb was carried out during the period 2013–2014. Sampling of eight main wadis across northern Algeria was undertaken and adults and exuviae were recorded. The survey yielded six species of Gomphidae. Among these, we report on the rediscovery of the Critically Endangered Lindenia tetraphylla in Algeria,…
Our goal was to investigate whether the loss of riparian forests alters the structure of assemblages and populations of dragonflies and damselflies. We tested the hypothesis that the composition of the odonate assemblages found upstream from dams are significantly different from those found downstream of these barriers. To test the hypothesis, we investigated stream sectors…
The final instar larva of Heliaeschna idae Brauer is described and figured for the first time based on the exuvia from an advanced female larva collected in Sarawak, Borneo (East Malaysia). It is compared with the known larvae of the genus and is concluded to be most closely allied to Heliaeschna simplicia Karsch, with which…
A new species, Calicnemia soccifera sp. nov. (holotype male: Jinping, Yunnan, China) is described and illustrated for both sexes. C. miniata is confirmed to occur in Xizang (Tibet), China, and preliminary taxonomic remarks on some Chinese species of Calicnemia are given.
An updated checklist of known Odonata occurring in the Lesser Antilles is presented along with distributional information island by island. Twelve species are removed from previous listings and 16 new records are added, bringing the total number of species to 46. Of the new records, three correspond to the descriptions of new species and one…
