A note on the rare dragonfly Davidioides martini Fraser, 1924, is provided with an update of its distribution range, status, ecology, and the description of its so far unknown female. This species is endemic to the Western Ghats of Peninsular India and seems to be a rare one.
Despite the important role of the order Odonata in ecosystems, there is a lack of information about dragonfly communities in several regions, high elevation sites, and environmentally protected areas in Minas Gerais State, Brazil. Our objective was to assess the abundance and richness of dragonfly and damselfly communities along an elevational gradient in the Atlantic Forest, southeastern Brazil.
Coeliccia diehlae sp. n. (holotype male from Ko Roong Commune, Ka Bang District, Gia Lai Province, Central Highlands of Vietnam, deposited in the Zoological Collection of Duy Tan University) is described based on both sexes. This species belongs to the pyriformis-group and comes closest to…
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…
Adult female and ultimate stadium larva of Mesagrion leucorrhinum are formally described and illustrated based on material from three locations in Antioquia, Meta and Cundinamarca Departments, Colombia. The species is sexually dimorphic. The ♀ is distinguishable from other related genera by a pair of notches in the prothoracic anterior lobe and shares with Heteropodagrion and…
The female of Mortonagrion ceylonicum is described and figured for the first time. The female was described briefly by Laidlaw (1924) but was not assigned to a genus or species. An amended description of the male is also provided. Additional notes on habitat, distribution and behaviour are given.
Heteragrion makiritare sp. nov. is described from two males from the Pantepui region – holotype: Venezuela, Amazonas State, Marahuaka, Sima (3°43′N, 65°31′W), 1,140 m a.s.l., MIZA, no. 17250. It belongs in the species group whose paraprocts are absent in the male sex. The identity of H. macilentum is elucidated by examining its lectotype and a…
The morphology of the hitherto unknown female of Somatochlora borisi is described and illustrated basing upon eight adults from Bulgaria, Greece and Turkey. A key is provided which allows the determination of the females of all West Palaearctic Cordulia and Somatochlora spp. A list of the presently known localities and a distribution map show the…
The final instar larva of Cordulegaster kalkmani Schneider, Vierstraete, Müller, van Pelt, Caspers, Ikemeyer, Snegovaya & Dumont 2021 is described and illustrated based on one female exuvia collected in Alakabük, Bitlis province, Turkey, in July 2022.
The Indian Elattoneura are a difficult group to identify due to their extreme morphological similarity and sparse information in identification keys and on geographical distribution. The ambiguity is prominent among two Peninsular Indian Elattoneura species, E. nigerrima (Laidlaw, 1917) and E. tetrica (Laidlaw, 1917), described a hundred years ago.
