The taxonomic status of the Central Asian damselfly Calopteryx samarcandica was determined on the basis of molecular and phenotypic data from the Kugitang Mountains, SE Uzbekistan.
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.
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.
The taxonomy and distribution of dragonflies of the genus Heliogomphus from the Western Ghats of southern India are discussed. A morphological study of fresh male specimens from the field, as well as holotypes and lectotypes from repositories was undertaken.
The final stadium larva of Philoganga vetusta Ris is described and illustrated in detail. The larva of supposed P. vetusta from Hong Kong is confirmed, and that of Philoganga sp. from Fujian can be determined to be P. robusta. The taxonomic characters and systematic status of the larvae of genus Philoganga are discussed and summarized….
The finnal stadium larva of Periaeschna zhangzhouensis Xu is described and illustrated for the first time. The taxonomic characters of the larvae of the genus Periaeschna Martin are discussed and summarized.
The final stadium larva of Leptogomphus elegans Lieftinck is described and illustrated for the first time. The taxonomic characters of the larvae of the genus Leptogomphus Selys are discussed and summarized.
The taxonomy of Chlorocypha species is problematic due to variability and the paucity of morphological characters. Subspecies radix of C. glauca is raised to specific rank. C. sharpae is found to be a synonym of C. luminosa. The synonymy of C. jejuna with C. luminosa is rejected. The former species is similar to the Southern…
A small inconspicuous spine, first detected at the base of the distal-most seta on each labial palpus of early stadia of two species of Enallagma, is reported to occur in final-stadium (F-0) larvae of Palaearctic and Nearctic E. cyathigerum, in F-0 of 31 other Nearctic species of Enallagma and in F-0 of three other coenagrionid…
A new damselfly species, Philogenia realpei sp. nov., is described here from 5 ♂♂, 2 ♀♀ collected at Cauca and Putumayo departments in southern Colombia. This species is included in the P. helena group and can be differentiated from other species by the unique morphology of its paraprocts.
