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…
Three new species of Ceylonosticta are described and illustrated: Ceylonosticta nancyae sp. nov., Ceylonosticta rupasinghe sp. nov. and Ceylonosticta alwisi sp. nov. from Samanala Nature Reserve (Adam’s Peak), Kuruwita-Erathna footpath, Ratnapura District, Sri Lanka. Ceylonosticta subtropica has been recorded for the first time after 83 years and the first depiction of its genital ligula is…
The larva of Papuagrion is described and illustrated for the first time based on two specimens collected near Goroka, Papua New Guinea. The larvae were identified by matching the mitochondrial marker COI with that of an adult specimen collected at the same locality. The larvae were found in the leaf axils of Pandanus trees which…
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 Previous unpublished records are provided for P. carnifex,…
The final larval stadium of four species of Cora are described and compared with known species in the genus. Cora skinneri Calvert, 1907, C. semiopaca Selys, 1878 and C. lugubris Navás, 1934 are described and illustrated for the first time using material from Costa Rica for the first two and from Colombia for the latter….
A synopsis is given of the knowledge of the genus Rhinagrion. The males of two new species are described from the Philippines: R. schneideri sp. nov. (holotype: Samar Island, Hinubangan, San Isidro, 31 March–5 April 1992) and R. reinhardi sp. nov. (holotype: Mindanao Island, Surigao del Sur, Carmen, 24 April 1995). Rhinagrion yokoii is synonymized…
Chalybeothemis chini sp. nov. from Pahang, Peninsular Malaysia, and C. pruinosa sp. nov. from Sarawak, Malaysian Borneo, are described from the male sex. The new species necessitate some redefinition of the previously monotypic genus, which is provided. The quiescent penis of Chalybeothemis is illustrated for the first time. Differences between C. chini, C. fluviatilis and…
Neurobasis awamena, a new calopterygid species from the southern highlands of New Guinea (holotype: Pimaga area, 6°30′S, 143°30′E, 27 vii 1994, deposited at Naturalis, Leiden) is described and figured. It is distinguished from the widespread N. australis by its longer legs, irregular teeth on the male cerci, and the sharp demarcation of the iridescent color…
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.
The traditional method of classifying the twenty-one species within the South American genus Polythore has been relying on wing color patterns and male genital ligula shape. However, recent molecular research has shown that wing color patterns can vary significantly within some species, making it an insufficient means of species diagnosis by itself in some cases.
