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.
Polymorphism has rarely been reported from dragonflies of the Libellulidae (Odonata: Anisoptera) family. Here, we report female-limited polymorphism in females of five species of the Libellulidae and a gynandromorph male of Brachythemis contaminata from South Asia. We describe the morphological variation between andromorph and heteromorph females, and collate records of andromorph females from various sources….
The region covered is briefly defined and characterized as relatively little disturbed. A survey of relevant odonatological literature, including local Red Lists, is given, along with current scientific activity. Sixteen species are indicated, which deserve special attention, one of them, Ischnura aralensis, being the only strict endemic in the region. Some isolated populations deserving protection…
The conservation status of Odonata in the South Pacific Region and in Australasia is reviewed. Australian and New Zealand faunas have recently been monographed, for the rest of the region lack of data is the major handicap to concrete planning. The taxonomic status of the different island faunas and the state of habitat modification on…
Disjunct biogeographic patterns of similar species remain enigmatic within evolutionary biology. Disparate distributions typically reflect species responses to major historical events including past climate change, tectonics, dispersal, and local extinction.
Although Ischnura aurora (Brauer, 1865) was traditionally considered to be widely distributed in Asia, the populations west of continental China have recently been identified as equivalent to Ischnura rubilio Selys, 1876.
The global population structure and dispersal patterns of Pantala flavescens (Fabricius, 1798) are evaluated using a geographically extensive mitochondrial DNA dataset, a more limited samples of nuclear markers, wing isotopic (δ²H) data and a literature review. No spatial or temporal haplotype structure was recovered between the samples.
The genus Macromia is represented in Sri Lanka by two endemic species. In this paper a third presumed endemic species is described based on a single male specimen collected at Kirikitta, Weliweriya, Western Province in the low country wet zone of the country. Macromia weerakooni sp. nov. differs from its congeners in Sri Lanka by having turquoise blue eyes, an entirely black labrum…
Within the damselfly subfamily Platycnemidinae, eight species are currently recognized in South-East Asia. The final stadium larvae of only three of them have been so far described. The final stadium larva of Copera chantaburii is described and illustrated for the first time, based on reared specimens, and new provincial records both of larvae and adults…
The Bekko Tombo, Libellula angelina Selys, 1883 (Odonata: Libellulidae), is listed as an endangered species in South Korea, and is classified as a critically endangered species by the International Union for Conservation of Nature (IUCN). An assessment of the genetic diversity and population relationships of the species by molecular markers can provide the information necessary…
