Odonata (dragonflies and damselflies) present an unparalleled insect model to integrate evolutionary genomics with ecology for the study of insect evolution. Key features of Odonata include their ancient phylogenetic position, extensive phenotypic and ecological diversity, several unique evolutionary innovations, ease of study in the wild and usefulness as(More)
Twenty one polymorphic microsatellite loci were isolated from two species of dragonfly (Odonata: Anisoptera), Macromia splendens (n = 8 loci) and Oxygastra curtisii (n = 13 loci). Both species have their main distribution areas in southwestern Europe, with records in the north of Africa in the case of O. curtisii. M. splendens is listed as vulnerable by(More)
We report the entire mitochondrial genome of the scarce blue-tailed damselfly, Ischnura pumilio (Odonata, Coenagrionidae), using next-generation sequencing on genomic DNA. A de novo assembly provided a single contiguous sequence of 15,250 bp that contained the A + T-rich region and all standard coding regions; gene configuration is similar to other odonates(More)
It has been postulated that obligate asexual lineages may persist in the long term if they escape from negative interactions with either sexual lineages or biological enemies; and thus, parthenogenetic populations will be more likely to occur in places that are difficult for sexuals to colonize, or those in which biological interactions are rare, such as(More)
Thelytokous parthenogenesis, the production of female-only offspring from unfertilized eggs, has been described in all the insect orders, but is a rare phenomenon in the Odonata (dragonflies and damselflies). The only-known case of parthenogenesis in this group is the North American damselfly species Ischnura hastata, which has parthenogenetic populations(More)
Both sexes of Hypolestes hatuey Torres-Cambas, sp. nov. (Odonata: Zygoptera: Hypolestidae) from Hispaniola are described and illustrated here. This newly described species differs from H. trinitatis and H. clara, the other two species within the genus, by the morphology of the genital ligula and male cerci. Females of H. hatuey sp. nov. differ from H. clara(More)
We report here the prevalence of parasitism by water mites (Arrenurus sp.) and terrestrial mites (Leptus killingtoni) on parthenogenetic Ischnura hastata (Odonata: Coenagrionidae) from the Azores islands. Leptus killingtoni was only found on the island of Pico, and the prevalence of infestation was highly variable among the different ponds studied, ranging(More)
Hypolestes (Odonata, Zygoptera) is a damselfly genus endemic to the Greater Antilles. The genus comprises three species: H. clara from Jamaica, H. trinitatis from Cuba, and H. hatuey from Hispaniola, which are currently evaluated by the IUCN as Endangered (EN), Vulnerable (VU) and Data Deficient, respectively. Here, we re-assess the conservation status of(More)
Species classification may not reflect the underlying/cryptic genetic diversity which should otherwise be conserved as it represents the potential of populations to evolve and adapt. The identification of evolutionarily significant units (ESUs) allows cryptic genetic diversity to be taken into account when designating conservation priorities. Here, we used(More)
The discovery of cryptic species (i.e. two or more distinct but morphologically undistinguishable species) has grown exponentially in the last two decades, due mainly to the increasing availability of DNA sequences. This suggests that hidden in the known species, many of which have been described based solely on morphological information, there might be a(More)
