The Levant is a hot spot of biodiversity, even for Odonata. Approximately 90 Odonata species were recorded for the Levant and 48 from Lebanon. Lebanon, as a central part of the Levant, was visited in 2022 and 2023 for searching dragonflies.
Despite a high number of incidental online records of spiders predating upon dragonflies/damselflies, studies on these interactions are scarce. Here, we describe the predatory behavior of Argiope trifasciata on the two most common odonate species in the study area.
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.
Anormogomphus heteropterus is redescribed based upon a single male specimen. Discrepancies and inaccuracies in previous illustrations of this species that could cause confusion are pointed out. Platygomphus benritarum sp. nov. is described on the basis of a single male specimen collected at Tezpur, Sonitpur District, Assam, India.
An updated checklist of the 282 species of Odonata known to occur in Argentina is presented along with distributional information by province and ecoregion. Ten new records for the country and 87 new provincial records are provided. At present, 17 species of Odonata are considered endemic to Argentina, and distribution maps for each of them…
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…
The poorly known Ceriagrion mourae is redescribed based on the first material from Zambia and compared with the similar C. banditum, C. junceum and C. suave. Molecular data place C. mourae as a sister taxon to the clade (C. bakeri (C. banditum, C. junceum)). Genetic distances between the above-mentioned species are similar at c.7–9% (K2P)….
After observing the presence of Phylloicus pulchrus (Trichoptera: Calamoceratidae) and tadpoles of Leptodactylus albilabris (Anura: Leptodactylidae) on submerged leaves with recently laid eggs of Telebasis vulnerata (Odonata: Coenagrionidae), we set up an experiment to determine if they were consuming Odonata eggs. We collected leaves from the stream, where consumers were positioned over egg masses, and…
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…
Robust male condition must be favored and should be signaled to conspecifics via enhanced aggression and more highly expressed ornamental traits. One way that such robust condition, and thereby the expression of aggression and ornamental traits, can be assessed is via survival. In odonate adults, condition (in the form of lipid reserves, muscle mass and…
