Molecular phylogenetic analysis and its impact on the conservation of Ischnura rubilio Selys, 1876 (Odonata: Coenagrionidae) in Taiwan

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.

Tukanobasis huamantincoae, a new species of damselfly from Peru (Odonata: Coenagrionidae), with updated generic characterization

Tukanobasis huamantincoae sp. n. (holotype ♂: Peru, Loreto Región [MUSM]) is described and illustrated. Males of T. huamantincoae can be distinguished from T. corbeti by the presence of postocular spots and antehumeral stripes, the absence of apical brown wingspots, smaller number of postnodals, shorter CuA, ...

Morphological and molecular evidence supports the species status of the Italian endemic Coenagrion castellani Roberts, 1948 (Coenagrionidae)

Coenagrion castellani Roberts, 1948 was described from Italy as a distinct species almost 75 years ago but has generally not been recognised or was treated as a subspecies of C. mercuriale (Charpentier, 1840). Populations south of the Alps were recently shown to be completely isolated genetically from those in North Africa and elsewhere in Europe.

Factors influencing predation on Odonata by Argiope trifasciata (Forsskål, 1775)

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.

Effect of forest fires on a Mediterranean Odonata assemblage

Large-scale forest fires have shaped the Mediterranean landscape for millennia, causing a recurrent disturbance that constitutes a serious environmental issue. Following a devastating forest fire, changes in the Odonata larvae assemblage of a headwater stream were analysed during six consecutive years.

COI diversity supports subspecific division in Western European Lestes virens (Charpentier, 1825) (Zygoptera: Lestidae), but hints at further Mediterranean complexity

We analyse COI sequences of 48 specimens of European Lestes virens (Charpentier) to explore patterns in genetic diversity including subspecific boundaries and potential glacial refugia. Our haplotype network and phylogenetic analyses reveal three distinct groups in Western and Northern Europe.

A collecting trip to San José del Guaviare, Colombia, with the description of a new species of Perissolestes (Zygoptera: Perilestidae)

This study aims to preliminary assess the taxonomic diversity of dragonflies and damselflies from San José del Guaviare, Guaviare Department, Colombia. A total of 47 species were collected at five localities in different freshwater ecosystems during a field trip.

Territorial males have larger wing spots than non-territorial males in the damselfly Calopteryx splendens (Zygoptera: Calopterygidae)

Males of Calopteryx splendens use two alternative mating tactics, territoriality, and non-territoriality. These different mating tactics are shown to vary between males within the same population and previous studies have shown that territorial males have considerably higher fitness than non-territorial males.
