Putative hybrids between the sibling species Ischnura capreolus and I. cyane from the Colombian Cordillera Oriental are reported from the department of Cundinamarca, central Colombia, where species are known to occur sympatrically. Ischnura capreolus is quite widespread in South America, from sea level to 1 750 m a.s.l., while I. cyane is a Colombi...

... black and laterally blue (Fig. 3). Hind border of S10 with a large black spine with bifid tip projected posteriorly. Cerci black, hook-shaped, with distal half turned downward almost at a right angle. Paraprocts in lateral view pale with black tip, subquadrate, curving inwards forming a small C-shape at the end, not higher than the paraproct base (Fig. 2D). Genital ligula with distal segment narrow and deeply bifid, forming two curved spines slightly ...

... all individuals examined were hybrids from crosses between I. cyane and I. capreolus, we found a shape gradient that ranged from hybrids with the para proct morphologically close to I. capreolus to hybrids with the paraproct morphology close to I. cyane (cf. Figs 2D-E). In lateral view, the paraprocts of some hybrids had a pronounced "C-shape" terminally, similar to the I. capreolus paraproct (Figs 2A-C), in combination with the dark blue thoracic coloration (Fig. 3). ...

In lateral view, the paraprocts of some hybrids had a pronounced "C-shape" terminally, similar to the I. capreolus paraproct (Figs 2A-C), in combination with the dark blue thoracic coloration (Fig. 3). At the other extreme, some hybrids had long and a poorly defined terminal "C-shape" in the paraprocts, in combination with light blue thoracic coloration; that is, closer to I. cyane paraprocts shape (Figs 2F-H) and coloration (Fig. 3). ...

Background
Interspecific competition is known to be strongest between those species that are both closely related and sympatric. Egrets are colonially nesting wetland birds that often overlap and can therefore be expected to compete in roosting and nesting habitat as well as in diet. According to the niche partitioning hypothesis, it is to be expec...

Colombian odonatological history was scarce until two decades ago. Here, we present an updated, thoroughly vetted, and refined checklist of taxonomic and geographical records of Colombian odonates, built upon the previous publication in 2011. To achieve this, we conducted an extensive literature review, and curated the most representative biological collections of odonates in the country. Our goal was to integrate new records and recently described species, while excluding misidentifications or doubtful identifications due to a lack of support from taxonomic revisions and specimens in collections. We report a total of 536 species, reflecting a 38% increase in odonate richness since the last published checklist in 2011. This number positions Colombia among the top ten countries with the highest number of odonates worldwide. We include important taxonomic details for each species in the checklist, the availability of female and/or larva description(s), and the IUCN species assessment. We also highlight rare or puzzling species, which records for the country are controversial. It is noteworthy that the majority of these contributions stem from local Colombian research efforts that have enriched our national reference collections, including ANDES-E, CEUA, and UARC. Geographically, the department with the highest diversity is Meta with 205 species followed by Antioquia with 170 species. The latter holds the highest number of endemics across the country. We anticipate that this effort will be the basis and inspiration to future research on Colombian odonatofauna, especially in underexplored areas, and will encourage conservation initiatives for freshwater ecosystems across the country.
... Although natural hybridisation is thought to be somewhat uncommon in animals, individuals with exceptional phenotypical traits, morphological characteristics at the intersection of different species, or of "intermediate" phenotypes regularly occur in nature (Uthicke et al. 2005;Lutterschmidt et al. 2007;Galindo-Ruiz et al. 2019;Eshenroder et al. 2021;Liberman et al. 2021;Gaudiano et al. 2022). Such individuals are often considered as putative hybrids. ...
In this report, we analyze a wild-caught Colias specimen from Kyrgyzstan with unusual wing pattern, which was provisionally identified as a natural hybrid between Colias christophi helialaica Schulte, 1988 and Colias cocandica cocandica Erschoff, 1874 due to its intermediate phenotype. Using one mi-tochondrial (COI barcode) and three nuclear (Ca-ATPase, H3 and CAD gene fragments) markers, we confirm its hybrid origin and demonstrate that this specimen is a hybrid between a female of Colias christophi helialaica and a male of Colias cocandica cocandica. Our study shows that an analysis of mitochondrial and nuclear molecular markers can successfully discriminate natural hybrids in such a taxonomically challenging group of butterflies as the genus Colias.
This research-level text documents the latest advances in odonate biology and relates these to a broader ecological and evolutionary research agenda. Despite being one of the smallest insect orders, dragonflies offer a number of advantages for both laboratory and field studies. In fact, they continue to make a crucial contribution to the advancement of our broader understanding of insect ecology and evolution. This new edition provides a critical summary of the major advances in these fields. Contributions from many of the leading researchers in dragonfly biology offer new perspectives and paradigms as well as additional unpublished data. The editors have carefully assembled a mix of theoretical and applied chapters (including those addressing conservation and monitoring) as well as a balance of emerging (e.g. molecular evolution) and established research topics, providing suggestions for future study in each case. This accessible text is not about dragonflies per se, but rather an essential source of knowledge that describes how different sets of evolutionary and ecological principles/ideas have been tested on a particular taxon. This second edition of Dragonflies and Damselflies is suitable for graduate students and researchers in entomology, evolutionary biology, population and behavioral ecology, community ecology, and conservation biology. It will be of particular interest and use to those working on insects and an indispensable reference text for odonate biologists.
