     (from Boudot & al. 2009:150): Cordulegaster insignis is restricted to southeastern Europe and southwestern Asia. This species shows a strong regional variation in the yellow pattern, which has led to the description of various subspecies. However, the characters and the range of many subspecies are poorly known and some subspecies have yet to be described. The C. insignis group is currently worked. Cordulegaster mzymtae, which is found in the Pontic Alps in northeastern Turkey and in the southwestern Caucasian range, hybridizes with C. insignis and has recently be regarded as a dark subspecies of the latter. This taxon in locally threatened due to water extraction and pollution and may suffer from disiccation of springs as a consequence of climate change.

Die Kleinasiatische Quelljungfer, Cordulegaster insignis Schneider 1845, ist sehr variabel. Sie unterscheidet sich von C. picta vor allem durch ihr Verhalten: die Weibchen bleiben meist dem Wasser fern und kommen nur zur Eiablage in dessen Nähe. C. insignis hat zum Unterschied zu anderen Arten blaue Augen. Schneider & Schneider (2013) melden die Art (ssp. mzymtae) aus der Schwarzmeerregion östlich von Trabzon. 

Froufe & al. (2014) präsentieren eine Studie über genetische Untersuchungen an der Gattung Cordulegaster. Die bisher traditionell unterschiedenen Artengruppen haben sich auch genetisch bestätigt: "Although Odonata are a key component of many freshwater ecosystems, their taxonomy and evolutionary history is still far from being well resolved. In the present study, we report the first molecular phylogeny for the Western Palaearctic Cordulegaster genus (Odonata: Anisoptera: Cordulegastridae). We sequenced fragments of both mitochondrial and nuclear genes [cytochrome c oxidase I (COI) and Internal Transcribed Spacer-1 (ITS-1)] from eight species and 13 subspecies, from western, southern and central Europe, Turkey, and Morocco. Our data support the existence of two major groups corresponding to the traditional boltonii– and bidentata-groups. Both groups are monophyletic based on COI sequences and the distinctiveness of Cordulegaster princeps, Cordulegaster trinacriae, Cordulegaster picta and Cordulegaster heros relative to Cordulegaster boltonii, and Cordulegaster helladica and Cordulegaster insignis relative to Cordulegaster bidentata, is confirmed. All species are also monophyletic for ITS-1, with the exception of Cordulegaster helladica buchholzi, which shares the haplotype with C. insignis. Although moderate levels of genetic diversity were found within C. boltonii, there was no clear separation among the four subspecies, with the exception of the populations of Cordulegaster boltonii algirica from North Africa. Similarly, no genetic differentiation was found between the two subspecies of C. bidentata, Cordulegaster bidentata bidentata and Cordulegaster bidenta sicilica.."
