During a period of nine years, from 2000 to 2008, two consecutive studies—one focusing on observations of adult Odonata, the other on collection of larvae—were carried out in the basin of the Guadiamar River in the southwestern Iberian Peninsula. In addition to monitoring Odonata, several environmental variables were assessed, including an index based on macroinvertebrate…
The Odonata checklist of continental Portugal, Madeira and the Azores includes 65 species. Besides Sympetrum nigrifemur, an endemic of Madeira and the Canary Islands, and the unique population of the Nearctic Ischnura hastata in the Azores, the species composition reflects a higher proportion of western Mediterranean and Ethiopian elements than any other European country. An…
An overview is given of the present knowledge and current research on the Odonata fauna of Turkey, Iran, and the Caucasus. The occurrence of endemic taxa and of rare and possibly threatened species is discussed. The use of water from various aquatic habitats is reviewed in order to gain insight in existing and potential problems,…
Thirty-five dragonfly species are reported from Mongolia and Inner Mongolia. Three are first records. A non-parametric test is used to determine the total number of species to be expected. It suggests that the current number of 62 may be asymptotically complete, except for some specific zones like the Bulgan valley in the south-west, and the…
New information shows that S. sinaiticum, is not divided into subspecies, as hitherto supposed. The subspecific name tarraconense, Jödicke, 1994 must be regarded as a junior synonym of sinaiticum., In contrast, the name arenicolor, Jödicke, 1994 denotes a taxon at full species rank, characterized by its larval and ligula morphology. This species is taxonomically identical…
The range of Macromia splendens, a rare anisopteran, includes SE France and some scattered localities on the Iberian Peninsula. During 1996-1998, I made an exhaustive search for the characteristics of the species’ larval and adult habitat, flight period and adult activity in NW Spain. Nine populations were found, greatly increasing its known range. Adults were…
