| Summary: | Abstract. Aim is study of biological diversity of the Caspian coasts and islands ecosystems, the composition, especially geographical distribution and possible ways of forming of darkling beetles fauna (Coleoptera: Tenebrionidae).Methods. We used the traditional methods of collecting (hand collecting, soil traps, light traps), processing and material definition. List discussed tenebrionid fauna is composed using Abdurakhmanov and Medvedev (1994), Abdurakhmanov and Nabozhenko (2011).Results. The paper includes a comparative analysis of darkling beetles (341 species) of 17 regions of 5 Caspian countries. Diversity of Tenebrionidae of the Caspian islands Chechen (32 species), Tyuleniy (29 species), Nordovyi (24 species), Kulaly (16 species) is discussed for the first time. Faunistic base of discussed ecosystems includes species with turanian (sensu lato, 204 species), steppe (42 species), caucasian (30 species, including subendemics of the Caucasus), mediterranean (19 species), western asian (17 species) biogeographic complexes with background of widespread euro-siberian, transpalearctic, paleotropical species. Сonnections and relations of regional and island faunas are discussed.Main conclusions. Results of the study will be a step in the determination of age of the islands through the biological diversity and the coastal level regime of the Caspian Sea, as well as possible changes in the population structure of darkling beetles (Coleoptera: Tenebrionidae) on island ecosystems. |
