CHIRONOMIDAE (INSECTA, DIPTERA) FAUNA OF THE LOWER DNIPRO. PART 2: SUBFAMILY ORTHOCLADIINAE
Анотація
The current work is the second part of a series of articles intended to describe the state of Chironomidae (Insecta, Diptera) fauna of the Lower Dnipro, based on the long-term studies of this family as part of the benthic, plankton and zoophytos communities and widely represented in the different types of water bodies of this area. This part of research is focused on the subfamily Orthocladiinae. The research was conducted on following water bodies, both the flowing and the standing waters, located in the delta and pre-delta areas of the Lower Dnipro: the Dnipro River, the Koshova River, the Viryovchyna River, the strait into Lake Bobrove, the strait into Lake Kruhle, the Hadiuchka Strait, the Chaika River, the Kozak River, Lake Liahushache, Lake Chychkuvate, Lake Skadovsk-Pohorile, Lake Stebliivskyi Liman, Lake Nazarove-Pohorile, Lake Zakitne, Lake Bobrove, Lake Kruhle, Lake Kardashynskyi Liman and Lake Sabetskyi Liman. Based on larval and pupal specimens, 14 species/taxa of the subfamily Orthocladiinae are recorded and described: Corynoneura scutellata Winnertz, 1846, Cricotopus (Cricotopus) bicinctus (Meigen, 1818), Cricotopus (Cricotopus) sp., Cricotopus (Isocladius) intersectus (Staeger, 1839), Cricotopus (Isocladius) cf. sylvestris (Fabricius, 1794), Hydrobaenus lugubris Fries, 1830, Limnophyes sp., Nanocladius (Nanocladius) dichromus (Kieffer, 1906), Orthocladius (Euorthocladius) sp., Propsilocerus lacustris Kieffer, 1923, Psectrocladius (Psectrocladius) cf. psilopterus (Kieffer, 1906), Psectrocladius (Psectrocladius) cf. sordidellus (Zetterstedt, 1838), Psectrocladius (Psectrocladius) cf. zetterstedti Brundin, 1949, Psectrocladius (Psectrocladius) sp. The biological and ecological characteristics of the Orthocladiinae species were given, including frequency indexes, indicators of quantitative development, seasonality, habitats, macrophytes association and abiotic factors. The distribution of widespread, common and rare species of the subfamily Orthocladiinae in the water bodies of the Lower Dnipro area have been determined.
