Chironomids (Insecta, Diptera, Chironomidae) from alpine lakes in the Eastern Carpathians with comments on newly-recorded species from Ukraine.

In total, 34 species/taxa, belonging to 22 genera and 4 subfamilies were collected in June 2019. Ten species were recorded for the first time in Ukraine: Zavrelimyia melanura, Acamptocladius reissi, Cricotopusspeciosus, Cricotopuscurtus, Heterotrissocladius marcidus, Orthocladius dentifer, Psectrocladiusoligosetus, Polypedilumuncinatum, Paratanytarsus laccophilus and Tanytarsus bathophilus. The occurrence of six species previously considered as "doubtfully present" in Ukraine was finally confirmed. Generally, the surveyed lakes have a unique composition of chironomids consisting of a mixture of species typical for cold alpine lakes and acidic ponds situated at lower altitudes.
