New records of Chironomidae (Insecta, Diptera) in the fauna of the Lower Dnipro, Ukraine

Key Points

Twenty-four species of Chironomidae were recorded for the first time in the Lower Dnipro region and Dnipro-Buh Estuary.
Key species include Xenopelopia falcigera, Tanytarsus pallidicornis, and T. usmaensis, marking significant biodiversity expansion.
Observations based on larval and pupal specimens collected in field studies within the region.
Findings stress the importance of identity in local fauna, prompting further ecological assessments.

Abstract

Based on the larval and pupal specimens 24 species /morphotypes of Chironomidae (Insecta, Diptera) are recorded for the first time in the Lower Dnipro region and Dnipro-Buh Estuary: Xenopelopia falcigera (Kieffer, 1911), Corynoneura scutellata Winnertz, 1846, Cricotopus (Isocladius) intersectus (Staeger, 1839), Hydrobaenus lugubris Fries, 1830, Limnophyes sp., Orthocladius (Euorthocladius) sp., Psectrocladius (Psectrocladius) sp. cf. zetterstedti Brundin, 1949, Chironomus (Camptochironomus) pallidivittatus Malloch, 1915, Ch. (Ca.) tentans (Fabricius, 1805), Ch. (Chironomus) cingulatus Meigen, 1830, Ch. (Lobochironomus) dorsalis Meigen, 1818, Demeijerea rufipes (Linnaeus, 1761), Dicrotendipes lobiger (Kieffer, 1921), Kieff erulus tendipediformis (Goetghebuer, 1921), Polypedilum (Polypedilum) nubifer (Skuse, 1889), Zavreliella marmorata (van der Wulp, 1858), Paratanytarsus inopertus (Walker, 1856), Pa. quintuplex Kieffer, 1922, Tanytarsus medius Reiss & Fittkau, 1971, T. pallidicornis (Walker, 1856), T. usmaensis Pagast, 1931, T. sp. cf. excavatus / nemorosus, T. sp. cf. formosanus Kieffer, 1912, T. sp. cf. lugens / glabrescens-type. Three species (X. falcigera, T. pallidicornis, T. usmaensis) and two morphotypes (T. sp. cf. formosanus, T. sp. cf. lugens / glabrescens-type) are recorded for the first time in the fauna of Ukraine.
