چکیده
We synonymize Hellichiella pugach Perkovsky & sukhomlin, 2015 with Gre niera yankovskyi Perkovsky & sukhomlin, 2015 (stegopterniini) based on the holotype and female paratype of H. pugach (stegopterniini). Hellichiella po lessica n. sp. differs from Hellichiella oligocenica (rubtsov, 1936) (the only species of Hellichiella known in Baltic amber) by its smaller body, narrower head, 11-segmented antenna, greater number of upper corneal facets, cylindrical metabasitarsus, and narrowed gonostylus. Our findings show three species of blackflies in Rovno amber: Greniera ukrainica Perkovsky & sukhomlin, 2015 and G. yankovskyi Perkovsky & sukhomlin, 2015 (stegopterniini) and Hel li chi ella polessica n. sp. (nevermanniini). KeywORds: rovno amber, eocene, simuliidae, Hellichiella, blackflies.
