Abstract Gall midges are reported for the first time in Late Eocene Rovno amber from the Olevsk, Zhitomir Region. This is the second amber locality to yield gall midges in the Zhitomir Region, after Gulyanka. Rovnoholoneurus gen. n. and two new species, Rovnoholoneurus davidi sp. n. and R. miyae sp. n. are described. Bryocrypta laqueata Fedotova, 2005 is transferred to the genus Rovnoholoneurus, and Rovnoholoneurus laqueatus (Fedotova, 2005), comb. n. is established. A key to the species of Rovnoholoneurus is provided.

A new species of pincer wasps, Bocchus schmalhauseni sp. nov. (Dryinidae) is described from Rovno amber (Ukraine). The amber piece was collected in the Vladimirets District in the north-west of the Rovno region. Taking into account this new record, a total of five species of Dryinidae are registered from Rovno amber. A key to the fossil species of Bocchus Ashmead is presented. The possible reasons for the different distribution of Dryinus species on both coasts of Subparathetys are discussed.

In North America, Paleogene Verrucidae are rarely encountered. Only a single named species has been previously discussed by Zullo & Baum (1979), who provisionally assigned a Palaeocene form from North Carolina to Verruca rocana Steinmann, 1921. Eocene deposits in Washington State (USA) have now yielded two new species from intertidal to shallow water environments: Verruca gailgoedertae sp. nov. from the middle Eocene Crescent/McIntosh transition zone, and Verruca sorrellae sp. nov. from the upper Eocene to lowest Oligocene Gries Ranch and basal Lincoln Creek formations. Both species are characterized by punctate shell plates, and are placed in the lineage of Verruca stroemia (O.F. Müller, 1776). In Alabama, marls from the upper Yazoo Formation (Pachuta and Shubuta Members) have yielded Verruca alabamensis sp. nov., an uncommon deeper water form associated with abundant brachiopods and phosphate deposition. This last species shows no development of punctae and is not related to the lineage that leads directly to Verruca stroemia.

A new caddisfly species Plectrocnemia kirmikhia sp. nov. (Polycentropodidae) is described from Priabonian Rovno amber (Upper Eocene, 33.9–37.8 million years old). Now the family Polycentropodidae is represented in Rovno amber by 16 named species, and the genus Plectrocnemia includes 5 described species in this locality.

Abstract Study of five examples of spider beetle inclusions from Rovno amber revealed that at least three of these spider beetles belong to the genus Sucinoptinus Bellés et Vitali, 2007, of them, S. rovnoensis sp. n. (most probably from Klesov) and S. brevipennis sp. n. from Dubrovitsa are described. S. rovnoensis is similar to the previously known S. bukejsi Alekseev in having the same general structure of pronotum and elytra, differing from it by the morphology of pronotal sides, which are only slightly rounded and practically not constricted near the base, whereas in S. bukejsi the sides are well rounded leaving a slight but clear constriction near the base. S. brevipennis is similar to S. bukejsi Alekseev and S. sucini Bellés et Vitali in having the same general structure of the prothorax, but differing from them in having much shorter elytra. Addition of these two new species to the two previously known, S. sucini, from the eastern Baltic Sea coast, and S. bukejsi, from Kaliningrad Region, indicates that the genus Sucinoptinus was much more diverse and widespread in Late Eocene forests than former reports suggested.

A new genus and seven new species of the caddisfly families Polycentropodidae, Ecnomidae, Hydroptilidae, Phryganeidae and Leptoceridae (Archaeotinodes malickyi sp. nov., Archaeoneureclipsis martynovi sp. nov., Polycentropus grigorenkoi sp. nov., Oxyethira lurida sp. nov., Orthotrichia umbra sp. nov., Eotrichostegia retrograda gen. & sp. nov., Erotesis bessylenon sp. nov.) from the Rovno Amber (Upper Eocene, Ukraine) are described. A list of fossil Trichoptera known from the Rovno Amber is given.

A new caddisfly species Holocentropus tutkaktut sp. nov. (Polycentropodidae) is described from Priabonian Rovno amber (Upper Eocene, 33.9–37.8 million years old). With the new species, the family Polycentropodidae is represented in Rovno amber by 19 species, and the genus Holocentropus McLachlan, 1878, by nine species.

A new species of soldier beetles of the subfamily Cantharinae, Cacomorphocerus meridionalis sp. nov., is described from Upper Eocene Rovno amber. It is the second time that a Cacomorphocerus species with 11-segmented antennae has been discovered. The status of the tribe Cacomorphocerini is discussed.

Despite being among the most species-rich extant animal genera, Euconnus Thomson is rare in fossil record. Merely six species found in relatively young, Eocene and Oligocene ambers have been placed in this genus, which currently includes over 2,600 extant nominal species distributed worldwide. We describe †Euconnus nathani sp. n., the first extinct, unambiguously placed member of the broadly distributed, extant Palaearctic subgenus Cladoconnus Reitter, based on a unique male specimen in Upper Eocene Rovno amber, Ukraine. The male of the new species has monstrously modified antennae, in general structure showing close similarities to those of extant congeners, but the modification of antennomere 8 is so profound and bizarre that this one antennal segment alone is sufficient to identify adults of E. nathani.
