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.

A New Species

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.

Abstract The beetle Ceutorhynchus is used as a proxy for Eocene core Brassicaceae. The age of Brassicaceae has been strongly debated because their fossil record is scanty. There are four species of Ceutorhynchus inaffectatus species-group known in the Priabonian: Ceutorhynchus zerovae new species in Rovno amber and three in Baltic amber. There are numerous extant members of the group, all of which feed on core Brassicaceae. Together with differentiation of Brassicaceae-feeding Pierinae (Lepidoptera) in the Priabonian, the strong presence of Ceutorhynchus indicates at least an early Priabonian age of core Brassicaceae. The oldest fossil Brassicaceae is not known in the late Eocene of Europe, but was recorded in Montana, dated in some studies as late Oligocene, but recently as Priabonian (34 Ma). Ceutorhynchus zerovae n. sp. is very close to C. electrinus from Baltic amber. UUID: http://zoobank.org/7f10761f-463d-44c5-9eef-bb4697bfb116.

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.
