Succinoraphidia radioni sp. nov. (Raphidiidae) is described from the late Eocene Rovno amber, Ukraine. The genus also includes two species from contemporaneous Baltic amber, i.e., S. exhibens Aspöck & Aspöck, 2004 and S. baltica (Carpenter, 1957), comb. nov. The venation of Succinoraphidia is analysed. It possesses several plesiomorphic character states at the family level, and the monotypic subfamily Succinoraphidinae represents a basal group within the family or possibly even a potential stem group of Raphidiidae. All diagnostic character states of Succinoraphidia (except the structure of the pterostigma) are found in a few Cretaceous species of the paraphyletic Mesoraphidiidae, but some of these are not found in the extant Raphidiidae.

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 species of the fossil ant genus Drymomyrmex Wheeler, 1915, D. rasnitsyni sp. nov., is described from the late Eocene Rovno amber (Ukraine). This is the first find of a worker of this genus and the first record of Drymomyrmex in the Rovno amber. Based on the analysis of the morphological features of gynes and worker it is proposed to attribute Drymomyrmex to the tribe Plagiolepidini Forel, 1886.

A new species of the late Mesozoic–Cenozoic family Ringiculidae (Ringicula (Ringicula) cockburnensis n. sp.) is described from basal glauconitic beds of late Eocene age of Cockburn Island, Antarctica, and is the first reported occurrence of the family Ringiculidae from the continent of Antarctica. Ringicula (R.) cockburnensis n. sp. most closely resembles R. castigata from the middle Oligocene Duntroonian Stage of New Zealand and provides further support for the strong provinciality (Weddellian Province) that existed along the southern margin of the Pacific during the Late Cretaceous and early Tertiary.

A new species of malachite beetles, Protomauroania mikhailovi Tshernyshev & Perkovsky, sp. n. is described from late Eocene Rovno amber. The new beetle is the second species of the Eocene fossil genus Protomauroania Tshernyshev, 2021 that was first recorded in Rovno amber and shows fauna similarity of dasytids in Baltic and Rovno amber. The new species is typical owing to the following characters: antennae with 5-segmented wide club, surface covered with dark-brown long semi-erect thin setae, and the ultimate ventrite (apical sternite) simple, narrow, not depressed. Digital high resolution pictures of the beetle are provided.

A species of the genus Isoperla Banks, 1906, I. oncocauda Huo & Du, sp. nov. is described as new to science and is the first record for the family Perlodidae from the Tianmu Mountain Nature Reserve, Zhejiang Province of eastern coastal China. Both sexes of the new species are characterized by tergum 10 with a developed process. The partially extruded aedeagus of the male is membranous without conspicuous larger sclerites and with the ventral surface covered with dense scale-like and nail-shaped spines.

The genus Smacigastes Ivanenko & Defaye, 2004 (Harpacticoida, Copepoda) is the most primitive genus in the family Tegastidae Sars, 1904, occurring in deep-sea chemosynthetic environments, such as hydrothermal vents, cold seeps, whale falls and wood falls. Our exploration of the Onnuri Vent Field, the sixth active hydrothermal vent system in the Central Indian Ridge, resulted in the discovery of a new species in the genus Smacigastes. A detailed morphological analysis of S. pumilasp. nov. reveals that it most resembles S. barti Gollner, Ivanenko & Martínez Arbizu, 2008, described from a hydrothermal vent in the East Pacific Ridge; the new species can be distinguished from the existing species by the 8-segmented female antennule, the absence of an abexopodal seta on the antennary basis, the mandibular exopod represented by a single seta and the exopod of the first leg with five setae. This is the first record of Smacigastes in the Indian Ocean. A dichotomous key to species of the genus Smacigastes worldwide is provided.

A new species of Dynomene from the Priabonian (Upper Eocene) of the central Pyrenees in Aragón (Spain) is described as the first record of the genus from the Iberian Peninsula. The new species reveals close similarities to other dromioid species described from the Priabonian of Hungary. The panopeid Eoacantholobulus oscensis Ossó & Domínguez, 2017, from the same locality, is reviewed and transferred to the genus Sculptoplax, after comparisons with specimens of Sculptoplax rigida Müller & Collins, 1991 from the Priabonian of Italy. The present note again provides evi- dence of the close relationship between the Late Eocene decapod crustacean faunas of the western-most Tethys and the Pyrenean basins.
