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.

, Recorded from the Late Eocene Rovno amber (Ukraine) are above 300 families of Arthropoda. One hundred, seventy-four new species, 35 new genera and one new tribe have been described there in 45 families, including 42 species, 9 genera and one tribe of Hymenoptera. The first record of Scolebythidae is documented herein along with more detail information about Chrysididae which was only mentioned there before. Chrysidids are diverse and not very rare in the Rovno amber: four known inclusions represent at least three species in two genera. This makes a contrast with the Baltic amber: of 34 specimens known to Brues (1933), 30 represent only two species. Genera Pristapenesia BruesPalaeobethylus Brues and Palaeobethyloides Brues and species Palaeobethylus politus Brues and Pristapenesia primaeva Brues, previously known in Baltic amber only, are recorded in Rovno amber as well.

Abstract. A new weevil, Arostropsis perkovskyi Bukejs and Legalov, sp. nov. (urn:lsid:zoobank.org:act:408ECE71-B191-4381-AA39-C27A3A1DA082; Coleoptera: Curculionidae: Entiminae), is described from Late Eocene Rovno amber. The new species differs from Arostropsis groehni Yunakov et Kirejtshuk, 2011 from Baltic amber in the pronotum lacking a distinct lateral ridge, it has a shorter rostrum, antennomere 2 is subequal to antennomere 3, it has wider elytra with weaker convex humeral calli and the pronotum is wider than it is long. It is the first record of the tribe Naupactini in Rovno amber and the second finding of Arostropsis in Eocene ambers.

Limodromus emetikos sp. n. (Coleoptera: Carabidae) is described and illustrated from Baltic amber (Eocene). Based on its morphological features, the new species is considered a sister taxon of the extant Holarctic assimilis species group. Furthermore, the specimen described here could represent a case of stress-triggered regurgitation, which would represent the first fossil record of such a process in beetles.

Plesiomorphic Character

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.

A New Species

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 but exinct chelonine wasp species, Phanerotomella brevivena Kittel sp. nov. (Braconidae: Cheloninae) of the modern genus Phanerotomella is described from Baltic amber. This new species differs from all other extant Phanerotomella species by having the fore wing vein SR-1 only partially sclerotised. This is the first fossil record of the genus in amber.

Weak Similarity

Sympherobius irinae sp. nov. (Neuroptera: Hemerobiidae: Sympherobiinae) is described from the late Eocene Rovno amber, Ukraine. It differs from other species of the genus by small details in the forewing venation: (1) crossvein 3rp1-rp2 is not strongly shifted distally relative to neighboring crossveins in the third gradate series, and (2) the humeral veinlet has only two branches. All four late Eocene species form a distinctive species group, which is named here the completus species group, distinguished from other species of the genus by the presence of the crossvein 3rp2-rp3 in the forewing in distal position, connecting RP2 and RP3. The neuropteran assemblages of the Bembridge Marls and succinites (particularly Baltic and Rovno ambers) are briefly compared. The assemblages of some families are relatively similar, but there are obvious differences in others. It is impossible to draw conclusions about the age of Baltic or Rovno ambers based on this weak similarity.
