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.

Abstract. A new pear-shaped weevil, Toxorhynchus europeoeocenicus Bukejs et Legalov, sp. nov. (Coleoptera: Brentidae: Apioninae), is described from upper Eocene Rovno amber using X-ray microcomputed tomography (µCT). The new fossil species differs from the extinct Toxorhynchus robustus Poinar et Legalov, 2015 (Dominican amber, lower Miocene) in the larger body size, narrower elytral striae, and wider pronotum. It is the first record of the family Brentidae in Rovno amber and the first record of the genus Toxorhynchus in the eastern hemisphere (urn:lsid:zoobank.org:pub:8FB7B299-EE75-4556-B4EA-203A3CBED84C).

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.

AbstractFirst record of the genus Helius—long-rostrum cranefly from Maestrazgo Basin (eastern Spain, Iberian Penisula) is documented. Two new fossil species of the genus Helius are described from Cretaceous Spanish amber and compared with other species of the genus known from fossil record with particular references to these known from Cretaceous period. Helius turolensis sp. nov. is described from San Just amber (Lower Cretaceous, upper Albian) Maestrazgo Basin, eastern Spain, and Helius hispanicus sp. nov. is described from Álava amber (Lower Cretaceous, upper Albian), Basque-Cantabrian Basin, northern Spain. The specific body morphology of representatives of the genus Helius preserved in Spanish amber was discussed in relation to the environmental conditions of the Maestrazgo Basin and Basque-Cantabrian Basin in Cretaceous.

Paleocene spatangoids are unknown from the Antilles, apart from evidence from trace fossils. The peak of spatangoid diversity was the Eocene. Jamaican Oligo-Miocene spatangoids have a relatively low diversity compared with that of the Antillean region. Plio-Pleistocene spatangoids are poorly known from the Antilles (four genera), in contrast to the Oligo-Miocene (16 genera) and Holocene (17 genera). The depauperate Paleocene and Plio-Pleistocene spatangoid faunas are probably in part artifacts of incomplete sampling, facies-related absences, outcrop area effects and the relative brevity of these stratigraphic intervals.To the large echinoid fauna of the Swanswick Formation (Middle-Upper Eocene) of Jamaica is added the schizasterid Aguayoaster schickleri new species. This is the first record of this genus outside Cuba; it is distinctly more elongate than all other known specimens of this genus. The schizasterid Caribbaster loveni (Cotteau, 1875) is recorded from the Swanswick Formation for the first time, the youngest occurrence of this genus in Jamaica. The coeval Claremont Formation has not previously yielded spatangoid echinoids; the brissid Eupatagus cf. antillarum (Cotteau) from a new locality is the first spatangoid known from a lagoonal unit of the White Limestone Group.

AbstractThe problematic calcified cnidarian Cambroctoconus is described from the Henson Gletscher Formation (Cambrian Series 2, Stage 4–Series 3, Stage 5) of North Greenland, representing the first record from Laurentia of a genus otherwise recently described from China, Kyrgyzstan, and Korea. Internal molds produced by penetrative phosphatization mirror the pervasive pore system of the calice walls and septa. The pore system is compared to the network of gastrodermal solenia that distributes nutrients between polyps and surrounding stolon tissues in present day octocorals. In conjunction with the octagonal form of the individual coralla and eight-fold symmetry of septa, the pore system promotes assignment of Cambroctoconus to the Octocorallia, a basal clade in cnidarian phylogeny. Octocorals (‘soft corals’) are diverse in present day seas, but have a poor fossil record despite the general development of distinctive calcareous spicules. New taxa: Order Cambroctoconida new; Cambroctoconus koori new species.

ABSTRACTA new flower preserved in amber in sediments of Simojovel de Allende, México, is identified as an extinct member of Staphyleaceae, a family of angiosperms consisting of only three genera (Staphylea, Turpinia and Euscaphis), which has a large and abundant fossil record and is today distributed over the Northern Hemisphere. Staphylea ochoterenae sp. nov. is the first record of a flower for this group, which is small, pedicelled, pentamer, bisexual, with sepals and petals with similar size, dorsifixed anthers and superior ovary. Furthermore, the presence of stamens with pubescent filaments allows close comparison with extant flowers of Staphylea bulmada and S. forresti, species currently growing in Asia. However, their different number of style (one vs. three) and the apparent lack of a floral disc distinguish them from S. ochoterenae. The presence of Staphyleaceae in southern Mexico ca. 23 to 15My ago is evidence of the long history of integration of vegetation in low-latitude North America, in which some lineages, such as Staphylea, could move southwards from high latitudes of the Northern Hemisphere, as part of the Boreotropical Flora. In Mexico it grew in association with tropical elements, as suggested by the fossil record of the area.

Parasinalda sukachevae sp. nov. (Hemiptera: Heteroptera: Tingidae: Tinginae: Phatnomini) is described based on one specimen from Eocene amber of the Rovno region (Ukraine). Similarities and differences to closely related species Parasinalda baltica (Drake, 1950), P. froeschneri (Golub & Popov, 1998), and P. groehni Heiss & Golub, 2013 are discussed, and a key to the four known species of the genus is provided.
