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).

AbstractSeven new species of Milichiella are described from Dominican amber: M. archaia n. sp., M. dolichosurstyla n. sp., M. dominicana n. sp., M. hennigi n. sp., M. margaretae n. sp., M. quadrisetosa n. sp., and M. theodori n. sp. These species represent the first record of the sub-family Milichiinae in amber and the first descriptions of the family in Dominican amber. The fossil species differ from extant species only in species-level details except M. archaia, which probably belongs to the stemline of Milichiella + Ulia.

Two New Species

Abstract. Two new fossil species of Baltocar Kuschel, 1992 and Pseudomesauletes Legalov, 2001 (Curculionoidea: Rhynchitidae) are described from Eocene Baltic amber. Baltocar sontagae sp. nov. is similar to B. groehni Riedel, 2012 but differs in the shorter rostrum, tarsomere 1 shorter than tarsomere 5 and 1.4× as long as tarsomere 2, longer elytra, and shorter body. Pseudomesauletes lobanovi sp. nov. is similar to P. culex (Scudder, 1893) and P. ibis (Wickham, 1912): the new species differs from P. culex in the larger eyes, longer pronotum, being 0.44× shorter than elytra, and slightly smaller body size; from P. ibis it differs in the smaller body size, rostrum shorter than elytra, and weakly convex pronotum. This is the first record of Pseudomesauletes from Baltic amber and the sixth species of Baltocar. Keys to species of the genus Baltocar and to the Eocene species of the genus Pseudomesauletes are given. Assumed trophic relationships of these fossil taxa are discussed (urn:lsid:zoobank.org:pub:260EBE6E-DA6C-4D6D-A1D2-2C258224622F).

Coleoptera Tenebrionidae

The fossil record of Tenebrionidae (excluding the Quartenary) is presented. In total, 122 fossil species, clearly belonging to the family, are known; some beetles were determined only to genus; 78 genera are listed in the fossil record, including 29 extinct genera. The great diversity of tenebrionids occurs in the Lower Cretaceous Lagerstätte of China (Yixian Formation), Middle Paleocene of France (Menat), Lower Eocene deposits of Germany (Geiseltal), Upper Eocene Baltic amber (Eastern Europe), Upper Eocene deposits of Florissant Formation (USA) and Miocene (Dominican amber). Tenebrionids of the following major lineages, including seven subfamilies, are currently known in the fossil record. These include the lagrioid branch (Lagriinae, Nilioninae), pimelioid branch (Pimeliinae), and tenebrioid branch (Alleculinae, Tenebrioninae, Diaperinae, Stenochiinae). The importance of the fossil record for evolutionary reconstructions and phylogenetic patterns is discussed. The oldest Jurassic and Early Cretaceous darkling beetles of the tenebrionoid branch consist of humid-adapted groups from the extant tribes Alleculini, Ctenopodiini (Alleculinae), and Alphitobiini (Tenebrioninae). Thus, paleontological evidence suggests that differentiation of the family started at least by the Middle Jurassic but does not indicate that xerophilic darkling beetles differentiated much earlier than mesophilic groups.

The record of the fossil representatives of the family Juliidae is updated. The new genus Candinia is proposed, in the subfamily Juliinae, for two fossil species somewhat intermediate between Julia and Berthelinia. The new species Candinia pliocaenica is recorded from the lower Pliocene shallow marine deposits near Siena (Tuscany, Italy). This is the first record of Sacoglossa in the Mediterranean Basin. Based on the very specialized life habits of the Juliidae, it is suggested that subtropical Caulerpa algal prairies inhabited the Mediterranean during the early Pliocene, likely becoming extinct in this basin because of the mid-Pliocene climatic deterioration.

The Myristicaceae is a member of the early diverging angiosperm order Magnoliales; however, the family is poorly represented by fossil collections. We describe Virola dominicana sp. nov. (Myristicaceae), the first record of fossilized Myristicaceae flowers, from mid-Tertiary (45–15 million years ago) Dominican amber. The description is based on 24 male flowers in 17 pieces of amber, thus providing some indication of intraspecific variation, including a two-tepaled flower. Diagnostic characters of the new species are the long-simple or few-branched trichomes on the perianth margins, the small pollen grains, and a short staminal column. These fossils also show co-occurring insects, some of which could be Virola pollinators. It is speculated that V. dominicana disappeared from Hispaniola during the Pliocene–Pleistocene cooling events leaving no native members of the Myristicaceae in this region today. Additionally, these fossils demonstrate that Myristicaceae was present in the Western Hemisphere during the mid-Tertiary.

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. A male representative of the extinct species Calomicrus eocenicus Bukejs et Bezděk, 2014 (Chrysomelidae: Galerucinae) is found and described for the first time from Eocene Baltic amber using X-ray microtomography. The aedeagus is well preserved within the body cavity of the specimen, and it is illustrated in detail. This fossil species exhibits distinct sexual dimorphism: the male has a smaller total body size, as well as a copula-adapted modification in abdominal ventrite 5 (apical margin deeply trilobed, with round medial fovea present); meanwhile the female is larger in body size and has a simple abdominal ventrite 5 (without fovea, non-incised and widely rounded apically). Similar sexually dimorphic characters are typical for extant members of the tribe Luperini, and this report is the first time that they are described in an Eocene species. The known sexually dimorphic characters present in Coleoptera within Eocene Baltic amber are briefly discussed.

Abstract. Rhopalosomatidae are a family of aculeate wasps that are ectoparasitoids of crickets as larvae and are predominantly distributed pantropically. The published fossil record of the family is scarce. Here, we report three new fossil rhopalosomatid wasp specimens from Dominican and Mexican amber. Rhopalosoma hispaniola Lohrmann sp. nov. is described and documented from Dominican amber by two separate inclusions – one of each sex. An additional fossil female Rhopalosoma is described and documented from Mexican amber but is not named due to the insufficient preservation of the fossil. The new fossils, which are morphologically intermediate between Townes' isopus and poeyi species groups, do not only represent the first fossil records of an extant genus of this peculiar family but also the first records of the family in Dominican and Mexican amber.
