No species in common with the fauna from the Baltic amber are recorded.     

Seven new species of caddisflies (Insecta: Trichoptera) from the Rovno amber (Eocene of Ukraine)

Seven new caddisfly species of the families Polycentropodidae, Psychomyiidae, and Lepidostomatidae are described from the Late Eocene Rovno amber: Holocentropus kobodok sp. nov., H. zhiltsovae sp. nov., Plectrocnemia nastigermania sp. nov., P. ucrainica sp. nov., Nyctiophylax terreusbos sp. nov., Lype essentia sp. nov., and Lepidostoma quasitypica sp. nov.     

A new Planthopper (Insecta: Hemiptera: Nogodinidae) from Chiapas amber, middle Miocene of Mexico

A new species of Planthopper, Nogodina chiapaneca sp. nov. from the Mexican Chiapas amber (southeast Mexico) is described. The new species belongs to Nogodinidae: Nogodinini: Nogodinina. This is the second nogodinid species described from Mexican amber. Both species belong to Nogodinina, a taxon with a Neotropical distribution. The only recent species of Nogodina, N. reticulata, ranges from Honduras to Brazil and is unknown from Mexico yet.     

Ants of the Genus <Emphasis Type="Italic">Fallomyrma</Emphasis> Dlussky et Radchenko (Hymenoptera,Formicidae, Myrmicinae) from Late Eocene European Ambers

The extinct monotypic ant genus Fallomyrma was described by Dlussky and Radchenko in 2006 based on workers from Late Eocene Rovno (Ukraine), Scandinavian (Denmark), and Bitterfeld (Germany) ambers. Three new Fallomyrma species from the Rovno amber are here described based on workers: F. anodonta sp. nov., F. marginata sp. nov., and F. robusta sp. nov. A key to all known species of this genus is compiled. The quantity ratios (of the numbers of species and specimens) of Fallomyrma and other amber Myrmicinae genera are considered. The opinion of the autochthonous origin of the Rovno amber is confirmed.

(Belidae), Eocenorhynchites vossi gen. et sp. nov. (Rhynchitidae), and Archaeosciaphilus marshalli gen. et sp. nov. (Curculionidae), are described.     

First gall midges (Diptera,Cecidomyioidea) from Late Cretaceous amber of the Taimyr Peninsula

Gall midges from Santonian amber of Yantardakh (Taimyr Peninsula) are investigated for the first time. Eight new genera and eight new species belonging to five tribes of the subfamily Micromyinae (Lestremiidae) are described. These are Caputmunda yantardakhica gen. et sp. nov. (Catochini), Cretoperomyia taimyrica gen. et sp. nov.

(Micromyini), and Cretomycophila ekaterinae gen. et sp. nov., and Corporesana khatanga gen. et sp. nov. (Aprionini). A representative of Porricondylinae (Cecidomyiidae, Porricondylinae, Holoneurini) is recorded. The diagnoses based on morphometric parameters of tribes and previously established genera are emended. The species composition of gall midges from three Cretaceous amber faunas of different ages are analyzed.     

New species of sap beetles (Coleoptera: Nitidulidae: Nitidulini) from the Baltic and Bitterfeld ambers

A new genus, Microsoronia, gen. nov., and new species of this genus, M. hoffeinsorum, sp. nov. from the Bitterfeld amber and M. kerneggeri sp. nov., M. nigerrima sp. nov., and M. interfax, sp. nov. from the Baltic amber, are described. The earliest known member of the genus Phenolia, P. (Lasiodites) angustitibialis, sp. nov., is described from the Baltic amber. The systematic position of these two genera, their possible evolution, as well as the possible ecology and bionomics of their members are discussed. It is shown that “Phenolia” incapax Scudder, 1890 should be included in the family Peltidae, rather than Nitidulidae.     

A new species of derelomine weevils (Coleoptera,Curculionidae, Curculioninae: Acalyptini) from the Rovno amber

Protoceletes hirtus sp. nov. (Curculionidae: Curulioninae: Acalyptini) from the Late Eocene Rovno amber is described. This is the second fossil of the genus. The new species is close to P. wolfschwenningerae Rheinheimer, 2007 from Baltic amber and differs it in the separated coxae, asymmetrically convex eyes, longer and clearly semierect hairs on the surface, and the longer body.     

Palaeobiology of tanaidaceans (Crustacea: Peracarida) from Cretaceous ambers: extending the scarce fossil record of a diverse peracarid group

Diverse assemblages of tanaidacean peracarid crustaceans from western Tethyan continental deposits suggest that the group was relatively common in or around ancient resin‐producing forests. Here we report the results of an examination of 13 tanaidacean specimens from three Cretaceous (Albian to Turonian) French amber deposits. Two new species of the fossil family Alavatanaidae are placed in the previously described Early Cretaceous genus Eurotanais: Eurotanais pyrenaensis sp. nov. from Cenomanian Pyrenean amber (Fourtou, Aude) and Eurotanais seilacheri sp. nov. from Turonian Vendean amber (La Garnache, Vendée). The remaining specimens are placed in three newly erected genera and species (but family incertae sedis): Arcantitanais turpis gen. et sp. nov. from Albian–Cenomanian Charentese amber (Archingeay, Charente‐Maritime), and Tytthotanais tenvis gen. et sp. nov. and Armadillopsis rara gen. et sp. nov. from Pyrenean amber. These are the first formally described fossils that might be related to the paratanaoidean families Nototanaidae and Paratanaidae, sharing with these some putatively derived features and providing possible evidence for the antiquity and morphological stability of these families and the suborder Tanaidomorpha. The distinctive features and character combinations of these fossil taxa are discussed in connection with possible relationships to the living lineages of tanaidaceans. Propagation phase‐contrast X‐ray synchrotron microtomography was used to obtain high‐quality 3D images for some fossils. A discussion is provided on the putative palaeobiology of tanaidaceans and the French resiniferous forest ecosystem. The discovery of these new tanaidaceans extends the palaeogeographical distribution and stratigraphical range of the family Alavatanaidae and sheds new light on the palaeoecology and diversity of tanaidaceans in pre‐angiospermous woodlands.     

Archaeotinodes ivanovi sp. nov., a new fossil species of Ecnomidae (Insecta: Trichoptera) from the Baltic amber

Archaeotinodes ivanovi sp. nov., a new species of the fossil genus Archaeotinodes, is described from the Eocene Baltic amber. The new species is generally similar to A. pauper Ulmer, 1912 and A. igneusaper Melnitsky, 2009 from the Baltic amber and to A. reveraverus Melnitsky et Ivanov, 2010 from the Rovno amber.     

New gall midge taxa of the subfamilies porricondylinae and lasiopterinae (Diptera,Cecidomyiidae) from the Rovno amber

Five new gall midge taxa of the subfamilies Porricondylinae and Lasiopterinae are described from the Late Eocene Rovno amber: Adsumyia integra gen. et sp. nov. (Dicerurini), Gratomyia inexigentis gen. et sp. nov. (Holoneurini), Winnertzia recusata sp. nov. (Winnertziini), Kovaleviola injusta gen. et sp. nov., and Spungisiola insuperabilis gen. et sp. nov. (Brachineurini).     

Two Flat-Backed Polydesmidan Millipedes from the Miocene Chiapas-Amber Lagerst?tte,Mexico

Two species of fossil polydesmidan millipedes (Diplopoda: Polydesmida) embedded in amber are described from Miocene strata near Simojovel, in the Chiapas Highlands, Mexico. Maatidesmus paachtun gen. et sp. nov., placed into Chelodesmidae Cook, 1895, and Anbarrhacus adamantis gen. et sp. nov., assigned in the family Platyrhacidae Pocock, 1895. Morphological data from fossil specimens have been recovered using 3D X-ray micro-computed tomography and regular to infrared-reflected microscopy. Both fossil species are recognizable as new primarily but not exclusively, by collum margin modification and remarkable paranotal and metatergite dorsal sculpture.     

A new species of Craspedisia (Araneae: Theridiidae) in Miocene Dominican amber, imaged using X-ray computed tomography

A new spider species of the extant genus Craspedisia Simon (Araneae: Theridiidae) is described from a fossil in Miocene amber from the Dominican Republic. X-ray computed tomography (CT) was used to reveal important features that were impossible to view using traditional microscopy, because of the position in which the spider is preserved. Craspedisia yapchoontecki sp. nov. is the first described fossil species from this genus and has its closest relative among the extant Hispaniolan fauna.     

New genera and species of Scelionidae (Insecta: Proctotrupoidea) from Rovno amber

Two new genera and three new species of parasitic wasps from the family Scelionidae are described from the Late Eocene Rovno amber: Pseudotelea gracilis Kononova, gen. et sp. nov. (subfamily Scelioninae), Pseudidris striatus Kononova, gen. et sp. nov., and Ceratobaeoides cornutus Kononova, sp. nov. (subfamily Baeinae). The new taxa are compared with representatives of the Recent fauna.     

Species of two paleoendemic sap beetle genera of the Tribe Nitidulini (Nitidulidae: Coleoptera) from the Baltic and Dominican amber

Omositoidea gigantea Schaufuss, 1892 is redescribed; O. pubescens sp. nov. from the Baltic amber, Palaeometopia dominicana gen. et sp. nov. and P. colorata gen. et sp. nov. from the Dominican amber are described. The taxonomic position of the two genera and their probable bionomy are discussed.     

New genus of fossil apoid wasps (Hymenoptera,Apoidea) from the Cretaceous amber of Myanmar

The new genus 2Burmasphex is proposed for two fossil species, 2Burmasphex sulcatus sp. nov. and 2Burmasphex pilosus sp. nov., described from Myanmar Cretaceous amber. It exhibits many plesiomorphic features in relation to the extant Apoidea and is here provisionally allocated in the extinct family 2Angarosphecidae.     

New species of sap beetles (Coleoptera: Nitidulidae: Epuraeinae,Cybocephalinae) from the Baltic amber

A new genus, Baltoraea gen. nov., two new species of this genus, B. insignis sp. nov. and B. simillima sp. nov., and three other new species, Cybocephalus (Cybocephalus) balticus sp. nov., C. (C.) electricus sp. nov. and C. (C.) kerneggeri sp. nov. are described from the Late Eocene Baltic amber. The systematic position of the genus Baltoraea and presumable bionomics of the new sap beetles are discussed.
