A new caddisfly of the fossil genus <Emphasis Type="Italic">Archaeotinodes</Emphasis> (Insecta: Trichoptera: Ecnomidae) from the Baltic amber

A new caddisfly species of the fossil genus Archaeotinodes, A. igneusaper sp. nov., is described from the Upper Eocene Baltic amber. The new species is close to A. pauper Ulmer, 1912 and A. lanceolata Ulmer, 1912 from the Baltic amber, differing from these in the structure of the male genitalia.     

First fossil record of Brachyptera (Plecoptera: Taeniopterygidae) in Eocene Baltic amber

The extant taeniopterygid genus Brachyptera Newport, 1848 is reported from the Eocene Baltic amber for the first time. A new species, Brachyptera dewalti n. sp. (Plecoptera: Taeniopterygidae), is described and illustrated based on a well-preserved female in the amber, distinguished by the presence of three well-developed ocelli, the dark color of antennae, maxillary palps, head, prothorax, and abdominal segments, the CuA vein of forewing with three branches, the nearly rhombus, dark brown postgenital plate, and the four-segmented cerci. It is the fourth taeniopterygid species known from the Baltic amber.     

A new fossil species of the extinct tribe Mimoplatycini Kazantsev, 2013 (Coleoptera Cantharidae)

A new fossil species from the Eocene Baltic amber of the extinct tribe Mimoplatycini Kazantsev, 2013 (Cantharidae Malthininae), is illustrated and described here. Mimoplatycis marchettii sp. nov. is characterized by a transverse but interrupted carina in the middle of pronotum. The tribe is known from Baltic and Rovno amber, and the pronotum with carinae similar to Lycidae could be interpreted as mimicry. The pronotal shape is here indicated as a diagnostic character of the species level.     

Have ladybird beetles and whiteflies co-existed for at least 40 Mya?

The beetle family Coccinellidae is rarely recorded from fossils. Most of the records come from the nineteenth and beginning of the twentieth century. A complete list of Coccinellidae records from Baltic amber is presented and discussed. Extensive literature research provided a surprising conclusion that not a single species of Coccinellidae has been formally described from Baltic amber till now. The first two species of ladybird beetles from Eocene Baltic amber are described and placed in the genus Serangium, namely S. twardowskii sp. nov. and S. gedanicum sp. nov. Their phylogenetic placement in the subfamily Microweiseinae is provided. A key to the fossil species of Serangium is given. Extant representatives of the genus are distributed mainly in tropical areas of Asia and Oceania, and are specialised predators of whiteflies. Current discovery shows that during the Middle Eocene, the genus Serangium was distributed wider in the Northern Hemisphere and the evolution of these ladybird beetles was probably influenced by the evolution of whiteflies which are also found in the Baltic amber.     

New species of Late Eocene dermestid beetles (Coleoptera, Dermestidae) from the Rovno and Baltic ambers

Fossil beetles of the family Dermestidae are reviewed. Three new species are described: Dermestes progenitor and Megatoma electra from the Baltic amber and Dermestes vetustus from the Rovno amber (Late Eocene).     

A new genus of myrmicine ant (Hymenoptera: Formicidae) from Eocene Baltic amber

Examination of fossil ant specimens from various private and institutional German collections of Baltic amber has revealed a new genus and species of Myrmicinae, described here as Thanacomyrmex hoffeinsorum gen. et sp. nov. The new worker morphotype shares some similarities with the coeval extinct genus Parameranoplus Wheeler, also from Baltic amber, and the extant genera Pristomyrmex Mayr and Acanthomyrmex Emery, suggesting placement of the new fossil in the Myrmecina genus-group within the tribe Crematogastrini. The new genus highlights the tremendous diversity of ants that evolved in the Palaeogene European forests and composed the first major radiation of crown-group ants.     

First fossil horsefly (Diptera: Tabanidae) in Miocene Mexican amber

The fossil record of the Tabanidae is sparse when compared with other families of Diptera. Even in amber they are rare, probably because of their size and specific flight behavior. Horseflies from amber are only known from Cretaceous age New Jersey amber as well as from the Tertiary age Baltic and Dominican amber, but are herein described for the first time, with Stenotabanus oleariorum sp. n., from Mexican amber. The new species is compared to the fossil horseflies of the same genus S. brodzinskyi Lane, Poinar and Fairchild 1988 and S. woodruffi Lane and Fairchild 1989 from Dominican amber.     

New species of the genus Glaesotropis (Insecta: Coleoptera: Anthribidae) from Rovno amber

A new species of the fungus weevil genus Glaesotropis is described from the Late Eocene Rovno amber. G. diadiasashai sp. nov. differs from G. weitschati and G. minor described from Baltic amber in having a longer rostrum and in the structure of its antennae, with the third and fourth antennomeres being longer than the first and second ones. Additionally, the new species differs from G. weitschati in being smaller, in having unswollen frons, and weakly and smoothly concave elytral margin near hind coxae. The new species also differs from G. minor in having an uninterrupted posterior transverse carina on the pronotum, elytra less convex longitudinally, and a slightly broadened rostrum at the attachment of antennae.     

Fossil Mesozoic and Cenozoic weevils (Coleoptera,Obrienioidea, Curculionoidea)

All known extinct species of Mesozoic and Cenozoic weevils are listed. Ten species of Obrienioidea and 895 Curculionoidea species are recognized, including 88 Nemonychidae, 43 Anthribidae, 44 Ithyceridae, 65 Scolytidae, 12 Belidae, 67 Brentidae, 508 Curcuionidae, 45 Rhynchitidae, six Attelabidae, and 16 Platypodidae.

(Baltic amber), and Electrauletes unicus Legalov, sp. nov. (Baltic amber) are newly described.     

New species of bark beetles from the Rovno amber (Insecta: Coleoptera: Scolytidae)

Two new species of bark beetles are described from the Late Eocene Rovno amber. Xylechinus mozolevskae sp. nov. (Hylesininae: Tomicini) is the first fossil representative of this genus, differing from recent species in having large triangular scales along the suture. Taphramites rovnoensis sp. nov. (Scolytinae: Dryocoetini) differs from the closest species, T. gnathotrichus from Baltic amber, in the presence of short thin hairs on the elytra.     

Thrips (Thysanoptera, Insecta) from the Rovno amber, Eocene of Ukraine

Seventy-six thrips were discovered in Rovno amber. Among these, 67 were identified to suborder, 52, to family, 45, to genus, and 41, to species level. In total, five species, six genera, five families, and two suborders are recorded. No undescribed taxa have been found so far. All the identified thrips, except those of the genus Phloeothrips, belong to fossil taxa, previously known only from the Baltic and Bitterfeld ambers. However, the composition of species in the Rovno amber is highly unusual due to domination of Praedendrothrips avus Priesner, 1924. This species, rare in the Baltic amber, constitutes 49% of all the Rovno records. Thus, the Rovno amber, in contrast to the Baltic and Bitterfeld ambers, is characterized by poor taxonomic diversity of thrips and presence of a clearly dominant species.     

New long-horned caddisflies in Eocene Baltic amber (Insecta,Trichoptera)

We describe two new extinct caddisflies, Electroadicella kuenowi sp. nov. and Triaenodes simoni sp. nov., embedded in Baltic amber. Both species belong to the tribe Triaenodini and enlarge the family Leptoceridae to a remarkable number of 18 extinct Eocene species from Baltic amber. The extinct Electroadicella and the extant Triaenodes are possibly closely related, by a distinct synapomorphy, a recurved process from the basal plate of the inferior appendages of the ninth abdominal segment in the male genitalia.     

Two new fossil genera and species of Cerocephalinae (Hymenoptera,Chalcidoidea, Pteromalidae), including the first record from the Eocene

Cerocephalinae (Chalcidoidea, Pteromalidae) is a small group of parasitoid wasps characterized by a number of derived diagnostic features. Their hosts are endophytic beetles. So far, 43 species of Cerocephalinae have been described, including one fossil species from the Miocene. In this study, we add two new genera and species from Baltic and Dominican amber to the fossil record. Tenuicornus dominicus gen. et sp. n. is the second genus described from Dominican amber, and Pteropilosa lailarabanorum gen. et sp. n., described from Baltic amber, represents the oldest record of the subfamily, pushing the minimum age of Cerocephalinae back to the Eocene. Diagnostic characters of both species are discussed in comparison with other Cerocephalinae. An updated key to extant and fossil Cerocephalinae is presented.     

A new genus and species of gall midges of the supertribe Heteropezidi (Diptera,Cecidomyiidae) found in Eocene amber from Sakhalin

A new genus and species of pedogenetic gall midge, Estoperpetua sakhalinica gen. et sp. nov., of the tribe Heteropezini (subfamily Lasiopterinae) is described. Gall midges have not been recorded in Eocene amber of Sakhalin. A female with 4-segmented tarsi, large transparent triangular sensoria on flagellomeres, short wings and legs, and long 2 + 9-segmented antennae is described. Heteropezidi shows the greatest generic and species diversity in the Late Eocene Rovno amber. Representatives of this supertribe were also found in the Late Eocene Baltic amber, Early Eocene Oise amber, Miocene amber from Mexico and Dominican Republic, and African copal. Heteropezidi from different amber faunas are reviewed.

(Entiminae: Cneorhinini alaeophelypera) from Baltic amber are described. Isotheinae Scudder 1893, n. syn. is synonymised to the tribe Rhynchitini Gistel, 1848. Trichapiina Alonso-Zarazaga 1990, n. syn. is synonymised to the subtribe Toxorhynchina Scudder 1893. Phialodes durus (Heer 1865), n. placem. and n. comb. is transferred from the genus Attelabus Linnaeus, 1758 to the genus Phialodes Roelofs, 1874.     

Beiträge zur kenntnis fossiler trauermücken aus Sächsischem Bernstein. teil II. Drei neue sciariden aus tertiär-Harzen des bitterfelder braunkohlereviers (insecta,diptera, sciaridae)

Examination of 278 pieces of fossil resins from the lower Miocene Saxonian amber (opencast mining Goitsche/Bitterfeld/Germany) yielded to a total of 60 Sciarids in 29 pieces of amber. They belong to 9 species from 3 genera. The speciesEpidapus Primarius, Trichosia (Palaeotrichosia) voelsgeni andTrichosia (Palaeotrichosia) kedingi are new. The other species are known also from Baltic amber.     

A new species of tumbling flower beetles of the genus Mordellaria (Insecta: Coleoptera: Mordellidae) from the Baltic amber

The beetle Mordellaria friedrichi sp. nov. is described from the Baltic amber. The new species differs from extant species of the genus in the shape of the eyes and antennae and in the ratios of the length of the pygidium and length of the elytron, pronotum, and anal sternite.     

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.
