A new species of the genus <Emphasis Type="Italic">Anthonomus</Emphasis> Germar (Curculionidae) in Mexican amber

A new species, Anthonomus dilatofemurus Poinar et Legalov, sp. nov., from Mexican amber is described and illustrated. The new species is close to A. cruraluma Poinar et Legalov and differs from it in the wider elytra with narrow striae and strongly swollen pro- and metafemora. It differs from A. browni Poinar et Legalov in the wide and short elytra, shorter and thicker weakly curved rostrum, and strongly swollen metafemur. It is distinguished from A. camoiranensis Clark by the metatitibia with uncus and from A. sulcatus Kirsch by the protibia with uncus, metatibia with ventral fringe of medium scales, narrower elongate pronotum, weakly convex elytra and weakly curved rostrum.     

Miospores from the Frasnian-Famennian Boundary deposits in Eastern Europe (the Pripyat Depression, Belarus and the Timan-Pechora Province, Russia) and comparison with Western Europe (Northern France)

A zonal subdivision of the Frasnian-Famennian transitional deposits in the Pripyat Depression and Timan-Pechora Province, based on a detailed palynological study, has been completed. The data obtained on miospores and conodonts from the Timan-Pechora Province enable a correlation to be made with the Standard Conodont Zonation. The lateral extent of the palynozones in Eastern Europe and the correlation with Western Europe are discussed. The following previously published new combinations are validated: Auroraspora speciosa (Naumova) Obukhovskaya, comb. nov., Corbulispora viminea (Nekriata) Obukhovskaya and Nekriata, comb. nov., Cristatisporites imperpetuus (Sennova) Obukhovskaya, comb. nov., Cymbosporites acanthaceus (Kedo) Obukhovskaya, comb. nov., Grandispora subsuta (Nazarenko) Obukhovskaya, comb. nov., and Verrucosisporites evlanensis (Naumova) Obukhovskaya, comb. nov.     

Sayrevilleinae Legalov,a newly recognised subfamily of fossil weevils (Coleoptera,Curculionoidea, Attelabidae) and the use of synchrotron microtomography to examine inclusions in amber

Two genera of extinct weevils, Sayrevilleus Gratshev & Zherikhin from Cretaceous New Jersey amber and Baltocar Kuschel from Eocene Baltic amber, are recognized as close relatives based on similarities revealed by the use of synchrotron tomography and the availability of new amber inclusions. The subfamily Sayrevilleinae Legalov stat. nov. is characterized by possessing mandibles with an external cutting edge and an inner blunt edge. The subfamily is placed in the family Attelabidae (s.l.), although some characters also suggest a possible relationship with the ‘higher weevils’ comprising Caridae, Brentidae, and Curculionidae. Sayrevilleus is transferred from the tribe Auletini of Rhynchitinae to Sayrevilleinae, and Sayrevilleus grimaldii Gratshev & Zherikhin is redescribed. Baltocar Kuschel is transferred from Caridae to Sayrevilleinae and revised, its type species, Baltocar succinicus (Voss), is redescribed and three new species, Baltocar groehni Riedel sp. nov. , Baltocar hoffeinsorum Riedel sp. nov. , and Baltocar subnudus Riedel sp. nov. are described based on eight well‐preserved inclusions. The genera Orapauletes Legalov and Zherichiniletes Legalov previously assigned to Sayrevilleini are regarded as Curculionoidea incertae sedis. The Sayrevilleinae were distributed over areas of North America and Europe at least since the Late Cretaceous (c. 90 Mya) and were probably relatively diverse until the Eocene (c. 44 Mya). It is speculated that they became extinct through competition with Curculionidae, which used a similar oviposition strategy. © 2012 The Linnean Society of London, Zoological Journal of the Linnean Society, 2012, 165 , 773–794.

New species of the subfamily Cossoninae (Coleoptera: Curculionidae) in Dominican amber

The following new genus and seven new species of Cossonine weevils (Curculionidae: Cossoninae) are described from Dominican amber: Acamptus exilipes Poinar and Legalov, n. sp. (similar to A. rigidus), Caulophilus camptus Poinar and Legalov, n. sp. (similar to C. bennetti), Caulophilus elongatus Poinar and Legalov, n. sp.

New tribe,genus, and species of paedogenetic gall midges (Diptera,Lestremiidae: Krassiloviolini trib. nov.) from the Late Cretaceous Taimyr amber

Paedogenetic fossil midges of the family Lestremiidae are revealed for the first time. Only eight species of eight gall midge genera belonging to five tribes of the subfamily Micromyinae (Lestremiidae) and two species of two genera of Porricondylinae (Cecidomyiidae: Porricondylinae sp., Holoneurini sp.) have previously been described from the Santonian Taimyr amber of Yantardakh. The new tribe Krassiloviolini trib. nov. differs from other tribes of Lestremiidae in the strong reduction of veins and flagellomeres, slightly differing in length first and second tarsomeres of the middle and hind tarsi, 3-segmented apical plates of the ovipositor, and the presence of paedogenesis. A new genus and species, Krassiloviola geniusloci gen. et sp. nov., is described based on a female that is characterized by the first front tarsomere 1.3 times as long as the second, short 2+7-segmented antennae, presence of stem and large narrow sensoria on flagellomeres, wide wings with strongly reduced vein R5, slightly forked Cu, and absence of fragment C behind the fusion with R5. The presence of two very large specific eggs is evidence of the existence of paedogenesis in the Late Cretaceous. Previously, fossil paedogenetic eggs have only been known in Miastor vlaskini (Fedotova et Perkovsky) described from the Late Eocene Rovno amber.     

A Neontologist’s review of two recently published articles on inclusions of Lestremiinae (Diptera: Cecidomyiidae) in Rovno amber

As a result, the following gall midges species are considered Lestremiinae incertae sedis: + Aprionus admirandus Fed., + Conarete laesus Fed., + Heterogenella sparsa Fed., + Micromyia convoluta Fed., + Peromyia autonoma Fed., + Peromyia miranda Fed., + Peromyia sukachevae Fed., + Peromyia zherikhini Fed. (all in Perkovsky and Fedotova, 2004), + Campylomyza falciformis Fed., + Campylomyza superposita Fed., + Neurolyga declinata Fed., + Strobliella appropinquata Fed., and + Strobliella capitata Fed. (all in Fedotova and Perkovsky, 2004).     

The first fossil record of mites of the family Pyemotidae (Acari: Heterostigmata), with description of a new species of the genus <Emphasis Type="Italic">Pyemotes</Emphasis> from Rovno amber

The first fossil mite of the family Pyemotidae (Acari: Heterostigmata) is recorded. Pyemotes primus sp. nov. is described from the Late Eocene of the Rovno amber from a syninclusion with the bark beetles Taphramites rovnoensis Petrov et Perkovsky, 2008. In the presence of well developed longitudinal striation on hysterosomal tergites, the new species is similar to species from scolyti group, which is characterized by parasitoidism on immature stages of bark beetles and phoresy on adult stages. P. primus differs from the closely related species P. dryas (Vitzthum, 1923), P. parviscolyti Cross et Moser, 1971, P. johnmoseri Khaustov, 2004, and P. mandelshtami Khaustov, 1998 in the subequal setae h ₁ and h ₂.     

Interphase cytogenetics in estimation of genomic mutations in somatic cells

The review considers the current state, possibilities, and perspectives of using interphase cytogenetics in the estimation of genomic mutations in human and animal somatic cells for aims of genetic toxicology and genetic instability analysis. Possible mechanisms underlying action of mutagens causing numeric chromosome aberrations are discussed.Translated from Genetika, Vol. 41, No. 1, 2005, pp. 5–16.Original Russian Text Copyright © 2005 by Timoshevsky, Nazarenko.     

New tribes of the superfamily Curculionoidea (Coleoptera) in Burmese amber

Two new tribes in the Curculionoidea are described as the Anchineini Poinar and Legalov, n. trib. (Ithyceridae: Carinae) and Paleocryptorhynchini Poinar and Legalov, n. trib. (Curculionidae: Erirhininae). The genus Anchineus Poinar and Brown, 2009, n. placem. is transferred from the subfamily Curculioninae of the family Curculionidae to the subfamily Carinae of the family Ithyceridae. The genus Paleocryptorhynchus Poinar, 2009, n. placem. is transferred from the subfamily Cryptorhynchinae to the subfamily Erirhininae. The placement of the genus Mesophyletis Poinar, 2006 in the family Ithyceridae was confirmed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:0C0039DD-7BC6-4A54-9282-F43C5606D68B     

A new species of the genus Disogmus Förster (Hymenoptera, Proctotrupoidea, Proctotrupidae) from the Eocene Rovno amber

Disogmus rasnitsyni Kolyada & Perkovsky, sp. n. is described from a fossil inclusion of Late Eocene amber (Ukraine). The new species is most similar to Disogmus basalis (Thomson, 1857), in particular, in the shape of the tyloids and the general shortening of the segments of antennae, but distinctly differs from it and the other species of the genus by having tyloids on flagellar segments 2-4 compared to 3-6 and 4-7 in other species.     

Mutliaberrant cell formation caused by exposure to internal densely-ionizing irradiation

The origin of multiaberrant cells (MACs) was studied by comparing the structure and intensity of chromosome damage in peripheral blood lymphocytes of two groups of people: workers of Siberian Chemical Plant differing in the content of plutonium-239 in their bodies, and inhabitants of a non-polluted settlement (control group). Plutonium-239 is known to be a long-lived densely-ionizing source of -radiation with high linear energy delivery; therefore, it has a stronger effect on cell hereditary structures than -rays. In persons with the content of plutonium-239 higher than 13 nCu, the frequency of MAC was 0.105% which at least tenfold exceeds the spontaneous level. The chromosome-type aberrations that are usually induced by ionizing radiation predominated in MACs. Our results suggest that MAC formation may be caused by internal body irradiation with the incorporated sources of densely-ionizing radiation.Translated from Genetika, Vol. 40, No. 12, 2004, pp. 1709–1713.Original Russian Text Copyright © 2004 by Popova, L.

Third contribution on Rovno amber silken fungus beetles: a new Eocene species of Cryptophagus (Coleoptera, Clavicornia, Cryptophagidae)

Cryptophagus alexagrestis Lyubarsky & Perkovsky, sp. n. is described based on a fossil inclusion in Late Eocene Rovno amber (Ukraine). The new species is similar to the extant Cryptophagus skalitzkyi Reitter and Cryptophagus dilutus Reitter, differing from the latter by having a very transverse, short and dilated 10th antennal segment, and from the former by the very elongate segments of the flagellum.
