    A New Mantispid-Like Species of Rhachiberothinae (Neuroptera: Berothidae) from Baltic Amber, with a Critical Review of the Fossil Record of the Subfamily

    ACTA GEOLOGICA SINICA (ENGLISH EDITION), Issue 4 2010
    Vladiir N. MAKARKIN
    Abstract: Whalfera wiszniewskii sp. nov. is described from the Late Eocene Baltic amber. The genus Whalfera is considered as the only fossil genus confidently assigned to the Rhachiberothinae. Others previously placed in this subfamily belong to Paraberothinae (except perhaps for Oisea). The Late Eocene/present Rhachiberothinae and the Cretaceous Paraberothinae are considered to be the subfamilies of Berothidae. [source]


    Microelectrona cladara gen. et sp. nov.: A New Protodikraneurini from the Eocene Baltic Amber (Hemiptera: Cicadomorpha: Cicadellidae: Typhlocybinae)

    ACTA GEOLOGICA SINICA (ENGLISH EDITION), Issue 4 2010
    Jacek SZWEDO
    Abstract: A new genus Microelectrona gen. nov. and species Microelectrona cladara sp. nov. of the extinct tribe Protodikraneurini of the leafhoppers (Cicadellidae: Typhlocybinae) from the Eocene Baltic amber is described. The piece of amber containing leafhopper inclusion is broken, unveiling some of the morphological structures, and enabling their studies using scanning electron microscopy. [source]


    A New Species Group in the Genus Tanytarsus van der Wulp (Diptera: Chironomidae) Based on a Fossil Record from Baltic Amber

    ACTA GEOLOGICA SINICA (ENGLISH EDITION), Issue 4 2010
    Wojciech GI
    Abstract: A new fossil chlronomid, Tanytarsus serafini, found in Baltic amber is described and illustrated based on adult males. The new species and similar extant species of the genus Tanytarsus van der Wulp are compared. Due to several distinct characters of wing, legs and hypopygium, a new species group for Tanytarsus serafini is proposed, and its diagnostic features are evaluated. [source]


    A New Species of Dactylolabis (Eobothrophorus) from Baltic Amber (Diptera: Limoniidae)

    ACTA GEOLOGICA SINICA (ENGLISH EDITION), Issue 4 2010
    Wieslaw KRZEMINSKI
    Abstract: A new species, Dactylolabis (Eobothrophorus) hoffeinsorum sp. nov. from the Baltic amber is described, based on one male. The distinctive characters are the shape of the discal cell in the wing and the shape of the process on tergite IX. The description of Dactylolabis (Eobothrophorus) lauryni Podenas, 2003 is amended, based on an additional specimen. With the new species added herein, the number of species of this subgenus totals four. The wing venation, antennae, and tergal processes of all four species of the subgenus described from the Baltic amber are compared. [source]


    Rhyacophila quadrata n. sp., a new caddisfly (Insecta, Trichoptera) from Eocene Baltic amber

    FOSSIL RECORD-MITTEILUNGEN AUS DEM MUSEUM FUER NATURKUNDE, Issue 1 2008
    Wilfried Wichard
    Abstract Rhyacophila quadrata n. sp., a new fossil caddisfly, is described from Eocene Baltic amber. The new species belongs to the family Rhyacophilidae whose extant larvae prefer cool running-water habitats. In Baltic amber, the genus Rhyacophila is now represented by only seven species, whereas more than 500 extant species are described from the Holarctic region. Differences in the biodiversity patterns of the rare fossil faunas and extant species are discussed. ( 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [source]


    A rhabdocoel turbellarian (Platyhelminthes, Typhloplanoida) in Baltic amber with a review of fossil and sub-fossil platyhelminths

    INVERTEBRATE BIOLOGY, Issue 4 2003
    George Poinar Jr.
    Abstract. Palaeosoma balticus n. g., n. sp. (Rhabdocoela, Typhloplanoida), the oldest body fossil of a turbellarian and the first representative of the phylum Platyhelminthes found in fossilized resin, is described from Baltic amber 40 million years old. Characters of the fossil turbellarian are epidermal cilia, rhabdoids, a rosulate pharynx, adhesive papillae, and sensory bristles. The body cavity contains developing eggs or capsules. The fossil demonstrates that rhabdocoels had developed a terrestrial habit and were producing subitaneous eggs by the Eocene. A summary of the fossil and sub-fossil records of platyhelminths is presented. [source]


    The first fossil Bothriocerinae from Eocene Baltic amber with notes on recent taxa (Hemiptera, Fulgoromorpha, Cixiidae)

    MITTEILUNGEN AUS DEM MUSEUM FUER NATURKUNDE IN BERLIN-DEUTSCHE ENTOMOLOGISCHE ZEITSCHRIFT, Issue 2 2002
    Jacek Szwedo
    Abstract The first fossil representative of Bothriocerinae (Hemiptera: Fulgoromorpha: Cixiidae) from Eocene Baltic amber is described. This small group is currently distributed only in the New World. The fossil presents the evidence of a wider distribution of this group in the past. Bothriobaltia pietrzeniukae gen. and sp. n. is described and illustrated. Fossil record of the family, paleogeography of the Eocene, distribution pattern, phylogeny and ecology of the group in view of fossil record are discussed. [source]


    First Mesozoic Scutigeromorph Centipede, from the Lower Cretaceous of Brazil

    PALAEONTOLOGY, Issue 3 2001
    Heather M. Wilson
    The first Mesozoic scutigeromorph centipede (Myriapoda: Chilopoda), Fulmenocursor tenax gen. et sp. nov., is described from the Lower Cretaceous (Aptian) Crato Formation of north-east Brazil. Previously described fossil Scutigeromorpha are known from Dominican and Baltic amber, the Carboniferous (Westphalian D) Francis Creek Shale of Mazon Creek, Illinois, the Silurian and Devonian of Britain, and the Devonian of New York State.

    First Psocodean (Psocodea, Empheriidae) from the Cretaceous Amber of New Jersey

    ACTA GEOLOGICA SINICA (ENGLISH EDITION), Issue 4 2010
    Dany AZAR
    Abstract: Representatives of the extinct psocid family Empheriidae are known from Eocene Baltic amber, Lowermost Eocene French amber (Oise), and Lower Cretaceous Spanish amber (Alava). We report herein the first discovery of an empheriid psocid from the Cretaceous amber of New Jersey as Jerseyempheria grimaldii gen. et sp. nov. The fossil is figured and described. The new species is distinguished from related taxa. A discussion and checklist of Empheriidae are provided. [source]
