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

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]


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]


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

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]


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]

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]
