    A new genus and species of Aleurodicinae whiteflies from the Eocene Baltic amber is described. Medocellodes blackmani Drohojowska et Szwedo gen. et sp. nov. is the second representative of Aleurodicinae from Baltic amber, presenting mixture of plesiomorphic characters, as retention of median ocellus, with apomorphic states, shared also with other contemporaneous Aleurodicinae from Rovno amber. Morphological characters of the newly described fossil are briefly discussed.  
    Abstract A planthopper originally assigned to the genus Boreocixius in Surijokocixiidae (Surijokocixioidea, Fulgoromorpha) from the Ladinian (Middle Triassic) of Tongchuan in Shaanxi, northwestern China is described as Boreocixius... more
    Abstract A planthopper originally assigned to the genus Boreocixius in Surijokocixiidae (Surijokocixioidea, Fulgoromorpha) from the Ladinian (Middle Triassic) of Tongchuan in Shaanxi, northwestern China is described as Boreocixius tongchuanensis Zhang et al. sp. nov. As the third species ascribed to the genus, it differs from its congeners in having the much larger tegmen with postnodal veinlets and pigmented bands, providing new morphological information for Boreocixius. The establishment of the new species further increases the diversity of Boreocixius and Surijokocixiidae as well.

    Four new fossil species of haematophagous biting midges of the genus Culicoides Latreille, from mid-Cretaceous Burmese amber are described and illustrated: C. bojarskii Szadziewski & Dominiak sp. nov., C. burmiticus Szadziewski & Dominiak sp. nov., C. ellenbergeri Szadziewski & Dominiak sp. nov. and C. myanmaricus Szadziewski & Dominiak sp. nov. These extinct species are assigned to the new subgenus, Groganomyia Szadziewski & Dominiak subgen. nov. which also includes an extant species that inhabits European mountains, Culicoides cameroni Campbell & Pelham-Clinton, 1960, the type species. These very old (99 Ma) haematophagous biting midges of the extant genus Culicoides from Burmese amber supports the hypothesis that most groups of modern biting midges evolved during the mid-Cretaceous greenhouse climate.

    The tropiduchid monotypic genus Laberia Stål, 1866, endemic to Madagascar, is placed in a new tribe of its own Laberiini trib. nov. The tribe is placed in the subfamily Elicinae, and can be distinguished from other representatives of the subfamily by the unique combination of morphological characters of the head, tegmina, legs and genital structures. The genus Laberia and its only species Laberia palliata Stål, 1866 are redescribed, chresonymy is presented and nomenclatorial questions are clarified. Distributional data from Madagascar and doubtful presence of the taxon in Mauritius are discussed. Taxonomic content of Elicinae is briefly discussed.

    Fossils are critical for understanding the evolutionary diversification, turnover, and morphological disparification of extant lineages. While fossils cannot be sequenced, phenome-scale data may be generated using micro-computed tomography (µ-CT), thus revealing hidden structures and internal anatomy, when preserved. Here, we adduce the male caste of a new fossil ant species from Miocene Ethiopian amber that resembles members of the Aneuretinae, matching the operational definition of the subfamily. Through the use of synchrotron radiation for µ-CT, we critically test the aneuretine-identity hypothesis. Our results indicate that the new fossils do not belong to the Aneuretinae, but rather the Ponerini (Ponerinae). Informed by recent phylogenomic studies, we were able to place the fossils close to the extant genus Cryptopone based on logical character analysis, with the two uniquely sharing absence of the subpetiolar process among all ponerine genera. Consequently, we: (1) revise the ...

    The Early Miocene (16–23 Mya) amber of Ethiopia constitutes a new source of fossil ants for Africa, where they are otherwise poorly documented. Here we report a diversified assemblage of six subfamilies and at least 19 genera that are still predominantly alive in the Afrotropics today. In this first account, a particular reference is made to the subfamily Dolichoderinae, with the description of two new species: Technomyrmex svojtkai Perrichot & Engel sp. nov. and Ravavy goldmani Boudinot & Perrichot sp. nov. The first is illustrated and described based on synchrotron-radiation microcomputed tomography, and the second represents the first fossil record for the tribe Bothriomyrmecini and Ravavy, a Malagasy and Afrotropical genus that was hitherto monotypic. The ant composition in Ethiopian amber is congruent with the global pattern emerging across ants and showing a Neogene diversification almost exclusively within extant genera.
    Fossil new genus and species Afroscatopse haennii gen. et sp. nov. from Miocene Ethiopian amber are described and illustrated and placed in the tribe Colobostematini. The gigantic adults of this scavenger fly, largest within the family,... more
    Fossil new genus and species Afroscatopse haennii gen. et sp. nov. from Miocene Ethiopian amber are described and illustrated and placed in the tribe Colobostematini. The gigantic adults of this scavenger fly, largest within the family, with dull body, long antennae and broad wings evidently were adapted to live on bark of trees. It is suggested that it was a myrmecophilous species with larvae living in the nests of tree ants.

    Abstract A new genus and species of planthopper, Lanlakawa changdaensis gen. et sp. nov., is described based on a well-preserved specimen from mid-Cretaceous Kachin (Burmese) amber. This is the ninth genus of the extinct family Perforissidae and the sixth genus of the subfamily Cixitettiginae. The new genus mainly differs from the five previously described genera in tegmen venation and the number of teeth in tibial pectens. Previous researches of sensory pits and wing-coupling apparatus are briefly reviewed.

    A new fossil ceratopogonid genus and species from Lower Cretaceous Lebanese amber, Baskintoconops maaloufi Pielowska-Ceranowska gen. et sp. nov., is described and illustrated. The studied material originates from a newly discovered amber site in the Lebanese village Baskinta at a locality dubbed Qanat Bakish. The described genus is typified by its wing venation pattern combining characters of genera Fossileptoconops and Jordanoconops belonging to the subfamily Leptoconopinae.

    ABSTRACT Here we describe and illustrate a new genus and species of the extinct froghopper family Sinoalidae, Cretomultinervis burmensis gen. et sp. nov. from Burmese (Myanmar) amber. The new genus can be recognized from all sinoalids by the combination of hind tibia armed with five interlaced lateral spines, leaf-shaped tegmen with very broad postcostal cell, basal cell extremely long, hindwing with costal margin armed with 5 micro-spines basally, cross vein mp-cua apparently basad of stem CuA fork. This peculiar combination of primitive and derived characters suggests that Cretomultinervis likely represents an early-diverging lineage of Sinoalidae, increasing our knowledge on the morphological disparity of this extinct family during the late Mesozoic.
