Gall midges of the supertribe stomatosematidi (Diptera,Cecidomyiidae) in the Palaearctic region,with descriptions of new taxa from the late Eocene Rovno Amber. 2. The genera <Emphasis Type="Italic">Didactylomyia</Emphasis> and <Emphasis Type="Italic">Rovnodidactylomyia</Emphasis> gen. n.

One new genus (Rovnodidactylomyia Fedotova et Perkovsky, gen. n.) and four new species (Didactylomyia dlusskyi sp. n., Rovnodidactylomyia zosimovichi gen. n. et sp. n., R. sidorenkoi sp. n., and R. iconica sp. n.) are described from an amber sample of the late Eocene Period (Rovno District, Ukraine). Two species from a Baltic amber sample of the late Eocene Period, described earlier in the genus Bryocrypta, are attributed to the genus Rovnodidactylomyia (R. girafa (Meunier, 1904) comb. n. and R. capitosa (Meunier, 1904)). The first fossil species of the genus Didactylomyia is described for the first time; two contemporary Palaearctic species are recorded. Keys to the species of the genus Didactylomyia are given.     

Gall midges of the supertribe Stomatosematidi (Diptera,Cecidomyiidae) in the Palaearctic Region,with descriptions of new taxa from the Late Eocene Rovno amber: 1. <Emphasis Type="Italic">Stomatosema,Vanchidiplosis, Clarumreddera</Emphasis> gen. n.

Three recent genera are included in the supertribe Stomatosematidi: Stomatosema (16 species), Vanchidiplosis (4 species), and Didactylomyia (3 species). Seven species of the genus Stomatosema and two species of the genus Vanchidiplosis occur in the Palaearctic Region. No reliable findings of representatives of the supertribe were known in fossilized condition. One new genus and 3 new species are described from amber of the Late Eocene age (Rovno Region): Stomatosema iljieteugeniae sp. n., Clarumreddera korneyevi gen. n. et sp. n., and C. conceptiva sp. n.     

New and little-known orthopteroid insects (Polyneoptera) from fossil resins: Communication 4

New taxa of Ensifera and Caelifera orthopterans (Insecta, Orthoptera), from the families Gryllotalpidae [Marchandiinae, subfam. nov. (Lower Cretaceous)], Haglotettigoniidae [?Haglotettigonia aenigmatosa, sp. nov. (Lower Cretaceous)], Tettigoniidae [Meconematinae: Archixizicus occidentalis, gen. et sp. nov. (Eocene), Eogrigoriora gracilis, gen. et sp. nov. (Eocene), Miophlugis rostratus, gen. et sp. nov. (Miocene)], Stenopelmatidae [Siinae: Electrosia baltica, gen. et sp. nov. (Eocene); Gryllacridinae: Plesiolarnaca prior, gen. et sp. nov. (Eocene)] and Tridactylidae [Mongoloxyinae: Birmitoxya intermedia, gen. et sp. nov. (Upper Cretaceous). The Eocene species Lipotactes martynovi Zeun. and L. bispinatus Weidn. are transferred to the genus Eomortoniellus Zeun. (Tettigoniidae: Tympanophorinae); Prorhaphidophora zeuneri Chop. and P. tachycinoides Chop. are transferred to the genus Protroglophilus Gor. (Rhaphidophoridae: Protroglophilinae). The Eocene species E. handlirschi Zeun., species of the genus Protroglophilus, and a possible member of the genus Succinotettix Piton (Tetrigidae: Tetriginae), as well as a Miocene representative of the genus Archaeoellipes Heads (Tridactylidae: Tridactylinae) are also discussed.     

<Emphasis Type="Italic">Weitschataster intermedius</Emphasis> gen. et sp. nov., a goniasterid starfish (Echinodermata: Asteroidea) from the Upper Cretaceous of Germany

Weitschataster intermedius gen. et sp. nov., is described from the Upper Campanian (Upper Cretaceous) of Hannover (Lower Saxony, N Germany). The new species is characterized by its conspicuous rimmed pedicellariae scars covering almost the complete actinal surface and by small body size. W. intermedius represents a transitional state between W. decipiens comb. nov. from the Lower Campanian and the well-known W. undulatus comb. nov. from the Lower Maastrichtian of NW Europe. Among Spencer’s types of W. undulatus, one paratype is recognized as belonging to the genus Parametopaster.     

A Review of the Fauna of the Planthopper Family Lophopidae (Homoptera,Fulgoroidea) from Vietnam with Descriptions of New Genera and Species and with Taxonomic Notes

Six new species are described from Vietnam, Apia simplexsp. n., Bisma angulatasp. n., Pitambara trypetoidessp. n., Sarmatoca cathemerinagen. et sp. n., Maracota soulieraegen. et sp. n., and Serida castaneasp. n., and Zeleja thoracalissp. n. from Malaysia. Two new genera, Maracotagen. n. (type species M. soulierae sp. n.) and Sarmatocagen. n. (type species S. cathemerina sp. n.), and a new subgenus Zelomachasubgen. n. (type species Zeleja thoracalis sp. n.) in the genus Zeleja are erected. The genus Binaluana Soulier-Perkins et Stroiński is downgraded to a subgenus of Zeleja Melichar. The genus Silvispina Wang et Soulier-Perkins with an uncertain systematic position is attributed to the subfamily Lophopinae and the tribe Lophopini. The placement of the genus Elasmoscelis Spinola (and, correspondingly, the tribe Elasmoscelini) in the subfamily Menoscinae, the genus Epiptyxis Gerstaecker in the tribe Menoscini, and the genus Jivatma Melichar in the tribe Lophopini is substantiated. New records of 11 species are given from Vietnam, some being first records for this country.     

<Emphasis Type="Italic">Kunduriphyllum kundurense</Emphasis> gen. et comb. nov. (Platanaceae) and Associated Reproductive Structures from the Campanian of the Amur Region,Russia

Fossil leaves and associated reproductive structures from the Kundur locality, Amur Region, are examined. A new genus of the unlobed platanaceous leaves, Kunduriphyllum gen. nov. (Platanaceae) is described based on distinctive morphological and epidermal features. The similarity of epidermal characteristics and identical biological damage suggest that the leaves Kunduriphyllum kundurense gen. et comb. nov., staminate inflorescences Kundurianthus, and infructescences Kunduricarpus could be assigned to a single plant.     

<Emphasis Type="Italic">Sporidesmioides thailandica</Emphasis> gen. et sp. nov. (Dothideomycetes) from northern Thailand

Sporidesmioides thailandica gen. et sp. nov., isolated from herbaceous litter in northern Thailand, is described and illustrated. The new genus is characterised by sporidesmium-like, septate, solitary, acrogenous, pale brown to brown, obclavate, conidia, which taper towards the apex and are truncate at the base and septate conidiophores similar to those of Sporidesmium species in Sporidesmiaceae (Sordariomycetes). It differs from similar genera by the presence of a stromatic base, polyblastic conidiogenous cells and a distinct, colourless sheath at the conidial apex. Phylogenetic analyses of combined LSU, SSU, TEF1-α and RPB2 sequence data show that the new taxon, Sporidesmioides thailandica, forms a separate, single clade with Torulaceae in Pleosporales, Dothideomycetes, and is distinct from Sporidesmiaceae (Sordariomycetes).

New jewel beetles (Coleoptera: Buprestidae) from the Cretaceous of Russia,Kazakhstan, and Mongolia

A new jewel beetle genus, with one species (Cretofrontolina kzyldzharica gen. et sp. nov.) from the Upper Cretaceous of Kazakhstan is described based on a body; and three new species of the formal genus Metabuprestium are described based on isolated elytra: Metabuprestium sibiricum sp. nov. and M. arkagalense sp. nov. come from the Arkagala locality (Upper Cretaceous of Russia) and M. ichbogdense sp. nov. is from the Shar Tologoi locality (Lower Cretaceous of Mongolia).     

Addenda to the Revisions of the Genera <Emphasis Type="Italic">Gergithus</Emphasis> Stål and <Emphasis Type="Italic">Hemisphaerius</Emphasis> Schaum (Hemiptera,Auchenorrhyncha, Fulgoroidea: Issidae)

The genus Gnezdilovius Meng, Webb et Wang, 2017 is revised. Maculergithus Constant et Pham, 2016, which was described as a subgenus of Gergithus Stål, 1870, is upgraded to a genus. Ishiharanus Hori, 1969 is reinstalled from synonymy with Gergithus and considered a valid name. Two new genera are erected, Ceratogergithus Gnezdilov, gen. n. (type species: Gergithus spinosus Che, Zhang et Wang, 2007) and Ophthalmosphaerius Gnezdilov, gen. n. (type species: Hernisphaerius trilobulus Che, Zhang et Wang, 2006). Hernisphaerius bistriatus Schumacher, 1915, Gergithus carbonarius Melichar, 1906, G. rosticus Chan et Yang, 1994, G. nummarius Chan et Yang, 1994, and G. rotundus Chan et Yang, 1994 are transferred to the genus Epyhemisphaerius Chan et Yang, 1994, Gergithus quinquemaculatus Che, Zhang, Wang, 2007—to the genus Maculergithus, Gergithus chelatus Che, Zhang, Wang, 2007 and G. pseudotessellatus Che, Zhang, Wang, 2007—to the genus Ceratogergithus, Hernisphaerius binocularis Chen, Zhang, Chang, 2014—to the genus Ophthalmosphaerius, and Gergithus robustus hoozanensis Schumacher, 1915—to the genus Gnezdilovius. The male genitalia of Gergithus herbaceus (Kirby, 1891) and Hernisphaerius interclusus Noualhier, 1896 are illustrated for the first time.     

Notes on the phylogenetic relationships of planthoppers of the family issidae (Hemiptera,Fulgoroidea) of the Western Palaearctic fauna,with descriptions of two new genera

Seven groups of genera are distinguished in the subtribe Issina Spinola. The new genera Apedalmus gen. n. (the type species Falcidius abruzicus Dlabola, 1983) and Thalassana gen. n. (the type species: Hysteropterum ephialtes Linnavuori, 1971) are erected. The subgenera Acrestia Dlabola, 1980, Montissus Gnezdilov, 2003, and Atticus Gnezdilov, 2003 are upgraded to genera. The subgenus Capititudes Gnezdilov, Drosopoulos et Wilson, 2004 is transferred to the genus Acrestia, and the subgenus Stygiata Emeljanov, 1972 to Celyphoma Emeljanov, 1971. The subtribe Agalmatiina Gnezdilov, 2002 and the subfamily Hysteropterinae Melichar, 1906 are placed in synonymy under Issina Spinola, 1839. Issus reticulatus Herrich-Schäffer, 1835 is designated as the type species of the genus Hysteropterum Amyot et Serville, 1843.     

A new genus of seed beetles (Coleoptera,Chrysomelidae, Bruchinae) in Baltic amber

The new genus and new species of seed beetles (Copeoptera, Chrysomelidae, Bruchinae) Electrocaryedon poinari gen. et sp. nov. are described from the Late Eocene Baltic amber. This new genus differs from the genus Caryedon Schoenherr, 1823 in the completely separate procoxal cavities, not shortened lateral carina on pronotum, and wider body with sparse setae.     

<Emphasis Type="Italic">Protocopidosoma</Emphasis> gen. nov. (Hymenoptera,Chalcidoidea, Encyrtidae) from the Late Eocene Danish amber

Protocopidosoma kononovae gen. et sp. nov. from Danish amber is described. The specimen is very similar to representatives of the extant genus Copidosoma Ratzeburg, 1844 and differs from them in the long and wide veins in the forewing, as in most encyrtids from Late Eocene European ambers.     

<Emphasis Type="Italic">Oredezhosteus</Emphasis>, a new psammosteid genus (Heterostraci,Psammosteiformes) from the Lower Frasnian (Upper Devonian) of the Main Devonian Field

A new psammosteid, Oredezhosteus kuleshovi gen. et sp. nov., from the Amata Regional Stage (Lower Frasnian) of the Leningrad Region is described. In addition, Psammosteus livonicus Obruchev from beds of the same age from Latvia is included in the new genus. The major diagnostic characters distinguishing Oredezhosteus gen. nov. from Psammosteus Agassiz are the large rounded striated tubercles, which cover more than half width of the branchials, and the long base of the branchial plates.     

The genus <Emphasis Type="Italic">Fusariella</Emphasis>

The genus Fusariella, typified by F. atrovirens, is characterised by semi- to macronematous, mononematous conidiophores, with cylindrical, subulate or lageniform phialidic conidiogenous cells that produce catenate, septate, curved to straight, subhyaline to brown conidia. During a survey of hyaline-spored hyphomycetes from karst areas in Thailand, we collected a new species of Fusariella with curved conidia and introduce it in this paper as Fusariella curvata sp. nov. In addition, all hitherto described species of Fusariella are reviewed. The result of phylogenetic analyses, based on combined SSU, LSU, TEF and RPB2 sequence data, indicates that the genus belongs in the family Bionectriaceae (Hypocreales, Sordariomycetes).     

On the taxonomic position of <Emphasis Type="Italic">Issus reticulatus</Emphasis> Bervoets, 1910 (Hemiptera: Fulgoroidea: Issidae) from Baltic amber

A new genus Bolbossus gen. n. is erected in the tribe Parahiraciini for Issus bervoetsi Gnezdilov et Bourgoin, nom. n. pro Issus reticulatus Bervoets, 1910 (nom. praeocc., non Issus reticulatus Herrich-Schäffer, 1835) described from the Baltic amber of Kaliningrad Province in Russia. The genus Issites Haupt, 1956 is assigned to the nominotypical subtribe of the tribe Issini Spinola. Bolbossus bervoetsi (Gnezdilov et Bourgoin) is the first species of the Oriental tribe of the family Issidae discovered in Europe. This finding implies the dispersal of taxa from the Oriental Region to the Western Palaearctic during the Eocene. Other fossil Issidae are briefly discussed.     

The genus <Emphasis Type="Italic">Keppleritiana</Emphasis> gen. nov. (Stephanoceratidae,Ammonoidea) from the Upper Bajocian of the Northern Caucasus

A new ammonite genus of the subfamily Garantianinae, family Stephanoceratidae, from the Upper Bajocian Strenoceras niortense Zone in the Bolshoi Zelenchuk River basin (Karachay-Cherkessia), with two new species from two different localities, is established. The type species Keppleritiana rostovtsevi gen. et sp. nov. is homeomorphic to some species of the Upper Bathonian–Lower Callovian genus Kepplerites (Fam. Kosmoceratidae) but is distinguished by the presence of a ventral furrow in adults. An isolated valve of an aptychus possibly belonging to this species is illustrated. Keppleritiana graebensteini sp. nov. has a more archaic morphology and is apparently ancestral to the type species. The macroconchs and microconchs of both species are described.     

New and little known orthopteroid insects (polyneoptera) from fossil resins: Communication 2

New taxa of the suborder Blattina (order Dictyoptera), possibly belonging to the family Corydiidae (Erucoblatta semicaeca gen. et sp. nov., Miocene; Proholocompsa gen. nov., Eocene; and Holocompsa nigra sp. nov. and H. abbreviata sp. nov., Miocene) and belonging to the family Ectobiidae (Plectoptera electrina sp. nov., Miocene; Agrabtoblatta symmetrica gen. et sp. nov. and ?Symploce rete sp. nov., Pleistocene) are described. The taxonomic position of the enigmatic genus Raphidiomimula Grimaldi et Ross from the Upper Cretaceous is discussed.     

On the taxonomic state of a digger wasp of the tribe Crabronini (Hymenoptera,Crabronidae, Crabroninae) from the Dominican amber

“Lindenius paleomystax” described from the Miocene Dominican amber has been included into a separate digger wasp genus, Lindocerus gen. nov. (Crabronidae, Crabroninae, Crabronini), which is similar to the genus Crossocerus Lepeletier de Saint Fargeau et Brullé, 1835, but differs in the well-pronounced hypersternaulus.
