Cyrtocrinids (Echinodermata,Crinoidea) from Upper Jurassic Štramberk‐type limestones in southern Poland

Abstract: A systematic account of highly diverse cyrtocrinid faunules from Upper Jurassic strata of ?tramberk type (Oxfordian–Tithonian) in southern Poland (Polish Carpathians) is presented. Fourteen taxa (Phyllocrinus malbosianus, Ph. stellaris, Ph. sp., Psalidocrinus armatus, Sclerocrinus compressus, S. polonicus sp. nov., Hemicrinus aff. kabanovi, Ancepsicrinus parvus gen. et sp. nov., Tetracrinus baumilleri sp. nov., Eugeniacrinites alexandrowiczi, E. cf. moravicus, E. sp., Eudesicrinus gluchowskii sp. nov. and Hemibrachiocrinus tithonicus sp. nov. are described and illustrated. Representatives of the genus Eudesicrinus, previously recorded only from the Lower Jurassic, are here shown to extend into the uppermost Jurassic. Other cyrtocrinids considered are common in Jurassic/Cretaceous strata across Europe. In the present faunules, isocrinid (Isocrinida), comatulid (Comatulida) and roveacrinid (Roveacrinida sensu Rasmussen, inclusive of Saccocoma) crinoids are associated.     

New water scavenger beetles (Coleoptera: Hydrophilidae) from the mesozoic of Mongolia

A new genus and two new species of water scavenger beetles, Hydrophilopsia bontsaganica, sp. nov. and Prospercheus cristatus, gen. et sp. nov., are described from the Upper Jurassic and Lower Cretaceous of Mongolia. The systematic position of the new genus is discussed.     

Mesozoic Trachypachidae (Insecta: Coleoptera) from China

Abstract: Four well‐preserved beetles, attributed to Eodromeinae within Trachypachidae, are described from the Mesozoic of Inner Mongolia, China. Eodromeus robustus sp. nov., E. daohugouensis sp. nov. and Unda chifengensis sp. nov. are from the Middle Jurassic of Daohugou. The diagnostic characters for the two genera are revised, and all species of these genera are keyed. A new genus and species, Sinodromeus liutiaogouensis gen. nov., sp. nov., is described from the Lower Cretaceous Yixian Formation of Liutiaogou. The current fossil records of Trachypachidae from China are reviewed, and only five species (four described here) can be convincingly attributed to this family. The morphological disparity of Mesozoic Eodromeinae suggests that they evolved a broad spectrum of locomotory lifestyles.     

Contributions to the study of fossil snipe flies (Diptera: Rhagionidae): The genus Protorhagio

Three new species of the snipe fly genus Protorhagio, viz. P. karataviensis sp. nov., P. ponomarenkoi sp. nov., and P. ruptus sp. nov., are described from the Middle-Upper Jurassic Karabastau Formation in Kazakhstan. The type species of the genus, P. capitatus, is redescribed. A key is provided to all known species of Protorhagio.     

Jurassic lacewings (Insecta: Neuroptera) of Western Siberia

A lacewing assemblage from the Middle Jurassic of the West Siberian Kubekovo locality, the only know Jurassic lacewing fauna of Russia, is discussed. One new genus and two new species of Osmylidae from Kubekovo, Kubekius multiramosus gen. et sp. nov. and Epiosmylus longus sp. nov. are described. Thaumatomerobius mirabilis Ponomarenko, 1985 is transferred to the family Saucrosmylidae, which has only been recorded in the Middle Jurassic of Daohugou.     

Snipe flies (Diptera: Rhagionidae) from the Daohugou Formation (Jurassic), Inner Mongolia,and the systematic position of related records in China

Abstract: Four new species referred to three new genera and one known genus of fossil snipe flies (Family Rhagionidae) from the Daohugou Formation of Chifeng City in Inner Mongolia, north‐eastern China, are described as Daohugorhagio elongatus gen. et sp. nov., Parachrysopilus jurassicus gen. et sp. nov., Sinorhagio sinuatus sp. nov. and Trichorhagio gregarius gen. et sp. nov. These taxa represent only a fraction of the rhagionid assemblage in the Daohugou biota. They contribute towards the high diversity and abundance of snipe flies during the latest Middle Jurassic – earliest Late Jurassic. The diagnosis of Sinorhagio K. Zhang, Yang and Ren, 2006 is revised based on the new results. Many genera and species from the Lower Cretaceous of China have been assigned to Rhagionidae. Most of these do not actually belong to this family: specifically Mesorhagiophryne incerta Hong and Wang, 1990, M. robusta Hong and Wang, 1990, Mesostratiomyia laiyangensis Hong and Wang, 1990, Stratiomyopsis robusta Hong and Wang, 1990, Longhuaia orientalis Hong, Wang and Sun, 1992, Basilorhagio venusius Ren, 1995. Pauromyia oresbia Ren, 1998 is transferred to an archisargid genus as Sharasargus oresbius (Ren, 1998) comb. nov.     

New beetle species of the formal genus <Emphasis Type="Italic">Artematopodites</Emphasis> (Coleoptera: Polyphaga), with remarks on the taxonomic position of the genera <Emphasis Type="Italic">Ovivagina</Emphasis> and <Emphasis Type="Italic">Sinonitidulina</Emphasis>

Three new beetle species of the formal genus Artematopoides, i.e., A. maximus sp. nov., A. crispulus sp. nov., and A. lepidus sp. nov., from the Mongolian Shar-Teg locality are described. Early Jurassic Ovivagina propinqua Zhang, 1997, O. prolixa Zhang, 1997, and O. insculpta Zhang, 1997 from the Junggar Basin (Xinjiang, China) and Middle Jurassic Sinonitidulina longa Hong, 1983 from the Zhouyingzi locality (Hebei, China) are transferred to Artematopoides, and the three species from Xinjiang are redescribed. Ovivagina immediata Zhang, 1997 is synonymized with O. insculpta Zhang, 1997. A new name, Artematopodites leskoviensis Yan, nom. nov., is proposed for A. longus Ponomarenko, 1990, which proved to be a junior secondary homonym of A. longa (Hong, 1983).     

New beetle species of the genus Lasiosyne (Coleoptera, Lasiosynidae) from the Late Jurassic and Early Cretaceous of Russia and Mongolia

Six new species of the genus Lasiosyne Tan et al., 2007, the type genus of the family Lasiosynidae Kirejtshuk et al., 2010, are described from Jurassic and Lower Cretaceous deposits of Mongolia and East Siberia: L. shartegiensis sp. nov., L. insculpta sp. nov., L. longitarsa sp. nov., L. cataphracta sp. nov., L. punctata sp. nov., and L. decora sp. nov. A modified diagnosis of the genus is proposed.     

Pronemouridae fam. nov. (Insecta: Plecoptera), the stem group of nemouridae and notonemouridae,from the Middle Jurassic of Inner Mongolia,China

Abstract: A new family, Pronemouridae fam. nov., with a new genus, Pronemoura gen. nov., and five new species of fossil stoneflies are described from Daohugou village (Middle Jurassic), Inner Mongolia, China: P. shii sp. nov., P. angustithorax sp. nov., P. longialata sp. nov., P. minuta sp. nov. and P. peculiaris sp. nov. Wing venation of pronemourinids presents some or considerable variety in the fore and hind wings of the same or different individuals. Pronemourinidae, retaining plesiomorphic characters (short, multisegmented cerci and CuA with forks), should be treated as the stem group of Nemouridae and Notonemouridae. Based on fossil data, we propose a model in which the extant plecopterid distribution began in the Early Cretaceous. Nemouridae and Notonemouridae must have occurred in Asia and begun to migrate from here by at least the Early Cretaceous.     

Cladistic analysis and taxonomic revision of the genus Karos Goodnight & Goodnight, 1944 (Opiliones,Laniatores, Stygnopsidae)

A cladistic analysis of the genus Karos Goodnight & Goodnight, 1944, was performed using morphological data of the somatic and male genitalia characters. The analysis included 23 terminal taxa, including nine of the 11 described species of the genus plus nine new species according to the previous generic diagnosis and five species as outgroups. According to the topologies obtained by parsimony analyses, the genus is a paraphyletic assemblage, referred here as the Karos genus‐group. Therefore, the genus Karos is rediagnosed here and now includes seven species: Karos barbarikos Goodnight & Goodnight, 1944 (type), Karos parvus Goodnight & Goodnight, 1971, Karos projectus Goodnight & Goodnight, 1971, K aros hexasetosus sp. nov. , K aros monjarazi sp. nov. , K aros singularis sp. nov. , and K aros tersum sp. nov. The genera Monterella Goodnight & Goodnight, 1944, Montabunus Goodnight & Goodnight, 1945, Chapulobunus Goodnight & Goodnight, 1946, and Potosa Goodnight & Goodnight, 1947 are revalidated, rediagnosed, their respective type species are redescribed and the following species are described: Chapulobunus poblano sp. nov. and Potosa reddelli sp. nov. The genera Crettaros gen. nov. , Huasteca gen. nov. , and Mictlana gen. nov. , and the following species are described: Crettaros santibanezi sp. nov. (type), Crettaros valdezi sp. nov. , and Huasteca silhavyi sp. nov. The following new combinations are proposed: Huasteca gratiosa (Goodnight & Goodnight, 1971) comb. nov. (type), Huasteca rugosa (Goodnight & Goodnight, 1971) comb. nov. and Mictlana inops (Goodnight & Goodnight, 1971) comb. nov. (type). Karos brignolii ?ilhavý, 1974, is considered a junior synonym of Huasteca rugosa. Finally, ‘Karos’ depressus Goodnight & Goodnight, 1971 is considered incertae sedis until adult males can be studied. Diagnoses of the Karos and Paramitraceras genus‐groups, and an identification key to the eight genera and 19 species of the former are provided. © 2015 The Linnean Society of London     

Modern hydrophilid clades present and widespread in the Late Jurassic and Early Cretaceous (Coleoptera: Hydrophiloidea: Hydrophilidae)

We present a summary of the fossil evidence documenting the worldwide occurrence of the family Hydrophilidae (Insecta: Coleoptera: Polyphaga: Hydrophiloidea) in the Late Jurassic and Early Cretaceous. We present the first known fossils of the family from the Mesozoic, being c. 100 Myr older than the fossil record available until now. Two Late Jurassic fossils are documented: P rotochares brevipalpis gen. nov., sp. nov. from the Talbragar Fish Bed (New South Wales, Australia) and ‘Mesosperchus’ schultzi Ponomarenko, 1985 from Solnhofen (Bavaria, Germany). The occurrence of the Hydrophilidae in the Early Cretaceous is documented by six species, all of which may be already assigned to modern subfamilies/tribes: B aissalarva hydrobioides gen. nov., sp. nov. from the Baissa outcrops (Buryat Republic, Russia) and C retoxenus australis gen. nov., sp. nov. from Koonwarra outcrops (Victoria, Australia) are both assigned to the tribe Hydrobiusini (Hydrophilinae); A legorius yixianus gen. nov., sp. nov. and Alegorius sp. from the Yixian Formation (Liaoning, China) may represent the Acidocerinae or Enochrinae, H ydroyixia elongata gen. nov., sp. nov. and H . latissima sp. nov. from the same locality are assigned to the Acidocerinae. The phylogenetic position of Baissalarva hydrobioides is also tested by a phylogenetic analysis. The presence of extant clades (Hydrophilinae: Hydrobiusini, Acidocerinae) in the Early Cretaceous and the wide distribution of the Hydrobiusini in both Gondwana and Laurasia at the same time suggests that the principal extant clades of the Hydrophilidae are at least of Early–Middle Jurassic origin. © 2014 The Linnean Society of London     

New species of sap beetles (Coleoptera: Nitidulidae: Epuraeinae,Cybocephalinae) from the Baltic amber

A new genus, Baltoraea gen. nov., two new species of this genus, B. insignis sp. nov. and B. simillima sp. nov., and three other new species, Cybocephalus (Cybocephalus) balticus sp. nov., C. (C.) electricus sp. nov. and C. (C.) kerneggeri sp. nov. are described from the Late Eocene Baltic amber. The systematic position of the genus Baltoraea and presumable bionomics of the new sap beetles are discussed.     

The oldest species of the genus <Emphasis Type="Italic">Glaphyrus</Emphasis> Latr. (Coleoptera: Scarabaeoidea: Glaphyridae) from the Mesozoic of China

Glaphyrus ancestralis sp. nov. is described from the Yixian Formation (Upper Jurassic or Lower Cretaceous). The species is not only one of the earliest records of the family Glaphyridae but also the oldest representative of an extant genus of the family.     

New bugs of the family Archegocimicidae (Hemiptera: Heteroptera) from the Upper Jurassic of Mongolia

Two new genera and five new species of Archegocimicidae are described from the Upper Jurassic of the Shar-Teg locality in Mongolia: Shartegocimex rasnitsyni, gen. et sp. nov., S. distans, sp. nov., Shartegocorpus paranotalis, gen. et sp. nov., Saldonia formosa, sp. nov., S. insolita, sp. nov.     

New species of sap beetles (Coleoptera: Nitidulidae: Nitidulini) from the Baltic and Bitterfeld ambers

A new genus, Microsoronia, gen. nov., and new species of this genus, M. hoffeinsorum, sp. nov. from the Bitterfeld amber and M. kerneggeri sp. nov., M. nigerrima sp. nov., and M. interfax, sp. nov. from the Baltic amber, are described. The earliest known member of the genus Phenolia, P. (Lasiodites) angustitibialis, sp. nov., is described from the Baltic amber. The systematic position of these two genera, their possible evolution, as well as the possible ecology and bionomics of their members are discussed. It is shown that “Phenolia” incapax Scudder, 1890 should be included in the family Peltidae, rather than Nitidulidae.     

FIRST RECORD OF FOSSIL CRICKETS (ORTHOPTERA:TRIGONIDIIDAE) FROM CHINA*

Abstract A new genus and a new species of fossil nemobiins, Liaonemobius tanae gen. et sp. nov., are described and illustrated. This is the first record of fossil cricket from China. All the specimens described here were collected from the Late Jurassic Yixian Formation of West Liaoning, China, and now are deposited in the National Geological Museum of China, Beijing.     

Revision and description of water boatmen from the Middle-Upper Jurassic of Northern and Northeastern China (Insecta: Hemiptera: Heteroptera: Corixidae)

Four adult and immature water boatmen from the Middle Jurassic and uppermost Middle Jurassic or lowermost Upper Jurassic Jiulongshan, Haifanggou and Daohugou formations in the northern and northeastern China are described as Yanliaocorixa chinensis (Lin, 1976), Jiulongshanocorixa genuina gen. et sp. nov., and Daohugocorixa vulcanica gen. et sp. nov., referred to the extinct subfamily Velocorixinae, and Karataviella popovi sp. nov., referred to the extant subfamily Diaprepocorinae. All the forms have previously been identified as one species, Yanliaocorixa chinensis. This species, found only in the Haifanggou Formation, is absent from the Jiulongshan Formation and other sites in China. The systematic position of corixids recorded earlier from the Mesozoic of China is reviewed and reassessed. Assemblages of dominant aquatic insects from various Jurassic nonmarine sedimentary basins in northern and northeastern China are described for the first time. They are entirely different between the Jiulongshan, Haifanggou, and Daohugou formations. The first formation is probably older than the other two.     

Hemibranchiate sphaeromatids (Crustacea: Isopoda) from Queensland, Australia, with a world-wide review of the genera discussed

All known Queensland species of the isopod family Sphaeromatidae, subfamily Sphaeromatinae (= hemibranchs), are discussed. The following new taxa are erected: Calcipila cornuta, gen. nov., sp. nov. ; Cymodoce tribullis, sp. nov. ; Cymodoce bipapilla, sp. nov. ; Paracilicaea aspera, sp. nov. ; Cilicaeopsis glebosa, sp. nov. ; Cilicaeopsis furculata, sp. nov. ; Cilicaea calcarifera, sp. nov. ; Zuzara curtispina, sp. nov. ; Zuzara digitata, sp. nov. ; and Clianella brucei, sp. nov. Exosphaeroma intermedium Baker is transferred to the genus Sphaeroma Latreille. The genus Dynoides Barnard is reviewed and its current synonymy is contested. With several new records, this brings the total number of sphaeromatid species known from Queensland to 49, 24 of which are in the subfamily Sphaeromatinae. A checklist of all sphaeromatid species occurring in Queensland waters is given. From the rest of Australia: Cymodoce tuberculata Haswell is given the replacement name Cymodoce haswelli, nom. nov. ; Cymodoce granulata Miers is made a junior synonym of Cerceis trispinosa (Haswell) (subfamily Dynameninae); Zuzara diadema Leach, Z. dicantha (Milne Edwards) and Z. Integra Haswell are made junior synonyms of Z. semipunctata Leach; Cilicaeopsis dakini Tattersall is tentatively transferred to the genus Paracilicaea Stebbing. The genera discussed are reviewed world-wide and among the non-Australian species: Exosphaeroma papillae Bayliff is transferred to the genus Sphaeroma; Sphaeroma irakiensis Ahmed is made a junior synonym of Sphaeroma annandalei annandalei Stebbing; Cymodoce richardsoniae Nobili is shown to be distinct from Cymodoce truncata Leach; Cymodoce eupyga Nobili is transferred to the genus Paracilicaea; Dynoides amblysinus Pillai, Dynoides castroi Loyola e Silva and Exosphaeroma globicaudum (Dana) are transferred to the genus Clianella Boone; Dynoides brasiliensis (Loyola e Silva; and Sphaeroma savignn Milne Edwards sensu Dana, 1853 are declared to be conspecific with Clianella castroi. The name Sorrentosphaera Verhoeff is made a junior synonym of Dynamene Leach (subfamily Dynameninae.     

The earliest known Salamanders (Amphibia,Caudata):A record from the Middle Jurassic of England

Marmorerpeton gen. nov. represented by M. kermackisp. nov. and M. freemani sp. nov., is the earliest known genus of fossil salamander from the Upper Bathonian, Middle Jurassic of Kirtlington, Oxfordshire, England. Marmorerpeton is more primitive than any other known salamander in the absence of intravertebral spinal nerve foramina in the atlantal centrum, but in other features it resembles members of the family Scapherpetontidae, neotenous salamanders otherwise known from the Upper Cretaceous and Palaeocene. The Kirtlington herpetofauna is a unique freshwater assemblage of Middle Jurassic small amphibians and reptiles, several of which represent the earliest known occurrences of their respective groups.     

Cladistics and revision of Alitocoris with considerations on the phylogeny of the Herrichella clade (Hemiptera,Pentatomidae, Discocephalinae,Ochlerini)

Alitocoris Sailer, 1950, consists of four valid species described from Central America. In a recent cladistic analysis of Ochlerini, the genus was considered paraphyletic in the Herrichella Distant, 1911, group of taxa. The present study provides a cladistic analysis of the Herrichella clade, using 88 morphological characters and 40 taxa representing 21 genera of Ochlerini, including all known species of Alitocoris plus 16 new species. Outgroups included Eritrachys bituberculata Ruckes, 1959, Phereclus pluto Stål, 1862, and Adoxoplatys comis Breddin, 1903, with the last used for rooting. The cladistic analysis was conducted using TNT under heuristic searches and implied weighting of characters; 11 K‐values calculated for an average character fit ranged from 50 to 90% of a perfectly hierarchical character. The results corroborated the paraphyly of Alitocoris, calling for changes in the classification of the genus with the proposition of three new genera for two, three, and ten species, respectively, that will be described elsewhere. Alitocoris is redescribed and a key for the species is presented. Alitocoris brunneus, Alitocoris maculosus, and Alitocoris parvus are removed from the genus, and the new species Alitocoris grandis sp. nov. , Alitocoris lateralis sp. nov. , and Alitocoris ornatus sp. nov. are described. © 2013 The Linnean Society of London
