Background

Lacewings (insect order Neuroptera), known in the fossil record since the Early Permian, were most diverse in the Mesozoic. A dramatic variety of forms ranged in that time from large butterfly-like Kalligrammatidae to minute two-winged Dipteromantispidae.

Principal Findings

We describe the intriguing new neuropteran family Parakseneuridae fam. nov. with three new genera and 15 new species from the Middle Jurassic of Daohugou (Inner Mongolia, China) and the Early/Middle Jurassic of Sai-Sagul (Kyrgyzstan): Parakseneura undula gen. et sp. nov., P. albomacula gen. et sp. nov., P. curvivenis gen. et sp. nov., P. nigromacula gen. et sp. nov., P. nigrolinea gen. et sp. nov., P. albadelta gen. et sp. nov., P. cavomaculata gen. et sp. nov., P. inflata gen. et sp. nov., P. metallica gen. et sp. nov., P. emarginata gen. et sp. nov., P. directa gen. et sp. nov., Pseudorapisma jurassicum gen. et sp. nov., P. angustipenne gen. et sp. nov., P. maculatum gen. et sp. nov. (Daohugou); Shuraboneura ovata gen. et sp. nov. (Sai-Sagul). The family comprises large neuropterans with most primitive wing venation in the order indicated by the presence of ScA and AA1+2, and the dichotomous branching of MP, CuA, CuP, AA3+4, AP1+2. The phylogenetic position of Parakseneuridae was investigated using a phylogenetic analysis of morphological scoring for 33 families of extinct and extant Neuropterida combined with DNA sequence data for representatives of all extant families. Parakseneuridae were recovered in a clade with Osmylopsychopidae, Prohemerobiidae, and Ithonidae.

Conclusions/Significance

The presence of the presumed AA1+2 in wings of Parakseneuridae is a unique plesiomorphic condition hitherto unknown in Neuropterida, the clade comprising Neuroptera, Megaloptera, Raphidioptera. The relative uncertainty of phylogenetic position of Parakseneuridae and the majority of other families of Neuroptera reflects deficient paleontological data, especially from critical important periods for the order, earliest Triassic and latest Triassic/earliest Jurassic.  相似文献

New form taxa of insect ovipositions on aquatic plant leaves Quereuxia from the Campanian locality of Udurchukan (Amur Region) are described. Endophytic ovipositions Paleoovoidus flabellatus sp. nov. and P. arcuatus sp. nov. do not differ in shape from ovipositions of recent damselflies. Exophytic ovipositions Palaexovoidus ovoideus gen. et sp. nov., P. catenulatus sp. nov., P. multus sp. nov., and P. amplus sp. nov. belong to insects that develop in the water, probably dragonflies of the suborder Anisoptera. A new family Palaexovoididae fam. nov. is erected.  相似文献

Triassic radiolarians from Kotel’nyi Island (New Siberian Islands, Arctic Region) are studied. Radiolarians occur in the Middle and Upper Triassic beds, which are well dated by ammonoids, nautiloids, and bivalves. In the Middle Triassic beds, which are composed of dark gray and black clays and claystones with interbeds of combustible schist, siltstone, clayey limestone, and many phosphatic concretions, the following two assemblages are recognized: (1) a Late Anisian assemblage, including Glomeropyle clavatum Bragin, sp. nov., G. boreale Bragin, G. manihepuaensis Aita, G. insulanum Bragin, sp. nov., Triassospongosphaera multispinosa (Kozur et Mostler), Tetraspongodiscus hibernus Bragin, sp. nov., T. borealis Bragin, sp. nov., Eptingium abditum Bragin, sp. nov., E. manfredi Dumitrica, Spongostephanidium japonicum (Nakaseko et Nishimura), and Ladinocampe vicentinensis Kozur et Mostler; (2) Late Ladinian assemblage, with Muelleritortis firma (Gorican), M. kotelnyensis Bragin, sp. nov., Tiborella nivea Bragin, sp. nov., Pseudostylosphaera goestlingensis (Kozur et Mostler), P. omolonica Bragin, Triassospongosphaera multispinosa (Kozur et Mostler), Sarla cincinnata Bragin, sp. nov., S. obscura Bragin, sp. nov., S. prava Bragin, sp. nov., and Eonapora stiriaca Bragin, sp. nov. The Upper Triassic beds, composed of gray and black clays and claystones with lenses of clayey limestones, with sideritic and phosphatic-calciferous concretions have yielded (1) an Early Carnian assemblage, with Pentactinocarpus colum Bragin, sp. nov., Glomeropyle cuneum Bragin, sp. nov., G. algidum Bragin, sp. nov., G. aculeatum Bragin, sp. nov., Kahlerosphaera isopleura Bragin, sp. nov., Stauracanthocircus folium Bragin, sp. nov., Tetraspongodiscus uncatus Bragin, sp. nov., Poulpus costatus (Kozur et Mostler), Eonapora robusta Kozur et Mostler, Planispinocyrtis kotelnyensis Bragin, sp. nov., Annulotriassocampe baldii (Kozur), and Pseudoeucyrtis annosus Bragin, sp. nov.; (2) a Middle-Late Carnian assemblage with Pseudostylosphaera glabella Bragin, sp. nov., P. gracilis Kozur et Mock, P. voluta Bragin, sp. nov., P. gelida Bragin, sp. nov., Kahlerosphaera unca Bragin, sp. nov., K. aspinosa Kozur et Mock, K. fuscinula Bragin, sp. nov., K. acris Bragin, sp. nov., Capnuchosphaera kuzmichevi Bragin, sp. nov., C. triassica De Wever, C. angusta Bragin, sp. nov., Sarla intorta Bragin, sp. nov., S. compressa Bragin, sp. nov., S. aequipeda Bragin, sp. nov., Betraccium irregulare Bragin, B. kotelnyensis Bragin, sp. nov., Spongotortilispinus carnicus Kozur et Mostler, S. subtilis Bragin, sp. nov., Dumitricasphaera simplex Tekin, D. aberrata Bragin, sp. nov., D. arbustiva Bragin, sp. nov., Zhamojdasphaera epipeda Bragin, sp. nov., Z. proceruspinosa Kozur et Mostler, Vinassaspongus subsphaericus Kozur et Mostler, Palaeosaturnalis triassicus Kozur et Mostler, Paronaella concreta Bragin, sp. nov., P. aquilonia Bragin, sp. nov., Tetraspongodiscus cincinnalis Bragin, sp. nov., Annulotriassocampe baldii (Kozur), Canoptum zetangense Wang et Yang, Whalenella speciosa (Blome), Syringocapsa turgida Blome, Droltus gelidus Bragin, sp. nov., and D. niveus Bragin, sp. nov.; (3) an Early Norian assemblage with Pseudostylosphaera glabella Bragin, sp. nov., P. gelida Bragin, sp. nov., P. voluta Bragin, sp. nov., Kahlerosphaera retunsa Bragin, sp. nov., Capnuchosphaera deweveri Kozur et Mostler, Sarla globosa Bragin, sp. nov., Palaeosaturnalis mocki Kozur et Mostler, Paronaella aquilonia Bragin, sp. nov., Syringocapsa turgida Blome, and Droltus gelidus Bragin, sp. nov.; (4) a Middle Norian assemblage with Sarla globosa Bragin, sp. nov., Sarla sp., Syringocapsa turgida Blome, Canoptum sp., and Laxtorum? sp. The fact that these assemblages include taxa that are recorded more southerly, including paleotropical localities, and support dating based on mollusks, enables the use of these data for Boreal-Tethyan correlation. The greatest similarity to Tethyan associations is observed in the Late Carnian and Early Norian, that is, the periods of the greatest penetration of thermophilic mollusks into this basin. A total of 69 radiolarian species of 3 orders, 18 families, and 29 genera are described; 44 species are newly described; the stratigraphic and geographical ranges of the majority of taxa are improved considerably.  相似文献

Well-preserved palynomorph assemblages are recovered from the Devonian Jauf and Jubah formations in five shallow boreholes in the northern part of Saudi Arabia. These fully cored boreholes overlap stratigraphically to form a 1640 ft composite sequence. Miospores dominate the palynological assemblages of most samples. The assemblages are mainly composed of trilete spores but also contain cryptospores and monolete spores. One new genus, sixteen new species and two new varieties of miospores are described from the studied assemblages: Artemopyrainconspicua nov. sp., Artemopyrarecticosta nov. sp., Camarozonotriletesfilatoffii nov. sp., Camarozonotriletesrugulosus nov. sp., Cymbohilatesbaqaensis nov. sp., Cymbohilatescomptulus nov. sp., Cymbohilatesheteroverrucosus nov. sp., Cymbosporitesasymmetricus nov. sp., Dibolisporitespilatus nov. sp., Dictyotriletesbiornatus nov. sp., Gneudnasporadivellomedia (Chibrikova) Balme, 1988 var. divellomedia, Gneudnasporadivellomedia (Chibrikova) Balme, 1988 var. minor nov. var., Latosporitesovalis nov. sp., Scylasporacostulosa nov. sp., Squamisporaarabica nov. gen. and sp., Stellatisporamulticostata nov. sp., Zonotriletesarmillatus nov. sp. and Zonotriletessimplicissimus nov. sp. Their stratigraphic distribution is compared to the well-established Devonian West European zonation of Streel et al. (1987) (Streel, M., Higgs, K.T., Loboziak, S., Riegel, W., Steemans, P., 1987. Spore stratigraphy and correlation with faunas and floras in the type marine Devonian of the Ardenne-Rhenish region. Review of Palaeobotany and Palynology 50, 211-219). A late Pragian-Givetian age is suggested for this sequence. No characteristic Eifelian taxa are recorded, but this could be explained by a gap in palyniferous samples.  相似文献

The present paper describes 12 species of fish otoliths recovered by washing and screening processes from the Deccan Trap associated sedimentary (Intertrappean) beds exposed near Rangapur, Hyderabad District, Andhra Pradesh, India. The present collection of otoliths contains four major groups: Clupeomorpha (“Clupeidarum” sp.), Osteoglossomorpha (“Osteoglossidarum” deccanensis sp. nov., “O”. intertrappus sp. nov. and “Notopteridarum” nolfi sp. nov.), Protacanthopterygii (“Salmoniformorum” rectangulus sp. nov.), and Percomorpha (Dapalis sp., “Apigonidarum” ovatus sp. nov., “Serranidarum” sp., “Percoideorum” ellipticus sp. nov., “P.” rangapurensis sp. nov., “Percoideorum” sp. 1 and “Percoideorum” sp. 2). This collection of otoliths represents freshwater lacustrine deposition of the sediments. The age of the Intertrappean beds is considered Uppermost Cretaceous to Palaeoncene on the basis of freshwater ostracode (Paracypretta jonesi, Mongolianella hislopi and Candoniella sp.) and charophyte (Platychara perlata and Nemegtichara sp.) assemblages.  相似文献

The new species Protorhyphus rohdendorfi sp. nov. (Protorhyphidae), Mesorhyphus handlirschi sp. nov., and M. hennigi sp. nov. (Anisopodidae), Procramptonomyia ponomarenkoi sp. nov. and P. kovalevi sp. nov. (Procramptonomyiidae) are described from the Upper Jurassic deposits of Mongolia (Shar Teg); some features of Archirhyphus asiaticus Rohdendorf, 1964 are revealed. The latter two species are also known from the locality of Karatau (Kazakhstan, J2/3). The genus Tega Blagoderov, Krzemi??ska, and Krzemi??ski, 1993 is transferred from the family Cramptonomyiidae into Anisopodidae (Teginae subfam. nov.).  相似文献
