A new family of planthoppers Fulgoromorpha from the Lower Jurassic of southern China is described to comprise Qiyangiricania cesta Lin, 1986. The new family differs in venation pattern from the other Jurassic representatives of Fulgoroidea, presenting particular model of tegmen venation, not found among extinct and recent planthoppers. The Mesozoic stage of Fulgoroidea evolution is discussed. The extinct taxon Ricaniites fulgens (Brodie, 1845) from the Purbeck of United Kingdom is excluded from the Hemiptera. 相似文献

The family Mesopsychidae Tillyard,1917 presently consists of ten described genera from the Early Permian to the Early Cretaceous of Australia,China,Kyrgyzstan,Russia,South Africa,Tajikistan,and Ukraine.Herein,a new genus and a new species of fossil mesopsychid,Epicharmesopsyche pentavenulosa gen.et sp.nov.,is described from the Middle Jurassic Jiulongshan Formation of Inner Mongolia,China,supplementing the family-level diversity.The well-preserved,new material reveals many characters,including antennae,wing venation,shape and genitalia that increase our morphological understanding of the family,although unfortunately the mouthparts and most of the legs are not preserved.Diagnosis of the Mesopsychidae is emended to include a four-or five-branched MP in both the fore-and hind wings.This is the first documentation of a wing coupling structure in the Mesopsychidae,consisting of three to four frenula bristles on the humeral lobe at the base of the costal margin of both hind wings.Asymmetrical shape and size of the left and right wings on a specimen of E.pentavenulosa gen.et sp.nov.,seems to be a common condition for mesopsychid taxa from northeastern China. 相似文献

A New Species of the Family Juraperlidae(Insecta:Grylloblattida)from the Middle Jurassic of China 总被引：1，自引：1，他引：0
<正>Juraperla grandis sp.nov.(Grylloblattida:Juraperlidae) is described from the Daohugou locality (Middle Jurassic,China).Its wing venation is very similar to that of Juraperla daohugouensis Huang and Nel,2007 (Grylloblattida:Juraperlidae),in the particular occurrence of a supplementary longitudinal vein in the area between the anterior wing margin and ScP.The larger size of the new specimen,the lower number of CuA1 branches,and the occurrence of two rows of cells between MP and CuA in forewings justify the erection of a new species,J.grandis sp.nov..The material also preserved hind wing and body structures,described for the first time in Juraperlidae. 相似文献

A new genus with a new species, Sinohelorus elegans gen. et sp. nov., is described and assigned to the subfamily Mesohelorinae, Heloridae. In addition, two new species, Gurvanhelorus beipiaoensis sp. nov. and Spherogaster saltatrix sp. nov., are also described. The diagnoses of Gurvanhelorus Rasnitsyn, 1986 and Spherogaster Zhang and Zhang, 2001 are emended based on new materials and findings. These well-preserved specimens were collected from the Jehol Biota, Early Cretaceous Yixian Formation of Huangbanjigou Village in Liaoning, China. These new species broaden the diversity of this family and enhance our understanding of evolutionary trend of helorid’s metasomal structure, antenna, and forewing venation from the Middle Jurassic to extant. 相似文献

The first definitive Burmese amber fossil of the family Gasteruptiidae s.str. (Evanioidea) is described and figured from a male entombed in amber from the Hukawng Valley, Myanmar. The Cenomanian-aged fossil is plesiomorphic in many respects when compared to the modern subfamilies Hyptiogastrinae and Gasteruptiinae. The genus Hypselogastrion Engel, gen. nov. (type species: Hypselogastrion simplex Engel and Wang, sp. nov.), is segregated into the extinct subfamily Hypselogastriinae Engel, subfam. nov., owing the more enriched wing venation, aulcid-like mesoscutal sculpturing, non-clavate metatibia, and absence of U-shaped notauli. The affinities of H. simplex among other living and fossil Aulaciformes are discussed. 相似文献

Early Evolution of Apocrita(Insecta,Hymenoptera)as Indicated by New Findings in the Middle Jurassic of Daohugou,Northeast China 总被引：2，自引：1，他引：1
<正>The classification and phytogeny of the basal Vespina(=Orussoidea+Apocrita)are reconsidered based primarily on rich and well preserved material from the Middle Jurassic of Daohugou in Inner Mongolia,China. Comparatively smooth morphological transitions are traced from a Xiphydriidae-like ancestor toward Orussoidea via the Jurassic family Karatavitidae,and through Karatavitidae and the Jurassic and Early Cretaceous family Ephialtitidae independently to Stephanidae,to Evanioidea,and,via the extinct Jurassic Kuafuidae fam.nov.to the remaining Apocrita.New hypothesis is proposed concerning development of the characteristic wasp-waist of Apocrita,which is supposed to appear independently and in different ways in Evanioidea and in the rest of Apocrita.As a result,six infraorders are proposed for the suborder Vespina with the following taxonomic structure:infraorder Orussomorpha including the only superfamily Orussoidea(Karatavitidae+Paroryssidae + Orussidae),infraorder Stephanomorpha with the only superfamily Stephanoidea(Ephialtitidae+Stephanidae), infraorder Evaniomorpha with the only superfamily Evanioidea of traditional composition,infraorder Ceraphronomorpha with the superfamilies Ceraphronoidea s.str.and monotypical Megalyroidea and Trigonaloidea,and the infraorders Proctotrupomorpha,Ichneumonomorpha,and Vespomorpha of traditional composition.The family Kuafuidae is unplaced to infraorder because it is putatively paraphyletic with respect to Ceraphronomorpha,Proctotrupomorpha,Ichneumonomorpha and Vespomorpha.Described as new are Karatavites junfengi sp.nov,Praeratavites wuhuaensis sp.nov.,P.perspicuus sp.nov.,Postxiphydria daohugouensis gen.et sp.nov.,P.ningchengensis gen.et sp.nov.,Postxiphydroides strenuus gen.et sp.nov.,Praeratavitoides amabilis gen.et sp.nov.,Proapocrtius densipediculus sp.nov.,P.sculptus sp.nov.,P.longantennatus sp.nov., P.formosus sp.nov.,P.atropus sp.nov.,P.elegans sp.nov.,Stephanogaster pristinus sp.nov.,Asiephialtites lini sp. nov.,Praeproapocritus vulgatus gen.et sp.nov.,Sinaulacogastrinus solidus gen.et sp.nov.,Sinevania speciosa gen. et sp.nov.,Eonevania robusta gen.et sp.nov.,Kuafua polyneura gen.et sp.nov.(all from the Middle Jurassic of Daohugou),as well as Kuafuidae fam.nov.including Kuafua gen.nov.as well as Arthrogaster Rasnitsyn,1975,and Leptogastrella Rasnitsyn,1975 from the Upper Jurassic of Karatau in Kazakhstan. 相似文献

Diverse caddis flies are recently collected from the Middle Jurassic Daohugou fauna in Ningcheng County, Inner Mongolia, northern China, and different types of caddis cases have been reported in the same locality. A new species of caddisfly, Liadotaulius daohugouensis sp. nov. is described and illustrated; the establishment is based on a well-preserved isolated forewing collected from the Middle Jurassic Jiulongshan Formation of Daohugou. The family status of Liadotaulius is discussed on the basis of new material and is referred to the family Philopotamidae. The Daohugou fauna continues to provide new data for studying the early evolution of Trichoptera. 相似文献

Jurodidae are thought to be some of the world's most mysterious beetles and display an intriguing mixture of characters occurring in three different suborders. Hitherto, all known fossil and extant Jurodidae were extremely rare and restricted to Russian Siberia and the Far East. Here we describe two new species, Jurodes daohugouensis sp. nov. and Jurodes pygmaeus sp. nov. from the Middle Jurassic of Daohugou, China. A key to all species of Jurodidae and their research history are given, and the detailed morphology of fossil Jurodidae is also presented. Our results confirm the presence of three ocelli in fossil Jurodidae, and reveal that hind wings of J. pygmaeus sp. nov. possess well developed radial and oblong cells, and are very similar to those of extant Jurodidae (Sikhotealinia zhiltzovae). Male genitalia of fossil Jurodidae were described herein for the first time, showing a basal trilobate structure. The presence of exposed propleuron, three pairs of external trochantins, metanepisterna with ridges, primitive characters of wing venation further support the probable placement of Jurodidae in the suborder Archostemata. J. daohugouensis and J. pygmaeus are very similar to S. zhiltzovae in having the big protruding eyes, elevated median portion of frons bearing three ocelli, pubescent body, contiguous procoxae, exposed trachantion of all coxae, elytra with rows of punctures, and wing venation. Our results show that these key characters of extant Jurodidae can be traced back to the Middle Jurassic, revealing that the family has been in a period of evolutionary stasis for at least 160 million years. Furthermore, our discoveries widen the paleogeographic distribution of fossil Jurodidae from Russian Siberia to northern China. 相似文献

Although recent molecular phylogenetic analyses suggest a great antiquity, going into the Jurassic, for the small modern fly family Hilarimorphidae, no fossil was attributed to this group. The first fossil hilarimorphid Cretahilarimorpha lebanensis gen. et sp. nov., is described, based on a specimen from the Lower Cretaceous Lebanese amber. Its external morphology is analysed and compared with that of Hilarimorpha, unique modern hilarimorphid genus. The differences concern the wing venation, antenna and especially mouthparts. Cretahilarimorpha has very elongate mouthparts, adapted for nectar feeding or (less probably) for predation on other insects. Several other Lower Cretaceous lineages have developed similar elongate mouthparts, viz. nemestrinid and xylomyiid flies, and the Mecoptera: Aneuretopsychina, probably adapted to still unknown deep nectar-producing flowers. A checklist of species belonging to the Hilamorphidae is given. 相似文献

Prophaenognatha robusta gen. et sp. nov. (Scarabaeoidea: Scarabaeidae: Aclopinae), the best-preserved aclopine fossil so far, is described and illustrated from the Upper Jurassic–Lower Cretaceous Yixian Formation of the Jehol Biota, western Liaoning Province, NE China. The key to extinct and extant genera of Aclopinae is given and the monophyly of extant and fossil Aclopinae lineages is supported by five character states. The new taxon provides evidence about the evolution of Scarabaeoidea with its phylogenetic position inferred based on 68 morphological characters. 相似文献

Lower Cretaceous beetles belonging to the extinct tribe Brochocoleini (Coleoptera: Cupedidae: Ommatinae) are revised and five new species proposed in the extinct Eurasian genus Brochocoleus: Brochocoleus yangshuwanziensis sp. nov. (Yixian Formation, China); Brochocoleus crowsonae sp. nov., Brochocoleus keenani sp. nov., Brochocoleus tobini sp. nov. (Weald Clay Group, UK); and Brochocoleus maximus sp. nov. (Purbeck Limestone Group, UK). New morphological data is provided for Brochocoleus impressus and Brochocoleus sulcatus stat. nov. of which Brochocoleus angustus is considered a synonym (Yixian Fm.). The hindwing venation is described for the first time supporting the basal position of this tribe. A simple key is provided to all Cretaceous species of this presumably xylophagous, warm climate genus. 相似文献

A new family of thrips, Moundthripidae, is described on the basis of a new genus and species, Moundthrips beatificus, from Early Cretaceous Lebanese amber. This taxon has plesiomorphic prognathous mouthparts, a unique type of wing venation and the main apomorphies of the Thysanoptera of the legs and mouthpart structures, suggesting that they were acquired very early during the evolution of this order. 相似文献

A New Cockroach Genus of the Family Fuziidae from Northeastern China (Insecta: Blattida) 总被引：1，自引：0，他引：1
A new genus and two new species of fossil Fuziidae are described and illustrated: Parvifuzia gen. nov., P. marsa sp. nov. and P. brava sp. nov.. Both species were collected from the Middle Jurassic Jiulongshan, Formation of Daohugou, Inner Mongolia of China. In conjunction with Fuzia Vr?ansky, Liang et Ren, 2009, the present findings allow us to demonstrate that members of the family were morphologically diverse, with body length ranging from medium (17 mm) in Fuzia to small (9.7 mm) in the present genus. Wing venation of F. dadao is complicated, but simple in the present species, and apex of male’s cerci are sharp and forceps-like in F. dadao, but strongly curved inward and round in the new genus. 相似文献

Since Holcorpa maculosa was first described in 1878, it has attracted lots of attention due to its extremely elongate abdominal segments from the sixth to the eighth. Fossil records of family Holcorpidae are very rare, comprising two species in one genus represented by three fossil specimens, resulting in limited knowledge on the structure and function of holcorpid’s unique male organ, as well as its evolutionary relationship with other scorpionflies. Herein we describe a new genus with a new species, Conicholcorpa stigmosa gen. et sp. nov., of the Holcorpidae from the Middle Jurassic Jiulongshan Formation near Daohugou Village, Inner Mongolia, China. This is the first holcorpid documented from the Daohugou locality, albeit two previously reported species with extremely elongate male organs but deemed as Family Incertae sedis. C. stigmosa gen. et sp. nov. is the earliest holcorpid hitherto, extending its existence from the Early Eocene to the Middle Jurassic by 114 million years and providing one more early case of presenting exaggerated male body parts for sexual display and/or selection. Our analysis supports the sister relationship between Holcorpidae and Orthophlebiidae. Our results not only enhance our knowledge of the morphology of Holcorpidae but also elucidate the relationship of known species of this family. 相似文献

<正>The present paper is devoted to an overview on fossil Coleoptera studied from Inner Mongolia, Daohugou(Middle Jurassic,Jiulongshan Formation)and Liaoning(Upper Jurassic-Lower Cretaceous,Yixian Formation)deposited in Chinese collections.As a result,species of the tribe Sperchopsini and Hydrophilini from Hydrophilidae,families and subfamilies Silphidae,Syndesinae from Lucanidae,Pleocomidae,Trogidae, Trogissitidae,Pyrochroidae,Diaperinae from Tenebrionidae,and Cerambycidae were first registered in the Mesozoic and some families were defined as new.It was shown that many superfamilies represented in the Recent Fauna were formed within the Middle Jurassic and Lower Cretaceous.The materials examined confirm the hypothesis that Cucujiformian beetles are a younger group than other infraordera of Polyphaga(Staphyliniformia and Elateriformia)and,therefore,they appeared in the fossil record only in the late Mesozoic.It was shown and confirmed that most superfamilies appeared in the fossil records before Cucujoidea.The synonymy of Notocupes Ponomarenko,1964;Sinocupes Lin,1976,syn.nov.;Amblomma Tan,Ren et Liu 2005,syn.nov.;Euryomma Tan, Ren et Shih,2006,syn.nov.,non Stein,1899 and Ovatocupes Tan et Ren,2006,syn.nov.;synonymy of Tetraphalerus Waterhouse,1901 and Odontomma Tan,Ren et Ge 2006,syn.nov.;and synonymy of Priacmopsis Ponomarenko,1966 and Latocupes Tan et Ren,2006,syn.nov.are proposed.Sinorhombocoleus papposus Tan et Ren,2009 is transferred from the family Rhombocoleidae to Schizophoridae.Cervicatinius complanus Tan,Ren et Shih,2007 and Forticatinius elegans Tan,Ren et Shih,2007 are transferred from the family Catiniidae(suborder Archostemata)to superfamily Cleroidea(suborder Polyphaga:first among the family Peltidae and second as a closely related group to the latter family).The family Parandrexidae is transferred from the superfamily Cucujoidea to Cleroidea.The ecological circumstances of the past ecosystems and hypotheses of historical development of the order Coleoptera are discussed.The age of faunas examined is considered.The list of the taxa described from Daohugou and Liaoning is compiled. 相似文献

The relatively rare Late Jurassic plant Pachypteris has been found in some abundance in Batskian and Callovian deposits in the Gissar Range, U.S.S.R. Previously unknown morphological and anatomical details are observable in this material. The fronds are bipinnate with dichotomous rachises; the pinnules vary in size, and in margination from entire to crenulate or denticulate. The venation is odontopteroid and the stomata are haplocheilic. Pachypteris is held to be an index of not only Jurassic age but also of deltaic or littoral deposits.--S. H. Mamay. 相似文献
