<正>One new genus and five new species of the family Evaniidae are described from the Early Cretaceous (Albian)Spanish amber of Penacerrada-Ⅰ(Province of Burgos),San Just and Arroyo de la Pascueta(both in the Province of Teruel):Cretevania alonsoi sp.nov.,C.montoyai sp.nov.,C.alcalai sp.nov.,C.rubusensis sp.nov.,and Iberoevania roblesi gen.and sp.nov.Taxonomic changes include Cretevania pristina(Zhang and Zhang,2000) comb.nov.,C.exquisita(Zhang,Rasmtsyn,Wang and Zhang,2007)comb.nov.,C.vesca(Zhang,Rasnitsyn,Wang and Zhang,2007)comb.nov.,and C.cyrtocerca(Deans,2004)comb.nov.,as a result of the reinterpretation of the genera Procretevania and Eovernevania.The new well preserved specimens of the genus Cretevania,together with the characters shown by the type specimens of the synonymized genera,give new information about their anatomical characters of taxonomical importance,and the genus Cretevania Rasnitsyn,1975 is re-diagnosed.The holotypes of the Russian species in amber have been revised.A cladistic analysis of fossil and extant groups of the superfamily Evanioidea is included.Cretevania had a wide palaeogeographic distribution,with the highest diversity known from Spain.The 13 known Cretevania species show a high interspecific variation mainly in wing characteristics,and a wide range of body and wing size. 相似文献

Three new species of Dermestidae are described and illustrated from the Upper Cretaceous Burmese amber: Attagenus secundus sp. nov. (Attageninae: Attagenini), Cretodermestes palpalis gen. et sp. nov. (Attageninae: Cretodermestini trib. nov.) and Megatoma atypica sp. nov. (Megatominae: Megatomini). Members of Dermestidae are relatively frequent in Burmese amber, representing at least three subfamilies: Attageninae, Dermestinae and Megatominae. Taxonomic and morphological diversity of Cretaceous Dermestidae suggests ancient origin of this group with some lineages showing remarkable evolutionary stasis for almost 100 million years. 相似文献

A new genus with a new species, Brachypelecinus euthyntus gen. et sp. nov., and two new species, Abropelecinus tytthus sp. nov. and Zoropelecinus periosus sp. nov., are described and figured from three exquisitely preserved pelecinid wasps in the Upper Cretaceous Myanmar (Burma) amber. These taxa, owing to their well-preserved characters in amber, provide a better understanding of morphological changes and relationships among the constituent groups, while further highlighting the diversity of Pelecinidae in the Mesozoic. 相似文献

The lower part of the Pawpaw Shale in northeast Texas yields an abundance of diminutive limonitic ammonites, the assemblage being: Tetragonites sp. juv., Engonoceras serpentinum (Cragin, 1900), Conlinites wrighti gen. et sp. nov., Cantabrigites wenoensis (Adkins, 1920), Neophlycticeras (Neophlycticeras) sp., Neophlycticeras (Paradolphia) occidentalis sp. nov., Stoliczkaia (Stoliczkaia) clavigera Neumayr, 1875, Stoliczkaia (Lamnayella) worthense (Adkins, 1920), Stoliczkaia (Shumarinaia) asiatica Matsumoto and Inoma, 1975, Enigmaticeras riceae gen. et sp. nov., Flickia simplex Pervinquière, 1907, Ficheuria pernoni Dubourdieu, 1953, Ficheuria americana sp. nov., Anisoceras armatum (J. Sowerby, 1817), Hamites venetzianus Pictet, 1847, Mariella (Mariella) worthensis (Adkins and Winton, 1920), Mariella (Mariella) asper sp. nov., Lechites (Lechites) comanchensis (Adkins, 1920), Worthoceras worthense (Adkins, 1920), and Scaphites hilli Adkins and Winton, 1920.This assemblage is correlated with the Mortoniceras (Subschloenbachia) rostratum Subzone of the European sequence on the basis of the occurrence of that species in the underlying Weno Limestone, in the passage beds between the Pawpaw Shale and the succeeding Main Street Limestone, and the lower part of the Main Street.Some previous authors have interpreted the diminutive limonitic ammonites of the Pawpaw as being “dwarf” or “stunted”. The overwhelming majority of individuals are nuclei of much larger ammonites, with smaller numbers of adults of small species that occur in other facies and geographic locations, together with a smaller number still of paedomorphic dwarfs. The fauna is interpreted as a preservational one, where diagenetic pyrite formed in relatively small voids, either the early phragmocone chambers of larger ammonites, or the phragmocone and body chambers of genuinely diminutive species which oxidised to limonite during the weathering process. 相似文献

The biodiversity record of graptolites from the Cheeseman's Creek Formation, considered herein as late Gisbornian (Caradoc) in age, has been substantially increased to fifteen taxa, including the new species Dicellograptus praemorrisi sp. nov. and Climacograptus vandenbergi sp. nov. Some of the records have global correlative significance enabling us to identify the wilsoni Biozone ( = calcaratus Biozone of eastern Australia). Several evolutionary lineages have been recognized:
- 1 Dicellograptus moffatensis (Carruthers, 1858) → D. praemorrisi sp. nov → D. morrisi Hopkinson, 1871
- 2 Glossograptus hincksi Hopkinson, 1872 → Glossograptus? sp.
- 3 Climacograptus bicornis (J. Hall, 1847) → C. vandenbergi sp. nov. → C. lanceolatus VandenBerg, 1990.

In this paper one new genus and three new species Bellimordella capitulifera gen. et sp. nov., B. longispina gen. et sp. nov., B. robusta gen. et sp. nov., all placed within the subfamily Praemordellinae of the family Mordellidae, are described and illustrated. The specimens were recovered from the Yixian Formation of Beipiao City, Liaoning Province, NE China. The key to the species of this new genus is given. Furthermore, we discuss evolution of the pygidium and possible food for those ancient mordellids. 相似文献

Seven specimens of fossil scorpionflies (Mecoptera) not assignable to any known family were discovered in the Wealden Supergroup (Lower Cretaceous) of southern England. They were found at Rudgwick Brickworks, West Sussex and Smokejacks Brickworks, Surrey and came from the Upper Weald Clay Formation, dated as Barremian (∼129.4–125 Ma). A new family – Englathaumatidae fam. nov., new genus – Englathauma gen. nov. and two new species E. crabbi sp. nov. and E. mellishae sp. nov. are described. A discussion of systematic position of these new taxa within the order Mecoptera is given. Englathaumatidae fam. nov. has been a nomen nudum since the year 2002, due to the first author's untimely death. 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

Four new, monotypic genera of Aleyrodidae from the Lower Cretaceous Lebanese amber are described: Shapashe aithiopa gen. sp. nov.; Milqartis azari gen. sp. nov.; Aretsaya therina gen. sp. nov.; and Yamis libanotos gen. sp. nov. All new taxa represent subfamily Aleurodicinae. The key for identification of genera of Aleurodicinae from the Lebanese amber is provided. The morphological features of newly established taxa are discussed. The importance of the fossils for phylogenetic, evolutionary and ecological studies is presented. 相似文献

One new genus with three new species of the family Prionoglarididae, Palaeosiamoglaris leinhardi Azar, Huang et Nel gen. et sp. nov.; P. burmica Azar, Huang et Nel sp. nov. and P. inexpectata Azar, Huang et Nel sp. nov. are characterised, illustrated and described from Cretaceous Burmese amber. Palaeosiamoglaris gen. nov. share several characters with the recent genus Siamoglaris Lienhard, 2004, endemic to the Oriental (Sino-Indian) Region. A new tribe Siamoglaridini Azar, Huang et Nel trib. nov. is established to accommodate the group Siamoglaris + Palaeosiamoglaris; the other Prionoglaridinae being attributed to Prionoglaridini. This discovery implicates a palaeobiogeographic repartition for this particular tribe (Siamoglarini) that is still the same currently. Most diagnostic features show a nearly stasis state, supporting the notion that these characters appeared at least by the early Cenomanian. A checklist of all prionoglaridids is given. 相似文献

Two new genera from the Lower Cretaceous Yixian Formation of Beipiao City, Liaoning Province, northeastern China are described and illustrated. Paracretocateres gen. nov. (type species P. bellus, sp. nov.) and Yixianteres gen. nov. (type species Y. beipiaoensis sp. nov.) are assigned to the subfamily Lophocaterinae based on the state of the procoxae which are not projecting, the transverse procoxal cavities, and the exposed protochantins. The new taxa broaden the diversity of this family and provide further morphological characters for phylogenetic studies of Trogossitidae. They also provide evidence that lophocaterines well-diversified prior to the trogossitines and their biologies may have been similar to extant forms. 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 diverse fauna of wasps of the extinct parasitoid family Stigmaphronidae (Ceraphronoidea) are recorded in Early Cretaceous (Lower Albian) amber from Spain. Seven new species in five genera are described and figured based on 51 specimens, representing more material than in all the world’s other amber deposits combined. New species include: Elasmophron mari sp. nov., Libanophron sugaar sp. nov., Hippocoon basajauni sp. nov., Burmaphron jentilak sp. nov., B. sorginak sp. nov., B. iratxoak sp. nov., and Tagsmiphron olentzero sp. nov. The significance of the fauna is discussed and compared with that of other Cretaceous amber deposits, in particular the tremendous richness of the Spanish fauna is contrasted with the complete absence of stigmaphronids in the slightly younger and nearby French amber. Whether this stark difference represents particularly favorable conditions for these parasitoids, or their hosts, in the Cretaceous Spanish archipelago, or whether it is owing to taphonomic factors is discussed. 相似文献

Three new species within the stigmaphronid genus TagsmiphronEngel and Grimaldi, 2009, and one new species within the megaspilid genus ConostigmusDahlbom, 1858 are described from Upper Cretaceous (Campanian) amber originating at the Grassy Lake locality in Alberta, Canada. New taxa include Tagsmiphron spiculum sp. nov., Tagsmiphron leucki sp. nov., Tagsmiphron exitorum sp. nov., and Conostigmus cavannus sp. nov. The new Conostigmus species is a rare discovery. It is the third megaspilid species to be found in Cretaceous amber, with the two specimens described herein effectively doubling the number of known Mesozoic exemplars for the family. We provide the first comprehensive report of known Ceraphronoidea within Canadian amber, and contrast this against other Cretaceous amber assemblages, discussing the potential palaeobiogeographic and palaeoenvironmental implications of the Canadian amber assemblage. 相似文献

A new subfamily of Ichneumonidae, Novichneumoninae subfam. nov., is established based on two new genera with two new species: Novichneumon longus gen. et sp. nov. and Caloichneumon perrarus gen. et sp. nov. These two new species are the first ichneumonids described from the Upper Cretaceous Myanmar (Burmese) amber. A list of all described Mesozoic ichneumonid fossil species with their respective localities and ages is summarized. The distribution of Ichneumonoidea during the Cretaceous indicates that Cretaceous ichneumonids were documented from localities at high latitudes while braconids were distributed worldwide, a pattern consistent with the distribution of extant ichneumonids and braconids. 相似文献
