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

New Mesozoic Mesopsychidae(Mecoptera)from Northeastern China 总被引：2，自引：2，他引：0
<正>The Mesozoic family Mesopsychidae Tillyard,1917 presently consists of seven described genera and 13 species from the mid-Triassic to the Early Cretaceous of Australia,South Africa and Eurasia.In the present paper one new genus and three new species of fossil mesopsychids are described that add significant distributional and stratigraphic extensions to the family.This finding documents the first formal record of fossil Mesopsychidae in China.Both Lichnomesopsyche gloriae gen.et sp.nov.and L.daohugouensis gen.et sp.nov. were found from the Middle Jurassic Jiulongshan Formation of Inner Mongolia,whereas Vitimopsyche kozlovi sp. nov.,of mid Early Cretaceous age,was collected from the Jehol Biota of northern Hebei Province.This new,well-preserved material from China reveals complete and previously unknown body features,including head, antennae,mouthparts,legs and abdomen.The delicate and long proboscides of these new taxa indicate that they were feeding on externally exposed,nutrient-rich fluids of gymnospermous ovulate fructifications,and incapable of piercing surface epidermis-attributable principally to the absence of stylets.These proboscides originated, perhaps multiply,among basal Mecoptera and are functionally and structurally convergent with equivalent mouthparts borne by fossil and extant Diptera,Lepidoptera,Neuroptera and Coleoptera. 相似文献

New lacewings (Insecta: Neuroptera) from the Lower Cretaceous Wealden supergroup of Southern England
James E. Jepson Vladimir N. Makarkin Edmund A. Jarzembowski 《Cretaceous Research》2009,30(5):1325-1338
Eight new genera and thirteen new species of lacewings (Neuroptera) are described from the Lower Cretaceous Wealden Supergroup, Weald Sub-basin: Principiala rudgwickensis sp. nov. (Ithonidae), Stenomylina medialis gen. et sp. nov., Protosmylina bifasciata gen. et sp. nov. (Osmylidae), Cretapsychops corami gen. et sp. nov., Micropsychops parallelus gen. et sp. nov., Valdipsychops logunovi gen. et sp. nov., V. brigidae gen. et sp. nov., V. maculosus gen. et sp. nov., V. proudlovei gen. et sp. nov., V. minimus gen. et sp. nov., Psychopsites rolandi gen. et sp. nov. (Psychopsidae), Actinophlebioides valdensis gen. et sp. nov. and Protohemerobius perexiguus gen. et sp. nov. (Neuroptera familia incertae sedis). Psychopsidae are shown to dominate the neuropteran fauna, while the presence of Brongniartiellidae has not been confirmed in the Wealden, due to previously thought representatives of this family being in fact psychopsids. This is the first fossil record of Ithonidae and Osmylidae in Britain. The range of Kalligrammatidae has been extended in the Cretaceous of Britain from the mid-Valanginian to early Barremian. 相似文献

The lacewing family Babinskaiidae (Neuroptera: Myrmeleontoidea) is first reported in mid-Cretaceous amber from Myanmar. Two new genera and three new species are herein described, namely Babinskaia martinsnetoi sp. nov., Burmobabinskaia tenuis gen. et sp. nov., and Electrobabinskaia burmana gen. et sp. nov. The male and female genitalia of Babinskaiidae are described for the first time, and the genital morphology is compared with that of some related families in Myrmeleontoidea, e.g., Nymphidae and Nemopteridae. A brief discussion on the phylogenetic status of Babinskaiidae is given. 相似文献

Three new genera and two new species, namely Burmodipteromantispa jiaxiaoae gen. et sp. nov., Mantispidipterella longissima gen. et sp. nov., and Jersimantispa gen. nov., respectively from the Cretaceous amber of Myanmar and New Jersey, are herein described in the lacewing family Dipteromantispidae, which is an enigmatic group by the mantispid-like appearance combined with strongly reduced, haltere-like hind wings. The male genitalia of Dipteromantispidae is described for the first time and provides new insight for understanding the familial phylogenetic position. A key to the dipteromantispid genera is also given. 相似文献

Two new genera and three new species of the Mesozoic family Aeotheogrammatidae are described from the Lower Cretaceous of Yixian Formation (Liaoning Province, China): Cyclicogramma rotundum gen. et sp. nov. and Aetheogramma bistriatum sp. nov. from Huangbanjigou, and Curtogramma ovatum gen. et sp. nov. from Dawangzhangzi. The hind wing of Cyclicogramma rotundum gen. et sp. nov. differs from that of other species by its smaller size, its overall shape, RP bearing only two oblique radial branches, and its configurations of CuP, AA1, and AA2. Aetheogramma bistriatum sp. nov. is closely related to A. speciosum Ren and Engel, 2008, but distinguished from the latter by its distinctive configuration of RP1, and the narrower and longer AA2 space in the hind wing. Curtogramma ovatum gen. et sp. nov. is distinguished from all other species of the family by the forewing with M forking very far from the wing base. 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

Sclerogibbid wasps are obligate parasitoids of webspinners (Embiodea). Both groups have a particularly scarce geological record and are known since the Cretaceous: there are only four species of webspinners known from Burmese amber, and only two sclerogibbids were described from Barremian Lebanese and Cenomanian Burmese ambers. Here we report transferred genus from Aptian Choshi (Japan) amber and new sclerogibbids from Cenomanian Burmese and Charentese (France) ambers. The taxa described from Burmese amber are: Burmasclerogibba aptera gen. et sp. nov., Cretosclerogibba gen. nov. (with C. antennalis sp. nov., C. contractocollis sp. nov., C. neli sp. nov. and C. rasnitsyni sp. nov.) and Edrossia vetusta gen. et sp. nov. The first European fossil sclerogibbid Gallosclerogibba alnensis gen. et sp. nov. is described from Charentese amber. The holotype of Chosia yamadai Fujiyama, from Choshi amber, is re-described; it appears to be the oldest Laurasian sclerogibbid. The significant abundance and variety of Burmese sclerogibbid wasps (60% of fossil species known worldwide), as proxy of their hosts, were probably caused by the protection granted to them by the silk webs and possibly by the limited predation from ornithuromorph birds or crown-group ants. While all three extant sclerogibbid genera have apterous females, genera with winged females (Cretosclerogibba and Edrossia) dominated in Burmese amber. Small silk galleries from hosts may have favored the preservation of wings in females of Cretaceous sclerogibbids. Most new species described in the present paper, in addition to C. yamadai, are characterized by a very slender neck and a very long frontal process concealing the antennal toruli. These characters disappeared in extant species. We suggest that this loss was caused by a change in the fauna of predators, penalizing species with long neck and rostrum. 相似文献
