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

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

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

Cretocrenis burmanicus, gen. et sp. nov. is described from Burmese amber and represents the oldest known amber inclusion of the family Hydrophilidae (Coleoptera: Polyphaga). The new genus resembles the small-bodied modern genera of the tribe Anacaenini and the subfamily Acidocerinae, and the morphology of the venter and male genitalia suggest that it belongs to the Horelophus+Crenitis clade of the tribe Anacaenini. The fossil is described in detail, illustrated, and compared with extant hydrophilid genera. 相似文献

A new genus and species of Scoliidae (Hymenoptera), Sinoproscolia yangshuwanziensis gen. et sp. nov., is described from the Lower Cretaceous Yixian Formation in Inner Mongolia, China and attributed to the subfamily Proscoliinae. Some characteristics, including complete crossveins 1r-rs and 2r-m in the forewing, and a free section present in almost all longitudinal veins indicate a basal position of the new genus in Proscoliinae. The presence of vein 2A suggests its atavistic origin in Sinoproscolia gen. nov. rather than a true plesiomorphy. 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

A new genus and species, Gracilipygia canaliculata gen. et sp. nov., in the family Pygidicranidae of Dermaptera is described from the Upper Cretaceous Myanmar amber. The new species is assigned to the subfamily Pyragrinae mainly based on the following characters: broadly separated cercal forceps without segmentation and the posterior abdominal tergum with mediolongitudinal furrow and lateral ridges. The G. canaliculata gen. et sp. nov. is the earliest record hitherto for the subfamily Pyragrinae, and probably represents a stem taxa of Pyragrinae. 相似文献

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

A new species, Shoushida infera sp. nov. and a new genus with a new species, Stelepelecinus longus gen. et sp. nov., both in Pelecinidae, are described and illustrated. All specimens were collected from the Lower Cretaceous of Yixian Formation, Jehol Biota at Huangbanjigou, Beipiao City, western Liaoning Province, China. The forewing of Shoushida infera sp. nov. has a rudimentary “X” pattern, formed by veins of Rs, Rs1, Rs2 and 2r-rs, which is similar to but slightly different from that of Shoushida regilla Liu, Shih et Ren, 2009. Consistent with the phylogeny of Pelecinidae reported by Shih et al., 2010, this new species and S. regilla represent a transition between basal and crown pelecinids and the rudimentary “X” pattern evolved later to a more developed and robust “X” pattern in more derived pelecinids. In addition, the long petiole of the basalmost segment of metasoma, present in the male Stelepelecinus longus gen. et sp. nov., is documented for the first time, suggesting a likely Early Cretaceous origination of metasomal evolution leading to the thin and long petiole structure in the extant male Pelecinus thoracicus. We proposed two probable pathways of the transformation of the pelecinid male metasoma from the most plesiomorphic state to the more apomorphic states. 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

Two new peculiar mid-Cretaceous braconid genera, Megalyrhyssalus gen. nov. (type species Megalyrhyssalus clavicornis sp. nov.) and Stephanorhyssalus gen. nov. (type species Stephanorhyssalus longiscapus sp. nov.), are described and illustrated from Burmese amber. According to the particular morphology and wing venation of Megalyrhyssalus gen. nov. a new subfamily Megalyrhyssalinae subfam. nov. is created. The subfamily Seneciobraconinae is synonymised under Protorhyssalinae (syn. nov.). Additionally, a key to the genera of Braconidae having second recurrent vein (2m-cu) in forewing is provided. 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

A new genus and species of female phantom midge Neuseptychoptera carolinensis gen. et sp. nov. in the fossil subfamily Eoptychopterinae is described and illustrated; this ptychopterid is from Upper Cretaceous (Campanian) amber of North Carolina. This is the first member of Eoptychopterinae from North America and the first found in Campanian age amber. We propose to treat the extinct subfamily Eoptychopterininae Lukashevich, 1995, as a junior synonym of the subfamily Eoptychopterinae Handlirsch, 1906, syn. nov. The elongated mouthparts of the new species have broad labella, and these are functionally interpreted as feeders for honeydew, fermenting plant juices, and nectar rather than for biting. 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

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

Two new genera with two new species in Berothidae, Maculaberotha nervosa gen. et sp. nov. and Magniberotha recurrens gen. et sp. nov., are described from Upper Cretaceous Myanmar (Burmese) amber. Based on the new specimens of the same species, we propose some venational characters as intraspecific variations, e.g., the markings on the wings and crossveins in the radial sector. We also study and compare the female genital sclerites from three genera of Haploberotha, Dasyberotha, and Jersiberotha to highlight the importance of using these characters preserved in amber for taxonomic and phylogenetic studies. Furthermore, an updated key to the berothid genera of Myanmar amber is provided. 相似文献
