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 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

A new family of aphids, the Isolitaphidae fam. nov. (Hemiptera: Aphidoidea), is described for the new genus and species, Isolitaphis prolatantennus gen. et sp nov., in mid-Cretaceous amber from Myanmar (Burma). The new species is compared with previously described Mesozoic Aphidoidea, including members of the families Parvaverrucosidae and Burmitaphididae that were described earlier from Myanmar amber. The new taxon can be separated from all previously described extant and extinct Aphidoidea by its 10-segmented antenna, the presence of an ovipositor, siphons, a three-branched M vein and forked C vein. The new species adds to the morphological diversity of Mesozoic Aphidoidea.  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

A new genus and species of aphids, Tanyaulus caudisetula gen. et sp. nov. (Hemiptera: Aphidoidea: Burmitaphidae), is described from mid- Cretaceous Myanmar amber. Autapomorphies for the new genus are stub-like hind wings, 7-segmented antenna, long rostrum equal to body length, 4 veins departing from the main vein, cubital veins distinctly separated, with a very short, curved basal proximal cubitus, one-branched M vein with distal fork arched at the base, distinct claval folds at wing bases and caudal protuberance with extended setae. The new fossil adds to our knowledge of the morphological diversity of Mesozoic Aphidoidea.  相似文献

Annulipsyllipsocus andreneli gen. et sp. nov. and A. inexspectatus gen. et sp. nov., the first records of the Psyllipsocidae from the Cretaceous amber of Myanmar are described, illustrated and their taxonomic position discussed. The new genus is characterized by antennae with 16 segments; flagellomeres with secondary annulations; radial cell closed, five-angled, bulged on its R1 border; triangular pterostigma. Species belonging to Annulipsyllipsocus gen. nov. are polymorphic. The described taxa represent the earliest evidence for polymorphism in Psocodea. A checklist of all known species of Psyllipsocidae is given.  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

The fossil snakefly family Baissopteridae from the Lower Cretaceous (upper Barremian) of the Yixian Formation of Liaoning Province, China is reviewed. Two genera and five species of Baissopteridae are recorded, including a new genus, namely Microbaissoptera gen. nov., and three new species, i.e., Baissoptera bicolor sp. nov., Baissoptera sinica sp. nov., and Microbaissoptera monosticha sp. nov. Moreover, Baissoptera euneura Ren, 1997 is herein treated as a new junior synonymy of Baissoptera grandis Ren in Ren et al., 1995. Baissoptera minima Ponomarenko, 1993 is transferred to the presently described new genus Microbaissoptera gen. nov. based on the small body-size and the presence of a single gradate series of crossveins in radial and medial areas of posterior part of both fore- and hind wings. A key to genera of Baissopteridae is provided.  相似文献

A new subfamily, Burmadysagrioninae Zheng, Wang and Nel, subfam. nov., for the genus and species Burmadysagrion zhangi Zheng, Wang and Nel, gen. et sp. nov. is described from mid-Cretaceous Burmese amber. This is the third dysagrionid damselfly from the Mesozoic and the second one from Burmese amber. The new specimen has a unique discoidal cell with the anterior and posterior sides not parallel, and the basal side longer than the distal side, unlike the typical ‘sieblosiid-dysagrionine’ type. It differs from other dysagrionid damselflies by the presence of a simple wing venation, the vein IR1 originating below the pterostigma and a special discoidal cell.  相似文献

A third genus and species of fossil pygidicranid earwigs from Burmese amber is described and figured as Stonychopygia leptocerca Engel, Huang, Thomas, and Cai, gen. et sp. nov. (type species of Stonychopygia Engel and Huang, gen. nov.; Stonychopygiinae Engel and Huang, subfam. nov.). Stonychopygia have features similar to the subfamily Echinosomatinae such as the combination of shorter, subequal second and third flagellomeres and femora that are neither compressed or keeled. However, the new fossil species differs from echinosomatines in many details, particularly the slender form, head longer than wide, slender scape, slender and elongate forceps, and absence of stout, short bristles over the integument. The new fossil is compared with its contemporaneous and modern relatives, and comments are provided regarding the classification of Pygidicranoidea, with the genus Haplodiplatys Hincks removed from Diplatyidae to Haplodiplatyidae Engel, fam. nov.  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

Ostracod from the upper Lower to Middle Devonian rocks of the Argentine Precordillera Basin (Talacasto and Punta Negra formations) are studied. One new genus Pircawayra nov. gen., and five species (including three new: Pircawayra gigantea nov. gen. and sp., Lapazites trinodis nov. sp. and Keslingiella? teresae nov. sp.) are defined. The recorded ostracod fauna closely resembles that coeval from Bolivia and South Africa, exhibiting a remarkable endemism, not only at the genus level, but also at the species level. In addition to its low-diversity, the Malvinokaffric ostracod association is also characterized by having large, thick, coarsely ornamented and swollen valves. The similar ostracod composition from the Andean and South African basins suggests faunal exchange between these two areas. Based on the ostracod faunas, the Malvinokaffric Realm is clearly recognizable at least up to the Middle Devonian.  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

A new genus with two new species, Orentalphila gravia gen. et sp. nov. and O. caloa sp. nov., and three new species in two known genera, Sinosciophila angustia sp. nov., Sinosciophila seboa sp. nov. and Similsciophila undulata sp. nov., are described from the Lower Cretaceous of Yixian Formation at Huangbanjigou, Beipiao City, western Liaoning, China. These new taxa, representing the first records of mesosciophilids from this locality, provide morphological information and diversity for Mesosciophilidae in the Early Cretaceous. An updated key to known genera of Mesosciophilidae is provided. In addition, according the generic diagnosis revised by Zhang, 2007, Mesoplecia antiqua Hao and Ren, 2009 should be transferred to Mesosciophila Rohdendorf, 1946.  相似文献

Belemnites from the lower Bathonian of the Russian Plate are revised on the basis of the study of two reference sections—Pletnyovka and Sokur quarries. The first part of the study deals with the members of the family Megateuthididae. They include eight species of the genus Barskovisella gen. nov., neoendemic to the territory of the Russian Plate and originating from high Boreal taxa—species of the genus Paramegateuthis Gustomesov, 1960, which immigrated to the Middle Russian Sea in the early Bathonian via a short-lived meridional strait. The new genus includes six new species described in the present paper—Barskovisella pseudoishmensis sp. nov., B. issae sp. nov., B. variabilis sp. nov., B. barskovi sp. nov., B. gracilis sp. nov., and B. renegata sp. nov. The beds with Barskovisella, a new belemnite-based unit, corresponding to the Oraniceras besnosovi ammonite zone and including four successive phylogenetic biohorizons well comparable in resolution with ammonite-based infrazonal subdivisions, are introduced.  相似文献
