花蚤科Mordellidae隶属昆虫纲Insecta鞘翅目Coleoptera,是一类小型甲虫。花蚤为世界性分布,全世界已知115属2308种。花蚤成虫多栖息于花中,是植物传花授粉的重要媒介;其幼虫多取食植物茎秆,是常见的农业害虫。因此,对其开展系统学研究,进行准确的种类鉴定对于农林业生产具有重要意义。目前世界范围内已开展的花蚤科研究均为区域性工作,相对其它动物地理区而言,东洋区尚有大量的种类有待发现和描述,同时也缺少全面的区系研究和系统的分类修订工作。另外,花蚤科是鞘翅目昆虫系统树上的关键节点之一,对其进行深入的形态、分子研究,重建其系统发育以修订完善鞘翅目高级阶元分类系统,也将对中国鞘翅目系统分类研究提供参考,对农林害虫防治工作提供借鉴。 相似文献

The new genus 2Burmasphex is proposed for two fossil species, 2Burmasphex sulcatus sp. nov. and 2Burmasphex pilosus sp. nov., described from Myanmar Cretaceous amber. It exhibits many plesiomorphic features in relation to the extant Apoidea and is here provisionally allocated in the extinct family 2Angarosphecidae. 相似文献

Burmite (Burmese amber) from the Hukawng Valley in northern Myanmar is a remarkable valuable and obviously the most important amber for studying terrestrial diversity in the mid-Cretaceous.The diversity of Burmite inclusions is very high and many new taxa were found,including new order,new family/subfamily,and new genus.Till the end of 2016,14 phyla,21 classes,65 orders,279 families,515 genera and 643 species of organisms are recorded,which are summized and complied in this catalogue.Among them,587 species are arthropods.In addtion,the specimens which can not be identified into species are also listed in the paper.The information on type specimens,other materials,host and deposition of types are provided. 相似文献

Abstract: Bugs of two new genera and species are described as Buzinia couillardi and Tanaia burmitica . They are preserved in mid-Cretaceous amber from south-west France and northern Myanmar (Burma), respectively ( c . 100 Ma). These are the first formally described fossils of the heteropteran family Schizopteridae. Both belong to the subfamily Hypselosomatinae and are very similar to the extant genus Hypselosoma Reuter, providing evidence for the antiquity and morphological stability of this small bug family and the infraorder Dipsocoromorpha. Given the putative ecology of the fossils, a discussion is provided on the French and Burmese amber forest ecosystems. The geological setting of La Buzinie, a new amber deposit in south-west France that yielded the two specimens of Buzinia couillardi , is outlined. 相似文献

A new genus and new species of mantidflies, Doratomantispa burmanica n. gen., n. sp. (Neuroptera: Mantispidae), is described from Burmese amber. Diagnostic characters of the new genus are small body size, trichosors present around entire wing margin except basally, protarsus 5-segmented with paired, simple claws but no aroleum, profemur bearing six cuticular spines, inner surface of protibia with row of peg-like protrusions, Sc meets R1 in region of pterostigma, costal space greatly narrows toward wing apex, with 16 veinlets in costal space on front wing while costal veinlets on hind wing are replaced by trichosors and CuP absent in hind wing. The abdomen of the mantidfly is filled with large spheres resulting from a possible rickettsial infection. Phoretic heterostigmatid mites are adjacent to the wings of the fossil. 相似文献

A trypanosomatid (Trypanosomatidae: Kinetoplastida) associated with a blood-filled female sand fly in Cretaceous Burmese amber, is described in the new genus and species, Paleoleishmania proterus. The genus Paleoleishmania is established as a collective genus for digenetic fossil trypanosomes associated with sand flies. Amastigotes, promastigotes and paramastigotes are described. Paleoleishmania proterus is the first fossil kinetoplastid and provides a minimum age for the digenetic Trypanosomatidae. Its discovery indicates that vector-borne pathogens had been established by the Early Cretaceous. 相似文献

A new dustywing genus and species,namely Cretaconiopteryx grandis gen.& sp.nov.,from the mid-Cretaceous amber of Myanmar is herein described in the lacewing family Coniopterygidae.The new genus is distinguished from all other dustywing species by the combination of following morphological features:relatively large body-size,comparatively rich crossvenation,origin of RP+MA near wing base in both fore-and hindwing,forewing RA and RP terminally fused into a loop,and proximally zig-zagged forewing CuP.A new subfamily,Cretaconiopteryginae subfam,nov.,is erected based on this spectacular new genus.The new subfamily might represent the basalmost lineage of known coniopterygids. 相似文献

白垩纪缅甸琥珀昆虫化石研究是当前古昆虫学研究的热点之一。广腰亚目是膜翅目中的一个重要类群,其研究不仅为探讨膜翅目起源、早期演化、系统发育、不同地质时期古地理、古生态等方面提供重要的科学证据,而且可为陆地生态系统中的生物多样性研究提供重要材料。文中综述缅甸琥珀的研究简史及研究现状,阐述广腰亚目在印痕化石与缅甸琥珀中的特点、分布情况及该亚目在印痕化石与缅甸琥珀间的研究差异,进而探讨膜翅目广腰亚目化石当前研究现状、存在的问题及未来前景,并期望广大研究者增加对缅甸琥珀广腰亚目类群的关注和研究。 相似文献

Two new tribes in the Curculionoidea are described as the Anchineini Poinar and Legalov, n. trib. (Ithyceridae: Carinae) and Paleocryptorhynchini Poinar and Legalov, n. trib. (Curculionidae: Erirhininae). The genus Anchineus Poinar and Brown, 2009, n. placem. is transferred from the subfamily Curculioninae of the family Curculionidae to the subfamily Carinae of the family Ithyceridae. The genus Paleocryptorhynchus Poinar, 2009, n. placem. is transferred from the subfamily Cryptorhynchinae to the subfamily Erirhininae. The placement of the genus Mesophyletis Poinar, 2006 in the family Ithyceridae was confirmed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:0C0039DD-7BC6-4A54-9282-F43C5606D68B 相似文献

A new subfamily, genus and species of mayflies, Vetuformosa buckleyi n. gen., n. sp. (Ephemeroptera: Baetidae; Vetuformosinae n. subfam.), are described as the first representative of the family Baetidae from Early Cretaceous Burmese amber. The female fossil is characterised by unusually long antennae, two pairs of gonostyli representing a primitive appendiculate ovipositor, sensory patches on sternites 8, 9 and 10, protuberances on the egg chorion and the absence of a costal projection on the hind wing. This is the first documentation of such long antennae and a primary ovipositor in the Ephemeroptera. 相似文献
