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

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

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

The rachises of extant feathers, composed of dense cortex and spongy internal medulla, are flexible and light, yet stiff enough to withstand the load required for flight, among other functions. Incomplete knowledge of early feathers prevents a full understanding of how cylindrical rachises have evolved. Bizarre feathers with unusually wide and flattened rachises, known as “rachis-dominated feathers” (RDFs), have been observed in fossil nonavian and avian theropods. Newly discovered RDFs embedded in early Late Cretaceous Burmese ambers (about 99 million year ago) suggest the unusually wide and flattened rachises mainly consist of a dorsal cortex, lacking a medulla and a ventral cortex. Coupled with findings on extant feather morphogenesis, known fossil RDFs were categorized into three morphotypes based on their rachidial configurations. For each morphotype, potential developmental scenarios were depicted by referring to the rachidial development in chickens, and relative stiffness of each morphotype was estimated through functional simulations. The results suggest rachises of RDFs are developmentally equivalent to a variety of immature stages of cylindrical rachises. Similar rachidial morphotypes documented in extant penguins suggest that the RDFs are not unique to Mesozoic theropods, although they are likely to have evolved independently in extant penguins. 相似文献

A new family, genus and species of damselfly, Burmaphlebia reifi gen. et sp. nov. (Burmaphlebiidae fam. nov.), is described as the second fossil odonate from Early Cretaceous Burmese amber. Its phylogenetic position is discussed and the fossil is attributed to a new family at the base of the anisozygopteran grade, probably closely related to the Recent relict group Epiophlebiidae. It is the first record of the ‘anisozygopteran’ grade from amber and the smallest known representative of this group.http://zoobank.org/6EFE7288-BD89-42F9-BFA5-804CE6B904A6 相似文献

A new genus and species of mites, Protoresinacarus brevipedis gen. n., sp. n. (Acari: Heterostigmata: Pyemotoidea), is described from Early Cretaceous Burmese amber. This represents the first fossil record of a member of the family Resinacaridae. It is represented by 21 phoretic females adjacent to an adult mantidfly (Neuroptera: Mantispidae). This is the first record of phoresy of pyemotid mites on members of the insect order Neuroptera. The fossil mites differ from extant members of the family in possessing distinctly shorter legs I, which do not reach beyond the apex of the gnathosoma, and by the long setae v 1, v 2 and c 2. 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

Abstract: The spider family Oonopidae is described from Cretaceous ambers from Myanmar and Canada for the first time. Orchestina albertenis sp. nov. is the first spider to be described from Canadian Grassy Lake amber and only the second spider to be described from Canadian amber. The specimen in amber from Myanmar extends the known range of the extant genus Orchestina back another 10 million years from the previously oldest specimen in Turonian New Jersey amber. Despite being unknown as sedimentary fossils, Oonopidae occur in more fossil deposits than any other spider family and were already widespread by the Cretaceous. The family contains the oldest example of an extant spider genus along with Archaeidae, also from Burmese amber. 相似文献

【目的】产自缅甸北部胡康河谷的缅甸琥珀形成于白垩纪中期。其艺术价值很高,同时其内含物的生物多样性程度也很高,故其科学价值也不可估量。显微CT能够提供化石(琥珀)内部解剖结构的高分辨率断层图像,故该方法日渐成为目前琥珀研究中的常用方法之一。然而在可见光下可见的琥珀内的生物结构,在X射线下却有不同的结果,这与现生研究材料在显微CT下的表现非常不同。本研究对产自胡康河谷的9块缅甸琥珀进行显微CT检测,试图对这个特殊的现象进行较为系统的解读。【方法】利用数码相机(Nikon 5200D)拍摄琥珀照片,并用Helicon Focus 5.3软件合成。通过显微CT技术扫描琥珀和计算机断层重建技术重建出缅甸琥珀内含物的三维结构形态。【结果】显微CT检测结果主要分为3种:完全无衬度、部分结构有衬度和整体结构有较好衬度。本研究对有较好衬度的琥珀内含物进行了三维重建,展示了琥珀内含物的外部和内部三维结构。【结论】琥珀内含物的可见光成像和X射线成像不存在一一对应关系,其原因和琥珀保存的好坏以及琥珀的密度差、琥珀围岩之间的对比度差异有关。琥珀形成和埋藏过程中的物理和化学变化非常复杂,其机理的探究也更为复杂和困难,本文对这个现象的主要类型做了较为初步的阐述,后续研究需要更为全面的选样和更为严格的实验设计才能够最终解决这个埋藏学上的难题。 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
