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

腹足类化石在地层中丰富且常见,但在琥珀中保存较少。文中描述了产自白垩纪中期缅甸琥珀中的陆生腹足类化石2属2种:Euthema naggsi Yu, Wang and Pan, 2018, Truncatellina dilatatus sp. nov.。这些陆生腹足类新材料的发现,提高了缅甸琥珀中陆生腹足类物种多样性,并进一步印证了白垩纪中期缅甸琥珀森林温暖潮湿的热带雨林环境。 相似文献

近五年,缅甸北部白垩纪中期克钦琥珀中相继发现了数百枚蜻蜓目化石,包含现生蜻蜓目三个亚目类群,目前已发表16科29属35种,在所有已知琥珀记录中数量和多样性最高。克钦琥珀中的蜻蜓目以均翅亚目(豆娘)为主,以Burmahemiphlebia zhangi最为常见,不少现生豆娘的化石记录也首次在克钦琥珀中发现,包括Perilestidae,Platycnemididae和Platystictidae等。此外,克钦琥珀中发现了一些中生代沉积岩中常见的蜻蜓目类群,如Araripegomphidae, Gomphaeschnidae和Stenophlebiidae等,指示克钦琥珀的时代可能为早白垩世晚期。这些发现为探讨蜻蜓目部分类群的起源、演化和揭示生物古地理提供了有力证据。 相似文献

在白垩纪中期(~100 Ma)缅甸琥珀中首次报道了蕨类植物鳞片化石。该鳞片化石为基部着生,鳞片细胞壁均存在不同程度加厚,为筛孔状鳞片类型。根据最新的现代蕨类植物系统发育树,结合鳞片的演化趋势及鳞片化石的形态解剖特点分析,认为该鳞片化石来自真水龙骨类。这一发现表明真水龙骨类在白垩纪中期就已经出现了多样性分化。 相似文献

AbstractBurmese amber is an extremely important source of mid-Cretaceous plant and animal remains with over 870 species of organisms, ranging from protozoa to vertebrates, described from this source. The amber mines are located on the West Burma Block that according to geologists was originally part of Gondwana. The present study introduces some angiosperms and insects in Burmese amber whose closest extant relatives have a Gondwanan distribution and there is no previous evidence of a Laurasian distribution. Based on this evidence, it is proposed that organisms in Burmese amber represent a selection of tropical to subtropical life forms that inhabited the interconnected continents of Gondwana in the Early Cretaceous. Based on the fossil record of angiosperms and their diversity in Burmese amber, the West Burma Block could not have rafted from Gondwana to SE Asia before the Early Cretaceous. 相似文献

缅甸琥珀生物群产自距今约98.8Ma的白垩纪中期,该生物群是世界上物种多样性很高的琥珀生物群之一,为了解白垩纪中期生物多样性和古生态提供了重要窗口。文中以近年来缅甸琥珀地层学、琥珀生物学研究为依据,总结缅甸琥珀形成环境,并对缅甸琥珀揭示的昆虫与植物的协同演化、昆虫的捕食、社会性证据、寄生、求偶和结构色等方面的研究结果进行总结,以期较全面地综述缅甸琥珀的古环境和昆虫行为生态学特征。 相似文献

Abundant odonatans have been discovered from mid-Cretaceous Burmese amber, and Burma has played an important role in early damselfly diversification during the mid-Cretaceous. In this paper, a new damselfly, Palaeodisparoneura cretacica sp. nov., is described from Burmese amber. It is the second species of the extinct genus Palaeodisparoneura Poinar, Bechly et Buckley, 2010. P. cretacica sp. nov. differs from P. burmanica Poinar, Bechly et Buckley, 2010 in having more postnodal and postsubnodal crossveins, the base of IR1 being more cells distal of the base of RP2, a hyaline pterostigma and a longer RP3/4. Our find increases the diversity of damselflies during the mid-Cretaceous. 相似文献

A rare archaic beetle, Mallecupes qingqingae gen. et sp. n., (Insecta: Coleoptera: Archostemata: Cupedidae) is described from mid-Cretaceous Burmese amber. It shows affinity with Paracupes found in South America today and ‘Paracupes’ found in North America during the Cretaceous. Archostemata are diverse in Burmese amber. 相似文献

A new species of pelecinid wasp, Eopelecinus marechali sp. nov., is described and figured from mid-Cretaceous Burmese amber based on a single well-preserved female specimen. Contrary to Eopelecinus inopinatus Jouault et al., 2020a, unique other Eopelecinus known from this deposit, the new species is based on a complete female specimen. This discovery confirms that the Pelecinidae were highly diverse during the Cretaceous and highlights the underestimated diversity of the genus Eopelecinus in Burmese amber biota. Eopelecinus marechali sp. nov. differs from all other Eopelecinus species by its unique metasomal ratio. A summary on the fossil pelecinid species with distributions and ages is provided. Based on the particular geological history of the West Burmese Terrane and the fossil record of the family, the hypothesis of an Asian origin of the family is discussed. The records of Eopelecinus in both Laurasia and Burmese amber biota, during the mid-Cretaceous, suggest that possible transfers of fauna have taken place between these two geological blocks. 相似文献

Four new laniatorean harvestmen specimens (Arachnida: Opiliones: Laniatores) are described from the mid-Cretaceous (upper Albian–lower Cenomanian) Burmese amber of Northern Myanmar. One is placed as Insidiatores indet., but is not formally named as it is probably immature. Burmalomanius circularis n. gen. n. sp. and Petroburma tarsomeria n. gen. n. sp. represent the first fossil records of the extant families Podoctidae and Petrobunidae respectively. Finally, Mesodibunus tourinhoae n. gen. n. sp. belongs to Epedanidae, a family previously recorded from Burmese amber. These new records bring the total number of Burmese amber laniatorean species to ten, and the total number of fossil laniatoreans to fifteen. The new finds offer additional calibration points for the Laniatores tree of life and are consistent with the hypothesis that the modern Laniatores fauna of Southeast Asia may have had Gondwanan, as opposed to a Laurasian, origins. 相似文献

A new genus and species of anaxyelid wasp is described and figured from the mid-Cretaceous Burmese amber as Curvitexis kopylovi gen. et sp. nov. The placement of this new genus within the Anaxyelidae is corroborated by its wing venation and the configuration of its mesosoma. This new genus differs from all other Syntexinae from the mid-Cretaceous Burmese amber biota, inter alia, owing to its forewing with the vein 1Rs curved and longer than 1M, the crossvein 1r-rs absent, the vein 2Rs + M present; the hind wing with the abscissa 2M + Cu present, the vein m-cu absent, and the cell r closed. The recently described Paraxiphydria resinata Gao et al., 2022 is transferred to Anaxyelidae: Syntexinae, and the subfamily Paraxiphydriinae Gao et al., 2022 is synonymized under Syntexinae. 相似文献

SCHIZOPTERID BUGS (INSECTA: HETEROPTERA) IN MID-CRETACEOUS AMBERS FROM FRANCE and MYANMAR (BURMA) 总被引:1,自引:0,他引:1
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
