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 genus Mesosticta Huang, Azar, Cai et Nel, 2015 was established based on the wing bases of two damselflies from mid-Cretaceous Burmese amber. Here we describe a new well-preserved platystictid damselfly, Mesosticta electronica sp. nov., with complete forewings and hindwings. The diagnosis of Mesosticta is revised and augmented in this paper. Mesosticta electronica sp. nov. differs from Mesosticta burmatica Huang, Azar, Cai et Nel, 2015 in having the arculus slightly distal of Ax2, a free subdiscoidal cell, the hindwing AA ending on the middle area of the posterior side of the discoidal cell, and the base of RP2 being three or four cells distal of the subnodus. The new discovery adds to the diversity of damselflies in mid-Cretaceous Burmese amber and puts the origin of Platystictidae to at least the mid-Cretaceous. 相似文献

A New Species of the Family Juraperlidae(Insecta:Grylloblattida)from the Middle Jurassic of China 总被引：1，自引：1，他引：0
<正>Juraperla grandis sp.nov.(Grylloblattida:Juraperlidae) is described from the Daohugou locality (Middle Jurassic,China).Its wing venation is very similar to that of Juraperla daohugouensis Huang and Nel,2007 (Grylloblattida:Juraperlidae),in the particular occurrence of a supplementary longitudinal vein in the area between the anterior wing margin and ScP.The larger size of the new specimen,the lower number of CuA1 branches,and the occurrence of two rows of cells between MP and CuA in forewings justify the erection of a new species,J.grandis sp.nov..The material also preserved hind wing and body structures,described for the first time in Juraperlidae. 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

：Yumushan
block on the north margin of Qilian mountain, with Jiudong basin and Minle basin to the
west and east respectively, belongs to the fore-land depression in NNW direction at the
north margin of the Qilian mountain fold belt. The Yumushan block has been thought of as a
fault-uplift, which separates the two basins formed during late Yanshanian orogeny.
However, the recognition of fault zones at the western margin of the Yumushan block, and
the tectonic and sedimentary analyses of the Yumushan block and the basins, cast doubts to
the tectonic property of the block. It is suggested that the two basins be derived from an
united large basin at least during Mesozoic and the Yumushan block be nappe sheet formed
due to NE imbricate thrusting on the north margin fault zone of the Qilian mountain. This
proposal would provide valuable clues to further exploration of oil-gas and water
resources in Hexi corridor basin belt. 相似文献

Two new genera and species of Cretaceous webspinners (Embiodea) are described and figured, both preserved in amber from northern Myanmar. Atmetoclothoda orthotenes Engel and Huang, gen. et sp. nov., is the first fossil representative of the putatively primitive family Clothodidae, and is segregated into its own subfamily, Atmetoclothodinae Engel and Huang, subfam. nov., owing to its primitive retention of a distinct mentum, a quadrate submentum with straight borders, a postocciptal suture that meets the hypostomal sulcus at the posterior tentorial pit, and subgenae that do not meet medially (thus a ventral bridge or gula is lacking), completely symmetrical terminalia, and unsegmented cerci that apically bear a small inner lamellar projection. Litoclostes delicatus Engel and Huang, gen. et sp. nov., is the first definitive fossil of Oligotomidae (not including a subfossil species in Pleistocene copal and which is likely synonymous with an extant taxon), and differs from modern genera in a combination of head, tarsal, and terminalic morphology. The new fossil species double the known Cretaceous fossils and add a further two families to the Mesozoic record for the order. 相似文献

A remarkable new wasp of the superfamily Evanioidea (Apocrita: Evaniomorpha) is described and figured from a female preserved in mid-Cretaceous amber from the Hukawng Valley of northern Myanmar. Othniodellitha mantichora Engel and Huang, gen. et sp. nov., is characterized by its unique combination of primitive and derived features in mesosomal and metasomal construction and wing venation, along with its peculiarly blocky head with a prominent facial horn, clypeal projection, and massive, squared mandibles, among other traits. The genus is placed in the new family, Othniodellithidae Engel and Huang, fam. nov., and is among the lower Evanioidea and distinguished from the Praeaulacidae and other Mesozoic evanioid families. 相似文献

A new genus and species of Mesozoic alderfly is described as Haplosialodes liui gen. et sp. nov., and from an adult male preserved in Cretaceous Burmese amber. The new genus is closely related to the genera Haplosialis Navás (Recent fauna of Madagascar), Indosialis Lestage (Recent fauna of Southeast Asia), and Eosialis Nel et al. (Eocene of France), suggesting a possible Early Cretaceous age for the clade that comprises these groups. 相似文献

The dysagrionid damselflies are relatively diverse in Burmese amber, with two genera already recorded. A new dysagrionid damselfly, Electrodysagrion lini Zheng, Nel and Wang, gen. et sp. nov., corresponding to the oldest record of the tribe Dysagrionini, is described herein. It has the unique ‘sieblosiid-dysagrionine’ type of discoidal cell. It differs from other genera of Dysagrionini in having no antenodal crossveins distal of Ax2, Arc aligned with Ax2, and only one row of cells in the cubito-anal area below the nodus. This find puts the origin of Dysagrionini back to at least the mid-Cretaceous. 相似文献

A new Mazon-Creek-type fossil specimen is described as Sumixam maximus gen. and sp. nov., assigned to the taxon Archaeorthoptera Béthoux and Nel, 2002 (composed of Orthoptera and some fossil relatives): it exhibits one of the diagnostic character states of this taxon, which is the fusion of CuA (emerging from M + CuA) with CuP, or a branch of it. A more precise taxonomic assignment is out of reach. The new taxon exhibits a fusion of the anterior branch of MA with RP, and a point of divergence of MA and MP located near the point of divergence of CuA (from M + CuA), but lack a branching of CuPa. This unique combination of character states is probably derived with respect to a number of contemporaneous species. Sumixam maximus gen. and sp. nov. is most likely the closest known relative of the panorthopterans, which include all the recent Archaeorthoptera. 相似文献

A new genus with one new species and five new species of genus Amblomma of fossil ommatids are described and illustrated： Euryomma tylodes gen. et sp. nov., Amblomma cyclodonta sp. nov., Amblomma miniscula sp. nov., Amblomma porrecta sp. nov., Amblomma eumeura sp. nov., and Amblomma protensa sp. nov. All of them were collected from the Upper Jurassic or Lower Cretaceous Yixian Formation of western Liaoning, China. A key to the species of Amblomma is given. The wide epipleural space shows that Euryomma may be a primitive genus in Ommatidae. Many different species of Amblomma occurred within the same sedimentary horizon in this area could be environmental changes caused by frequent volcanic activities during the deposition of the Yixian Formation. 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
