Zheng, D., Nel, A., Jarzembowski, E.A., Chang, S.-C., Zhang, H. & Wang, B., May 2018. Exceptionally well-preserved dragonflies (Insecta: Odonata) in Mexican amber. Alcheringa xxx, xxx–xxx.
Dragonflies (odonatans) are comparatively rare as amber inclusions, and most are not well preserved on account of their size. Here, we report a single piece of Mexican amber with one complete dragonfly and two damselflies. The dragonfly is attributed to the extant gomphid Erpetogomphus Selys Longchamps, and the damselflies belong to the extant coenagrionid Argia Rambur. Both genera are nowadays distributed widely in Mexico. The new discovery dates the origins of these two genera to the Miocene at least.

New damselflies (Odonata: Zygoptera: Hemiphlebiidae, Dysagrionidae) from mid-Cretaceous Burmese amber. Alcheringa 41, 12–21.[Taylor &; Francis Online], [Web of Science ®], [Google Scholar] is the dominant damselfly found in Burmese amber. Here, a new hemiphlebiid damselfly, Burmahemiphlebia hui sp. nov., is described representing the second Burmahemiphlebia species discovered in Burmese amber. Burmahemiphlebia hui sp. nov. differs from Burmahemiphlebia zhangi in having more postnodal cross-veins, CuP and the separating point of AA from AP basal of A?×?1, Arc aligned with A?×?2, RP2 base closer to N than to Pt, and IR1 five cells distal of RP2 base. The new damselfly is extremely rare and the only one known from Burmese amber, unlike Burmahemiphlebia zhangi.Daran Zheng* [dranzheng@gmail.com], Bo Wang?

ISSN 0311-5518.Magnaxyela rara gen. et sp. nov. and Abrotoxyela curva sp. nov. (Xyelidae, Macroxyelinae, Gigantoxyelini) are described from the Middle Jurassic Jiulongshan Formation at Daohugou Village, Inner Mongolia, China. The two new species are confidently assigned to tribe Gigantoxyelini of subfamily Marcroxyelinae based on their wing venation and various other morphological characters. Magnaxyela rara is established based on the following forewing characters: pterostigma sclerotized completely, Sc two-branched and meeting R before origin of Rs, 1-Rs as long as 1-M, but shorter than Rs?+?M, R curved bewteen 1r-rs and 2r-rs and cell 2r longer than 1r. Abrotoxyela curva is differentiated from congeneric forms by the two-branched vein Sc of the forewing, Sc2 short and inclined towards the base of the wing, 1-Rs, 1-M and Rs?+?M nearly equal in length, crossvein 1m-cu longer than 1cu-a. The fossils described herein increase the diversity of the Mesozoic Xyelidae.Yan Zheng* [zhengyan536@163.com], Jun Chen* [ubiscada@sina.com], and Junqiang Zhang [zhangjunqiang@lyu.edu.cn], Institute of Geology and Paleontology, Linyi University, Shuangling Road, Linyi 276000, PR China; Haichun Zhang [hczhang@nigpas.ac.cn], State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, East Beijing Road, Nanjing 210008, PR China. *Also affiliated with: State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, East Beijing Road, Nanjing 210008, PR China.相似文献
