new gomphaeschnid dragonflies odonata anisoptera aeshnoptera from mid cretaceous burmese amber
Cretaceous Research, 2019Co-Authors: Haichun Zhang, Andre Nel, Daran Zheng, Edmund A Jarzembowski, Jun Wang, Bo WangAbstract:Abstract A new true Dragonfly, named Kachinaeshna zhuoi Zheng, Nel and Wang, gen. et sp. nov., is described from Cretaceous Burmese amber representing the second gomphaeschnaoidine from this deposit. Kachinaeshna Zheng, Nel and Wang, gen. nov. differs from other Gomphaeschnaoidinae in: the absence of an elongate distal paranal cell, directly basal of the anal loop, in the hindwing; a distinct curvature of RP2; and a curve of RP1 at the pterostigmal brace. The gomphaeschnaoidine dragonflies were previously only recorded from the Lower Cretaceous and mainly from the upper Aptian Crato Formation of Brazil. Based on the true Dragonfly fossils found in Burmese amber, a possible late Early Cretaceous age is supported for Burmese amber.

a new gondwanan Dragonfly odonata anisoptera araripegomphidae from mid cretaceous burmese amber
Cretaceous Research, 2018Co-Authors: Haichun Zhang, Andre Nel, Daran Zheng, Edmund A Jarzembowski, Suchin Chang, De Zhuo, Bo WangAbstract:Abstract The fossil Dragonfly is a perfect model to study past biogeography. Araripegomphidae is an ancient Gondwanan family comprising the sole genus Araripegomphus previously from the Crato Formation (Upper Aptian) of Brazil. For the first time, a non-rock find, Araripegomphus shai sp. nov., is here described from mid-Cretaceous Burmese amber. This rare araripegomphid Dragonfly extends the range of Araripegomphus to the west Burma block.

new cymatophlebiid dragonflies from the lower cretaceous of china and england odonata anisoptera cymatophlebiinae valdaeshninae
Cretaceous Research, 2018Co-Authors: Edmund A Jarzembowski, Daran Zheng, Bo Wang, Suchin Chang, Haichun ZhangAbstract:Abstract Cymatophlebia y ixianensis sp. nov., the first Chinese Cretaceous cymatophlebiid Dragonfly (cymatophlebiine), is described from the Lower Cretaceous Yixian Formation of western Liaoning, NE China. Cymatophlebia y ixianensis sp. nov. has a forked RP2 near the wing margin differing from other species of Cymatophlebia Deichmuller 1886. A new valdaeshnine Dragonfly, Valdaeshna mikei sp. nov., is described from the Lower Cretaceous Upper Weald Clay of southern Surrey, SE England, differentiated from Valdaeshna surreyensis Jarzembowski, 1988 in its larger size, a long Pt-brace, and a broad area between Rspl and IR2. An updated diagnosis for Valdaeshna Jarzembowski, 1988 is proposed.

new early cretaceous Dragonfly sinojagoria magna li et al 2012 odonata gomphaeschnidae emending the chinese tribe sinojagorini
Cretaceous Research, 2017Co-Authors: Daran Zheng, Bo Wang, Suchin Chang, Haichun ZhangAbstract:The monotypic Dragonfly tribe Sinojagorini was only recorded from the Lower Cretaceous Yixian Formation of the Huangbanjigou outcrop of western Liaoning, NE China. Its diagnostic characters are incomplete because its subordinates were established based on forewings and fragmentary hindwings or only forewings. A well-preserved Dragonfly attributed to Sinojagoria magna Li et al., 2012 is described herein from the same horizon and locality of the type specimen, not only improving the description of this species but also providing additional diagnostic characters for Sinojagorini. The new specimen further supports the sister-group relationship between Sinojagorini and the remaining Gomphaeschnaoidinae.

the first aeshnoid Dragonfly odonata anisoptera telephlebiidae from mid cretaceous burmese amber
Cretaceous Research, 2017Co-Authors: Daran Zheng, Edmund A Jarzembowski, Suchin Chang, Bo WangAbstract:Abstract A new true Dragonfly, Cretaeshna lini gen. et sp. nov., is described based on a forewing from mid-Cretaceous Burmese amber. Cretaeshna is probably a member of Telephlebiidae: Telephlebiinae, but differs from the latter in having a weakly-defined IR1 and a short pterostigma. Cretaeshna lini is the first aeshnid Dragonfly to be found as an amber inclusion and the third Cretaceous true Dragonfly recorded in amber. Our find augments the diversity of Mesozoic true dragonflies, and enhances our understanding of the palaeogeographic distribution of aeshnid dragonflies.
