摘要
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.(C) 2016 Academie des sciences. Published by Elsevier Masson SAS. All rights reserved.
