Fossils belonging to Ripidiinae are rare. Here, we describe and figure a remarkable new genus and species of Ripidiinae, Protoripidius burmiticus gen. et sp. nov., from the Upper Cretaceous amber of Myanmar. Protoripidius can be placed in the extant subfamily Ripidiinae based on the widely separated and abbreviated elytra (in male), unfolded hind wings, simple claws and the absence of tibial spurs. Protoripidius bears many transitional features shedding new light on the relationships of the two extant tribes of Ripidiinae. The discovery also highlights the palaeodiversity of the subfamily Ripidiinae in the mid-Cretaceous. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Abstract: The extinct, exclusively Cretaceous wasp family Maimetshidae is newly recorded from Earliest Cenomanian Burmese amber. Two new genera and species are described. Burmaimetsha concava gen. et sp. nov., based on a male and a female, is most similar to Guyotemaimetsha Perrichot, Nel & Néraudeau, from Albian-Cenomanian French amber, but differs in its larger mandibles, distinctly concave face, elongate antennomeres, and forewing with cell [1Rs] smaller and fourth abscissa of Rs shorter. Maimetshasia kachinensis gen. et sp. nov., is based on a male, and is characterized by asymmetric mandibles with two and three teeth, by its forewing venation without cross-vein 2rs-m, with cell [1M] large and trapezoidal, and vein 2Rs+M very short, and by the hind wing without a free apex of Rs. The family was evidently widespread in the Cretaceous, and the new records extend the paleobiogeographical range to the South-East of Eurasia. A discussion about the possible biology of Maimetshidae is provided. [Copyright &y& Elsevier]
