A new species of Cretevania Rasnitsyn, 1975 (Hymenoptera: Evaniidae) from the mid-Cretaceous Kachin amber

Résumé

Cretevania kachinensis sp. nov., a new species of evaniid wasp (Hymenoptera: Evaniidae), is described and illustrated from a male specimen preserved in the mid-Cretaceous Burmese amber of the Noije Bum deposits (Myanmar). Cretevania kachinensis sp. nov. is readily attributed to the genus Cretevania because of its forewing venation (i.e., forewing with cell 1+2r elongate, longer than 3r and more than twice as long as pterostigma length, 3r narrower triangular, nearly as wide as 1+2r), but differs from all other species mainly because of its veins 2Rs+M (more developed than a simple contacting point) and 1Rs (subvertical to R), and the cell 2cua conformation (i.e., rectangular). This description highlights the underestimated diversity of evanioids in the mid-Cretaceous Kachin amber.
