Abstract

Abstract: A new subfamily, Burmadysagrioninae Zheng, Wang and Nel, subfam. nov., for the genus and species Burmadysagrion zhangi Zheng, Wang and Nel, gen. et sp. nov. is described from mid-Cretaceous Burmese amber. This is the third dysagrionid damselfly from the Mesozoic and the second one from Burmese amber. The new specimen has a unique discoidal cell with the anterior and posterior sides not parallel, and the basal side longer than the distal side, unlike the typical 'sieblosiid-dysagrionine' type. It differs from other dysagrionid damselflies by the presence of a simple wing venation, the vein IR1 originating below the pterostigma and a special discoidal cell. Graphical abstract: Highlights: A new damselfly subfamily is described from mid-Cretaceous Burmese amber. The damselfly is characterized by a simple wing venation, IR1 originating below the pterostigma and a special discoidal cell. The new discovery provides new data on the diversity and evolution of the discoidal cell.
