Parabaissaeshna gen. nov.

Type species. P. ejerslevense sp. nov. by monotypy.

Etymology. Named after its similarity and relationship to the Cretaceous aeshnid genus Baissaeshna .

Diagnosis. This new genus is distinguished from all other fossil and recent genera within Aeshnidae by the following combination of forewing characters: basal space free; no ‘cordulegastrid gap’; only one lestine oblique vein a single cell distal of subnodus; pterostigma long, covering six cells; two rows of cells between RA and RP1 basal of pterostigma; very distinct pseudo-IR1 originating beneath middle of pterostigma, with three rows of cells between it and RP1 and RP2 respectively; IR2 unforked; midfork and triangle separated by six antefurcal cells; Rspl parallel to IR2 and Mspl parallel to MA with two rows of cells between these vein pairs respectively; two rows of cells in posttrigonal space close to triangle; no aeshnid bulla of MA developed; hypertriangle divided into five cells, triangle divided into seven cells, and subtriangle divided into two cells (this pattern probably is an autapomorphy of this new genus).
