Abstract
A new species Pseudocymatophlebia bisecta sp. nov. (Odonata: Aktassiidae) is described from the Lower Cretaceous of China. It is assigned to this family by the typical very dense wing venation with a distinctly increased number of cells in the regions of R and M, the area between RP3/4 and MA widened near the posterior wing margin on forewing, with more than three rows of cells; RP3/4 undulate and distally diverging from MA. Pseudocymatophlebia bisecta sp. nov. differs from the other two species of this genus by discoidal triangle two-celled, elongate and wide in both fore- and hind wings. In addition, a revision of the genus Pseudocymatophlebia has been proposed.
