New Euthemistid Damsel–Dragonfly from the Middle Jurassic of Northern China (Odonata, Isophlebioidea, Euthemistidae)

A new genus and new species of the euthemistid, Kidaneuthemis ningchengensis gen. et sp. nov., is described from the Middle Jurassic of Inner Mongolia, China. It can be assigned to the Euthemistidae by the several long intercalary veins between RP1 and IR1, IR1 and RP2, as well as between RP2 and IR...

Summary:A new genus and new species of the euthemistid, Kidaneuthemis ningchengensis gen. et sp. nov., is described from the Middle Jurassic of Inner Mongolia, China. It can be assigned to the Euthemistidae by the several long intercalary veins between RP1 and IR1, IR1 and RP2, as well as between RP2 and IR2 and between IR2 and RP3/4. Kidaneuthemis ningchengensis gen. et sp. nov. distinguishes from the other two genera of this family by the presence of not less than eight intercalary veins between MP and wing margin; about three rows of cells in the distal part between MA and MP; the base of IR2 is two cells distal to that of RP3/4. In addition, a revision of the family Euthemistidae has been proposed.
