Koreatriassothemis elongatus gen. et sp. nov. is the first representative of the odonatan superfamily Triassolestoidea described from the Upper Triassic of the Republic of Korea. Despite close similarities with the genera Pseudotriassothemis and Triassoneura, exact affinities within Triassolestoidea remain uncertain, thus discoveries of more complete triassolestoid fossils are required to resolve relationships. The identification of K. elongatus gen. et sp. nov. shows that Odonatoptera and Triassolestoidea diversity was high during the Late Triassic and is currently underestimated. A ‘Samarura-like’ odonatopteran nymph is also identified from the same Upper Triassic outcrop, and may be referable to K. elongatus gen. et sp. nov.
