Abstract
Endophytic oviposition is one of the most informative plant-insect interactions in the palaeontological record. A new ichnospecies of Paleoovoidus Paleoovoidus orientatus isp. nov., is established based on endophytic oviposition traces on a leaf of the conifer Podozamites Braun, 1843 from the Middle Jurassic Yanan Formation in the Ordos Basin, NW China. It is distinguished by the oviposition of straight rows of eggs distributed along the long axis of eggs and not completely parallel to the veins. These endophytic oviposition traces were probably made by a damsel-dragonfly (Odonata: Anisozygoptera) based on the comparison with recent Odonata oviposition and the co-occurrence of a damsel-dragonfly with endophytic behaviour. The find of damsel-dragonfly endophytic oviposition indicates an aquatic or waterside environment for the host plant.
