Quantitative Assessments and Taxonomic Revisions of the Genus <i>Urosyntexis</i> With New Species From Daohugou, China (Hymenoptera: Anaxyelidae)
Three new species of Urosyntexis , U. volita sp. nov., U. forta sp. nov., and U. ensia sp. nov., belonging to the subfamily Anaxyelinae of Anaxyelidae were described and figured based on three well‐preserved specimens from the Middle Jurassic Jiulongshan Formation of Northeastern China. We applied geometric morphometric analyses (GMA) to study 17 species with well‐preserved forewings of easily confused genera Syntexyela and Urosyntexis and presented the results for the first time. The GMA results further confirmed the classification of our new species and shed light on the differences between the two genera are mainly in the length of 5‐M and the emission position of 2r‐rs.
