A new anaxyelid wood wasp (Hymenoptera: ‘Symphyta’) from the mid-Cretaceous Burmese amber

A new genus and species of anaxyelid wasp is described and figured from the mid-Cretaceous Burmese amber as Curvitexis kopylovi gen. et sp. nov. The placement of this new genus within the Anaxyelidae is corroborated by its wing venation and the configuration of its mesosoma. This new genus differs from all other Syntexinae from the mid-Cretaceous Burmese amber biota, inter alia, owing to its forewing with the vein 1Rs curved and longer than 1M, the crossvein 1r-rs absent, the vein 2Rs + M present; the hind wing with the abscissa 2M + Cu present, the vein m-cu absent, and the cell r closed. The recently described Paraxiphydria resinata Gao et al., 2022 is transferred to Anaxyelidae: Syntexinae, and the subfamily Paraxiphydriinae Gao et al., 2022 is synonymized under Syntexinae.
