A new genus of anaxyelid wood wasps from the mid-Cretaceous and the phylogeny of Anaxyelidae (Hymenoptera)

Two new species of wood wasps (Anaxyelidae), Orthosyntexis elegans gen. et sp. nov. and thanti , are described from mid-Cretaceous Kachin amber. exhibits characters character combinations unique to the family, such as combination two mesotibial spurs, a length ratio forewing 1Rs 1M<1, width cell 1mcu ≥ 2, presence 2M+Cu in hind wing. The morphological allow for an exploration anaxyelid phylogeny. phylogenetic results indicate that Anaxyelidae monophyletic it is suggested classify genera subfamilies, Syntexinae Anaxyelinae, latter including Kempendajinae Dolichostigmatinae.
