A new species, Pangu yehuii Zhang and Rasnitsyn, n. sp., is described from the mid-Cretaceous (early Cenomanian) Kachin amber (Myanmar), which could be assigned to the family Panguidae (superfamily Panguoidea). Detailed morphology of the sting supports the position of Panguoidea as a basal clade within the infraorder Aculeata. Specifically, the presence of a sting with valvilli of distinctive morphology supports attribution to Aculeata and the fore wing with 2m-cu crossvein precludes its attribution to Chrysidoidea. Furthermore, the external position of metasomal tergum 7 and the equal number of antennomeres in both sexes differentiate it from the clade Apoidea + Vespoidea. A new genus Ceropangu n. gen. with Burmusculus mutatus Li et al., 2024 as its type species is systematically described, and an updated key to genera and species of Panguidae is also provided.
