Abstract A new species of plumalexiid wasp, Plumalexius ohmkuhnlei sp. nov., is described from the mid-Cretaceous Myanmar (Burmese) amber, based on a single male specimen. It is compared with the only other known plumalexiid, Plumalexius rasnitsyni Brothers, from the Turonian New-Jersey amber, and provides additional information confirming the relatively basal status of the family within Chrysidoidea.
