Hybristodryinus moutesoe (Hymenoptera, Dryinidae), a new species from mid-Cretaceous Kachin (Burmese) amber

Dryinidae are parasitoid wasps within the aculeate (Hymenoptera) superfamily Chrysidoidea that are known for the pincer-like chela that most females use to restrain their hosts and prey (Auchenorrhyncha). Herein, a new species of the genus Hybristodryinus Engel, 2005 is described from mid-Cretaceous Kachin (Burmese) amber. Hybristodryinus moutesoe sp. nov. is diagnosed, described, and incorporated into the pre-existing key to Hybristodryinus. The new species is most similar to H. mon Perkovsky, Olmi, Muller and Martynova, 2019, but differs in characteristics of the pronotum, greater distance between notauli, and greater distance between inner edges of the lateral ocelli (POL). A review of the Dryinidae from Kachin (Burmese) amber is also included. (C) 2020 Elsevier Ltd. All rights reserved.
