The first flat wasps (Hymenoptera: Bethylidae) from Miocene Mexican amber

Abstract : Despite a fairly good number of Miocene insect-bearing deposits available worldwide, the bethylid wasps from this period are yet very poorly known. Here, we describe and figure three new species in three subfamilies, from the early to middle Miocene of Totolapa (Mexico): Goniozus cotyi sp. nov. (Bethylinae), Bakeriella nanyhelae sp. nov. (Epyrinae), and Solepyris electromexicanus sp. nov. (Scleroderminae). The cosmopolitan Goniozus Förster, 1856 was already known from the Miocene of Dominican Republic, whereas the Pan-American Bakeriella Kieffer, 1910 and the South-American Solepyris Azevedo, 2006 are recorded for the first time as fossil. Our finding expands the geographical distribution of the latter genus much northward in the New World.
