Hymenoptera fossil insects Disogmini Burmese amber new taxa


Cresogmus grimaldii Rasnitsyn & Kolyada gen. et sp. nov. is described from the mid-Cretaceous Burmese amber in the tribe Disogmini (subfamily Proctotrupinae) as the first representative of the family Proctotrupidae encased in Burmese amber. This new genus is diagnosed by the occipital carina extending to the lower half of the head, the pronotum lacking an epomia, the pterostigma short, the petiole open but very short, the ovipositor wide and bent throughout, with its apex widely rounded. Diagnostic characters of Disogmini are revised.
