Ankothrips
Ankothrips is a genus of thrips in the family Melanthripidae. It is recognized as the most ancient extant thrips genus, with fossil evidence indicating an origin in the Early Cretaceous period approximately 94 million years ago. The genus exhibits remarkable morphological stability over this timespan, with two fossil species described from French amber: Ankothrips dupeae from the Late Cretaceous and Ankothrips deploegi from the earliest Eocene. This long-term morphological conservatism is rare among insects.
