Deinodryinus areolatus is an extinct species of Deinodryinus in the wasp family Dryinidae. The species is solely known from an Eocene fossil found in the Baltic region.

Deinodryinus areolatus is known only from a single fossil, the holotype, specimen number PIN No. 964/60, which is housed in the A.A. Borissiak Paleontological Institute, Russian Academy of Sciences, in Moscow. The specimen is composed of a fully complete adult female wasp. The specimen is preserved as an inclusion in a transparent chunk of amber. The amber dates to between forty and forty-five million years old, and, being Baltic amber dispersed in the sea, a more specific type location than the Baltic region is not possible to identify. Deinodryinus areolatus was first studied by the Russian paleoentomologist Nadezdha Ponomarenko in 1975, with a redescription by paleoentomologists Adalgisa Guglielmino and Massimo Olmi, both of the University of Tuscia. Ponomarenko's 1975 type description of the new genus and species was published in the Russian journal Paleontologicheskiy Zhurnal, with the species placed by her into a new genus Electrodryinus.Electrodryinus was subsequently synonymized with Deinodryinus in a 1984 paper by Massimo Olmi, resulting in the current binomial Deinodryinus areolatus. D. areolatus was the first of three Deinodryinus species to be described from the fossil record. Deinodryinus velteni is also known from a fossil preserved in Baltic amber, while Deinodryinus? aptianus is known only from a Mongolian compression fossil in marl.
