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.[1]
History and classification
Deinodryinus areolatus is known only from a single fossil, the
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.[1]
Description
The holotype specimen is a complete adult female preserved with areas of the face, vertex,
metanotum obscured. Overall the female is 4.5 millimetres (0.18 in) in length, with antennae that are less than three times the length of the head and macropterous hyaline wings. The antennae are composed of ten segments, densely hairy, and distinctly clavate, (club shaped) in structure. The mandibles have four teeth on each side, which progress from large to small. The tooth size changes in relation to the placement front to back on the mandible. The forewings have three cells at the base that are formed by pigmented veins. The forewings have a pterostigma that is approximately four times as long as it is wide, and a stigmal vein that is not S-shaped. The forelegs have a chelate structure, with the subapical tooth or other teeth.[1]
