History and classification
Deinodryinus velteni is known only from a single fossil, the
Description
The holotype specimen is a complete adult female with an overall coloration that is brown to black, except the palpi, which are a dull brick red. The female is 4.0 millimetres (0.16 in) in length, with antennae that are approximately three times the length of the head and macropterous forewings. The antennae are composed of ten segments, densely hairy, and distinctly club-shaped (clavate) in structure. The forewings have three cells at the base that are formed by pigmented veins. The forewings have a pterostigma which is approximately five times as long as it is wide, and a stigmal vein that is not S-shaped. Both the fore and hind wings are uniformly slightly darkened, rather than the glassy hyaline seen in the other two described fossil species of Deinodryinus. The length of the stigmal vein is used to separate D. areolatus and D. velteni, with the distal portion of the vein being much longer than the proximal portion in D. velteni as opposed to D. areolatus where the two portions are approximately the same length.[1]
