The additional specimen, along with the three A. exhumatum fossils are currently residing in the Museum of Comparative Zoology paleoentomology collections at Harvard University.

[1] A. scudderi was first studied by Theodore Cockerell with his 1906 type description being published in the journal Bulletin of the Museum of Comparative Zoology.

[1] The specific epithet "scudderi" was coined by Theodore Cockerell in honor of Samuel Scudder who collected the specimens at Florissant.

The abdomen in contrast is light in tone, possibly yellow in life, with the posterior edges of each segment darkening into a distinct stripe.

The dark colored forewings of A. scudderi are 8 millimetres (0.31 in) in length and notably hairy in the basal region.
