[1][3][4] Armadilliidum teramense was described as a distinct species of Armadillidium in 1933, based on specimens collected from the Province of Teramo.

The secondary antennae have thick lobes that don't bend backwards and are deeply furrowed in an arch at their posterior surface.

[1][3] Concerning the sexual characters of the male, the seventh pereiopod is slightly indented ventrally and decorated with a hair-field at its apical part.

The posterior lobe of the exopodite of the first pleopod is triangular and the apex of the endopodite bends slightly outwards.

The only known details concern the collection data of the type series, which was found under sandstones on loamy-sandy soil, on the desolate, grassy mountain slopes of Teramo.
