Author of the name: Hentz.
Female: 18 to 25 mm.
Male: 16 to 18 mm.
According to How to Know the Spiders, this species has a thin line of yellow hairs in the eye area and a more spotted venter than carolinensis. It also has banded legs.

According to Penn State Entomology, here's a description:

"Hogna(Tigrosa) aspersa females are 18 to 25 millimeters in length, and the males are 16 to 18 millimeters. They are similar to H. carolinensis in body color but have a distinct narrow line of yellow hairs on the carapace in the vicinity of the eyes. The legs are banded with a lighter brown color at the joints. The males are much lighter in color than the females, and only their third and fourth pairs of legs are banded with a lighter color."
