14, see text Agelenopsis, commonly known as the American grass spiders, is a genus of funnel weavers described by C.G.

The web is not sticky, but these spiders make up for that by running very rapidly.

The larger specimens (depending on species) can grow to about 19 mm in body length.

The main distinction between Agelenopsis and the related European genus Agelena consists of the pattern appearing on the cephalothorax; the former possesses two quasiparallel lines from the eyes to the beginning of the abdomen.

Another difference is the length of the front legs row in females, but in males, the similarities are not as in line.
