Sahydroaraneus is a genus of spiders in the family Theraphosidae.

[2] They are hirsute, featuring long setae on the fourth tarsi.

They have thick black setae on the dorsal surface of the chelicerae.

The primary tibial apophysis consists of a basal stalk, from which arises a thin, elongated black spine.

[3] They usually live in moist deciduous forests under rocks or decaying logs and make a horizontal tubular network of webs for retreat.
