Acanthogonatus peniasco is a mygalomorph spider of Chile, its name arising from its type locality: El Peñasco, Linares, VII Region (del Maule), Chile. Females differ from those of A. franki and A. recinto in the shorter, wider, and more sclerotized spermathecal ducts, and from those of other species in the genus by having 1-1-1 P spines in the patella IV.
