Acanthogonatus patagallina is a mygalomorph spider of Chile, named after its type locality: Pata de Gallina, Arauco, Region VIII (Bío Bío Region).[1] This species is closest to A. nahuelbuta, but is distinguished by having the basal portion of the male's bulbal duct more sinuous and the basal portion of its bulb more rounded in lateral view.
