Acanthogonatus chilechico is a mygalomorph spider of Chile, its name arising from its type locality: Chile Chico, Valdivia, Region X (de los Lagos), Chile. This species is most similar to A. notatus, but is distinguished by a less developed embolar flange and by having the basal portion of the bulb narrower in lateral view, and the presence of more numerous spines on its metatarsus I.
