Belongs within: Cyclominae.

Acantholophus is an Australian genus of often heavily spinose weevils. It may be divided between two sections, one of which has the head separated from the rostrum by an intercristal ridge and possesses postocular lobes on the pronotum, whereas the other has a transverse sulcus between head and rostrum and postocular lobes are absent (Zimmerman 1993).

Characters (from Zimmerman 1993): Longitudinal dorsal contour of head and rostrum more concave than convex; hypostomal angles appearing on sides of oral cavity well removed from ventral margin, ventral edges of mandibles and ventral margin of oral cavity widely separated, labium and maxillae in resting position widely exposed to view from beneath; scrobe directed mostly toward eye; antennal scape reaching caudad of middle of caudal margin of eye; postmentum not lobate, lower margin of oral cavity at most slightly convex; pronotum and elytra with numerous large, conspicuous conical processes; procoxal cavities confluent, procoxae contiguous.
