The nearest ally of this species will prove to be A. paradoxus H. Deyr. from the island of Makian (Ann. Soc. Ent. Belge. VIII. p. 223, and p. 227, pl. 4 fig. 20). It has a length of about 3—3 1/2 mm, and is of a blackish bronze colour, bright bronze on the head and pronotum. — The whole insect is covered with an extremely fine and dense sculpture which is only visible with the aid of a lens of strong power.
