Anolpocaros was first proposed as a subgenus of Aracana in 1855 by the German zoologist Johann Jakob Kaup.

[1] O. lenticularis was first described in 1841 by the Scottish naval surgeon, naturalist and Arctic explorer John Richardson with its type locality given as Australia.

[2] The 5th edition of Fishes of the World classifies this genus in the family Aracanidae which is in the suborder Ostracioidea within the order Tetraodontiformes.

The unarmed part refers to the lack of spines, while the allusion to wild boars may refer to these fishes being known as seapigs in the 19th Century, probably an allusion to the resmeblance of these fishes on a rear view to a pig.

[7] Anoplocapros boxfishes are endenic to the shallow coastal waters of southern Australia.
