Lindsay's boxfish

Paraacanthostracion is characterised by having the anterior profile of the head being oblique with the diameter of its eye being only slightly less than the length of the snout. The space between the eyes is clearly concave. The carapace is quadrangular in shape with a poorly developed ridge along the middle of the back. There is a forward pointing spine before each eye and large spine in the middle of the back with another large spine, directed rearwards along the edge of the carapace near the anal fin. The hexagonal plate-like scales that make up the carapace are very rough towards its rear, as well as on the head. The body is irregularly streaked and spotted with grey and there are spots on the cheeks which show a tendency to merge to form short streaks.

Paraacanthostracion is found in the Southwestern Pacific Ocean where it is known only from the waters around New Zealand.

Paracanthostracion prefixes para-, meaning "close to", to the genus name Acanthostracion from which it differs in the shape of its carapace and the distribution of its spines. The specific name honours Phillipps's colleague at the Dominion Museum in Wellington, the curator of technology and taxidermist Charles John Lindsay.
