Philinopsis gigliolii is one of a number of similarly coloured species found in temperate parts of the Pacific. As in Philinopsis troubridgensis and Philinopsis taronga, P. gigliolii had a mottled or reticulate brown pattern on an essentially translucent background. In all species there are patches of yellow. P. gigliolii was originally described from Japan, and there have been few subsequent sightings. This is probably a consequence of its burrowing lifestyle rather than evidence of rarity as most temperate species of the genus are difficult to find. Chaban et al report it feeding on the shelled cephalaspid Cylichnatys angusta.
