Here are some scans of the Hawaiian Facelinella semidecora to compare with Bernard's Phidiana anulifera. The species is relatively common on some reefs around Oahu, usually at depths of 2 meters or less.

It's good to see some clearer photos of this species. Although there are similarities I lean towards the view that these are distinct species.
