This is one of the most common of the tropical members of the genus. It is white with black spots as in P. solidula, but the shell is more slender and the black spots are usually separated into three wide bands on the body whorl by three white spiral lines. Widespread throughout the Indo-West Pacific. Solidula affinis A. Adams, 1855 is probably an earlier name for this species but the name Pupa affinis had already been used for landsnails [Rossmaessler, 1839; Aradas & Maggiore, 1843] so is unavailable.

Note added May 2009: In southeastern Australia this species has commonly been identified as Pupa fumata (Reeve, 1865), but the shell colouration falls within the variation found elsewhere in P. strigosa, so I consider it to be another synonym.

See P. solidulaand Japonacteon suturalis.
