Pseudorhaphitoma informis is a small sea snail, a marine gastropod mollusk in the family Mangeliidae.

(Original description) The small, rather solid shell has an ovate-elongate shape and is broader and shorter than usual.

Its colour is a uniform pale buff externally, stained with orange inside the aperture.

The spirals are fine, even, and close threads, which become coarser and more widely spaced on the aperture.

[2] This marine genus occurs in the Gulf of Carpentaria and off Queensland and New South Wales, Australia
