Mangelia semiassa is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.[1]
This is a taxon inquirendum.
It was first described by Augustus Addison Gould in 1860. The shell of this species typically reaches a length of about 8 mm and a diameter of 3 mm.[2]
(Original description in Latin) The shell is rhomboid-fusiform, thick, and shiny. It is whitish but livid anteriorly. The shell is inscribed with 8 ribs and very fine revolving striae. There are 6 angular whorls, and the suture is impressed. The aperture is piriform and is half of the total length, tapering to a point anteriorly. The outer lip is simple and thickened, and the sinus is barely noticeable. The columella is straight and livid.[3]
