Granigyra tenera is a species of sea snail, a marine gastropod mollusk, unassigned in the superfamily Seguenzioidea.[1]


The shell grows to a height of 1.8 mm. The thin shell is narrowly umbilicated. It is semitransparent, lustreless, with nearly microscopic spiral stride, which are wanting on the base and replaced by a rugose or fretted appearance. The color of the shell is pale yellowish white, with a faint greenish tinge. The four whorls are convex. The suture is very deep. The aperture is circular. The thin peristome is slightly expanded.[2]


This species occurs in the Atlantic Ocean off Portugal.
