Cryoturris citronella is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.
The length of the shell attains 10.5 mm.
This marine species has a very minute brown tilted protoconch, followed by three trochoid larval whorls. The brilliant yellow spire is markedly shorter than the body whorl, with inflated whorls. The shell contains twelve transverse riblets. There is no varix, and a very faint sutural notch, while the suture is distinct and not appressed. The four larval whorls are prettily marked with transverse concave ripples.
This species occurs in Atlantic waters, ranging from the coast of North Carolina south to the Virgin Islands; in the Caribbean Sea off Cuba in the Gulf of Mexico, the Caribbean Sea and the Lesser Antilles.
