context_page_description: Vertigo ultimathule is a species of minute, air-breathing land snail, terrestrial pulmonate gastropod molluscs or micromollusks in the family Vertiginidae, the whorl snails.
context_section_description: Vertigo ultimathule is a medium-sized Vertigo, which reaches a height of 2.1–2.2 mm and a diameter of 1.3–1.4 mm, the number of whorls is 4.6–4.7. The shell is almost cylindrical, with marked convex whorls, which are separated by a marked, deep suture. The shape is not distinctly ovoid, as in some other Vertigo-species, and the
  last whorl does not narrow markedly at the base. In side view from left the outer margin of the last whorl forms a blunt angle close to the umbilicus. The aperture is completely toothless or with only a small, delicate, rather deeply set parietal denticle. The mouth-edge is simple and scarcely thickened. The colour of the shell is light yellow – dark yellow-brown. The surface is glossy, with marked, but irregular, rather coarse striation.
