''Vaceuchelus foveolatus'' is a species of sea snail, a marine gastropod mollusk in the family Chilodontidae.〔Bouchet, P. (2012). ''Vaceuchelus foveolatus'' (A. Adams, 1853).

==Description==
The height of the shell reaches 8 mm. The small, solid, white, very minutely perforated shell has a globose-conic shape. The spire is short. The four whorls are convex and encircled by strong spiral ribs. The interstices between them are deeply, coarsely pitted by the prominence of strong, regular, longitudinal lamellae, continuous over the spirals. The penultimate and next earlier whorls have 3 spirals (the subsutural one sometimes subobsolete). The outer lip is inserted upon the fourth. On the body whorl near the aperture there are 7, but sometimes more, by reason of the interpolation of one or two interstitial riblets on the upper surface. Two or three submedian ribs are generally more prominent. The sutures are canaliculate. The aperture is rounded. The columella is slightly concave, rather wide and flat, but not toothed at base. The umbilical perforation is minute.〔(Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia )〕
This is a very distinct little shell, with coarsely latticed sculpture.
