Trabecula jeffreysiana is a species of very small sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.[1]
This species has been generally cited in the combinations Chrysallida jeffreysiana or Odostomella jeffreysiana but must be restored to its original combination since Trabecula is currently treated as a valid genus.
This marine species occurs in the Mediterranean Sea and in the Atlantic Ocean off Madeira, the Canary Islands and Mauritania.
