Monodonta lugubris Lamarck, 1822

Monodonta lugubris is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.

Monodonta lugubris is considered by CLEMAM a synonym of Phorcus lineatus (da Costa, 1778). Henry Pilsbry, on the other hand, considered already in 1889 that the name lineatus of Da Costa, used until that time by many authors, should be considered inadmissible on account of the failure of that author to use generic in combination with his specific names. To add to the confusion, the website gastropods.com considers Monodonta lugubris a synonym of Osilinus lineatus lineatus Costa, E.M. da, 1778, while WoRMS considers Osilinus lineatus a synonym of Phorcus lineatus.
