Triumphis is a genus of sea snails, marine gastropod mollusks in the family Pisaniidae, with historically controversial affinities.
It is found in the tropical eastern Pacific.
[1] Triumphis was historically classified as a member of Buccinidae, but in 1998, Geerat J. Vermeij assigned it to Pseudolividae,[1] However, in 2017, Kantor and colleagues, in their revision of Olivoidea, tentatively assigned Triumphis to Nassariidae,[2] and in 2024, a phylogenetic analysis by Fedosov and colleagues recovered Triumphis as a member of Buccinoidea, the sister taxon to Pisania, the only member of Pisaniidae included in their analysis.
[3] As of December 2024, WoRMS recognizes Triumphis as a member of Pisaniidae;[4] it had previously been included in Pseudolividae.
