Latrogastropoda is a clade of gastropods, considered a superorder, [1] in the subclass Caenogastropoda. It was originally proposed in 2000 by Frank Riedel to unite the predominantly predatory "higher" caenogastropod groups. [2] Latrogastropoda includes both the order Neogastropoda and some taxa classified in the paraphyletic order Littorinimorpha. [3] Latrogastropoda is equivalent to the "siphonate group" of caenogastropods recognized by Ponder and colleagues in 2008. [4] [3] [5] The non-neogastropod latrogastropods are broadly equivalent to the Neomesogastropoda. [1] The name Strombogastropoda was proposed by Simone in 2011 for a clade uniting stromboids with neogastropods and their close relatives, [6] and is equivalent to Ponder and colleagues' concept of Latrogastropoda. [7]
Fossils recognizable as latrogastropods due to their protoconch are known as far back as the Aptian stage of the Cretaceous. [10] Tonnoidea and Neogastropoda are potentially descendants of the Purpurinidae, which date to the Triassic. [11] The earliest known cypraeids date to the Tithonian stage of the Jurassic. [12]
