|caption=A simplified version of the phylogeny and relationships of Strombidae according to Simone (2005) With the exception of
Lambis and
Terebellum, the remaining
taxa were previously allocated within the genus
Strombus, including
L. gallus. However, according to Simone, only
Strombus gracilior,
Strombus alatus and
Strombus pugilis, the
type species, remained within
Strombus, as they constituted a distinct group based on at least five
synapomorphies (traits that are shared by two or more
taxa and their
most recent common ancestor).), in this case, included
Aliger gallus (now considered a synonym of
Lobatus gallus) and
Aliger costatus (=
Lobatus costatus), which were thus considered closely related. ==References==
