Type. Conus terebellum Linnaeus, 1758 (Winckworth 1945, p. 144, by subsequent designation)
RegNum Registration Number. 684.
Reference Phylogeny. Figure 3.
Definition. The maximum clade consisting of Terebellum terebellum (Linnaeus, 1758) and all species that share a more recent common ancestor with it than with Seraphs sopitus (Brander, 1766), Paraseraphs tetanus Jung, 1974 or Pseudoterebellum diversiornatum (Eames, 1952).
Diagnosis. The shell is convolute, with an evolute growth pattern. The shell lacks a posterior canal. It is typically smooth, or with greatly reduced sculpture where present, and is widest near the anterior end of the shell. The labrum of the shell is protocyrt, and there is a channeled suture between the whorls. The aperture is long and narrows anteriorly, with a smooth columella. The labium is calloused and extends just above the apex. The basal sinus is present, but shallow.
Composition. Terebellum contains seven species detailed herein, and belongs to the Pseudoterebellinae, but excludes Pseudoterebellum and Paraseraphs.
Remarks. The geological record indicates that Terebellum arose during the beginning of the Neogene, which places the direct ancestor during the Oligocene (Table 8). The earliest record of T. terebellum comes from the early Miocene of Saipan. We propose that the species arose in the Indonesian region and the clade’s ancestor resides there. The clade expanded during the early to mid-Miocene to incorporate a maximum of three species during the Langhian from India to Indonesia. Examples of Terebellum terebellum from the Miocene of Java show little or no variation from the more recent specimens, as does the trace colouration in preserved material (Cox 1948).
A number of Turritellidae Lovén, 1847 have been wrongly assigned to Terebellum: Turritella burdenii Tuomey & Holmes, 1857, Turritella constrictum Emmons, 1858, Turritella etiwanensis Toumey & Holmes, 1857, Turritella exaltata Conrad, 1841, Turritella striatum Tuomey & Holmes, 1857 (Tuomey & Holmes 1857; Emmons 1858; Har- ris 1890; Jung 1974).
