Figure 2 in Maxwell and Rymer (2021). Definition. The maximum clade consisting of Terebellum terebellum Linnaeus, 1758 and all species that share a more recent common ancestor with it than with Strombus pugilis Linnaeus, 1758 , Tibia fusus ( Linnaeus,1758 ) , Struthiolaria papulosa (Martyn, 1784) or Aporrhais pespelecani ( Linnaeus, 1758 ) . Diagnosis. The shell is typically long and narrow, with the last whorl extending over much of the earlier whorls. The stromboidal notch is poorly developed or absent. Composition. The clade contains two subfamilies, Pseudoterebellinae with three genera, Seraphsinae with three genera, and the genus Mauryna , the content of which is detailed herein. It explicitly excludes the sister taxa contained within Rostellariidae and Strombidae . Remarks. This family was defined as containing two distinct groups: the involute Seraphs Montfort, 1810 and relatives, and the evolute Terebellum Röding, 1798 and Paraseraphs Jung, 1974 ( Jung 1974 ) complexes. The relationships contained within the definition have been supported by a morphological study by Maxwell et al. (2019) and with the use of molecular data ( Irwin et al. 2021 ).
