Hello,
as to the discussion on Rapaninae/Thaidinae I refer to the work of S.P.
KOOL, (1993) Phylogenetic analysis of the Rapaninae (Neogastropoda:
Muricidae), Malacologia, 35 (2): 155-259 -
and cite
(page 156): “Of the subgroups of the Muricidae, the group formerly known as
Thaidinae (or as Thaididae) Jousseaume, 1888 (original spelling
 “Thaisidae”), is probably the most problematic and in need of comprehensive
revision. … The family-subfamily controversy is a result of a poor
understanding of genus-level relationships within the Rapaninae and of
relationships between Rapaninae and the other muricid taxa. The generic
allotment for the many rapanine species is highly suspect, as generic
boundaries are usually ill-defined. Many muricid genera of uncertain status
have been placed in Thaididae/nae of authors, resulting in a conglomerate of
disparate taxa. Therefore, Thaididae/nae of authors, as well as other higher
level muricid taxa, are probably para- and/or polyphyletic.”

(page 245): “The newly proposed classification for the taxa examined in this
study is as follows:
MURICOIDEA Rafinesque, 1815
Muricidae Rafinesque, 1815
