Type species Murex senticosus Linnaeus, 1758 , by original designation (Tropical Indo-West Pacific). Remarks The Photinae were recently the subject of a profound taxonomic revision ( Galindo et al . 2016 ). Molecular data prove that all species belonging to Phos Montfort, 1810 represent a monophyletic group occuring exclusively in the Indo-West Pacific, distinct from the Carribean Antillophos Woodring, 1928 (see Galindo et al . 2016: 343 , fig. 1, 345, fig. 2, 348, fig. 3). It is typical that genera within Nassariidae are geographically restricted clades, while the biogeographic range of genera is usually broader in Buccinidae . The generic separation within Photinae based on sculpture and protoconch morphology, as discussed by Fraussen & Poppe (2005: 76–77 , 81–82), no longer holds. As a result, Phos senticosus , with a smooth protoconch, is congeneric with other Indo-West Pacific species that have a characteristically sculptured protoconch and that were formerly placed in Antillophos . For a discussion about the taxonomic positions of Phos and Antillophos within Nassariidae , we refer to Galindo et al . (2016) .
