An assessment of Raphitoma and allied genera (Neogastropoda: Raphitomidae)

The systematics of several Eastern Atlantic conoidean species, traditionally ascribed to the genus Raphitoma 1847, are revised on the basis of DNA sequence data from three gene regions (cytochrome c oxidase subunit I, 16S rRNA and 12S rRNA). We assign genus ranking to three major lineages (Raphitoma, Cyrillic Kobel'. 1605 and Leufroyia Moniesosato. 18841 and suggest that two West African species belong in the subgenus Daphnella (Paradaphne) Laseron, 1954. A new classification, based on molecular systematics and critical study of morphology, is provided for all Eastern Atlantic and Mediterranean species that are currently ascribed to Raphitoma s.l. The genus Clathromangelia Monturosa to, 1881 is confirmed as belonging to Raphitomidae. Phylogenetic relationships and genetic distances suggest that Raphitoma maculosa Hoismer, 2016 and R. obese Hoisaitur, 2016 may be divergent morphotypes of R. bicolor (Risso 1826) and Cyrillia aequalis (Jeffreys, 1867), respectively.
