“…However, recent studies [53,59] pointed out that conotoxin diversity is correlated to diet breadth more than prey type, revealing the tendency of species with more generalized diets to have more complex venoms and more predation-evoked venom genes. Almost nothing is known about Profundiconus ecology, but the limited data available suggest a worm-hunting diet with at least one species able to prey on fast moving molluscs [24,25]. The venom insulins found in Profundiconus are similar to those of worm- and mollusc-hunting Conus species and have an additional cysteine residue characteristic these species groups.…”

“…Due to the lack of direct observations, Profundiconus ecology and hunting strategy could only be inferred from their radular morphology, which indicates a likely vermivory [24]. Additionally, the find of a small octopus beak in the stomach of a Profundiconus smirnoides Tenorio, 2015 specimen suggested the ability, of at least this species, to prey on cephalopods [24,25].…”

Profundiconus is the most divergent cone snail genus and its unique phylogenetic position, sister to the rest of the family Conidae, makes it a key taxon for examining venom evolution and diversity. Venom gland and foot transcriptomes of Profundiconus cf. vaubani and Profundiconus neocaledonicus were de novo assembled, annotated, and analyzed for differential expression. One hundred and thirty-seven venom components were identified from P. cf. vaubani and 82 from P. neocaledonicus, with only four shared by both species. The majority of the transcript diversity was composed of putative peptides, including conotoxins, profunditoxins, turripeptides, insulin, and prohormone-4. However, there were also a significant percentage of other putative venom components such as chymotrypsin and L-rhamnose-binding lectin. The large majority of conotoxins appeared to be from new gene superfamilies, three of which are highly different from previously reported venom peptide toxins. Their low conotoxin diversity and the type of insulin found suggested that these species, for which no ecological information are available, have a worm or molluscan diet associated with a narrow dietary breadth. Our results indicate that Profundiconus venom is highly distinct from that of other cone snails, and therefore important for examining venom evolution in the Conidae family.

“…Many if not most analyses of molecular diversity of species groups of Conoidea have revealed previously undetected species (e.g. Puillandre, Cruaud, & Kantor, 2010;Fedosov & Puillandre, 2012;Tenorio & Castellin, 2016). In most cases, molecular analyses-and in particular barcoding studies-point to previously unrecognized species, thus providing a basis for re-evaluation of interspecific and intraspecific variability.…”

Crassispira cerithina (Anton, 1838) is a common shallow water conoidean gastropod species, broadly distributed throughout the Indo-West Pacific. It has a distinctive shell morphology and has been referred to in many publications. It is also the first species of its family to have been studied from the viewpoint of toxinology. However, our molecular phylogenetic analysis based on fragments of the COI and 28 S rRNA genes reveals the existence of two closely related distinct species, one of which is described as new (C. scala n. sp.). These two species are sympatric in several regions of the Indo-Pacific-in the Philippines, Papua New Guinea, Vanuatu and New Caledonia. They can be reliably distinguished by shell morphology and thus cannot be considered truly cryptic species. The radula is very similar in both species and does not permit species delimitation. A conchological reappraisal of further material similar to C. cerithina allows us to recognize two additional species, which are described as new (C. procera n. sp. from the Coral Sea and Philippines, and C. aurea n. sp. from Tahiti). These results demonstrate that even 'well-known' and seemingly well defined species may be species complexes and that molecular techniques should be routinely applied to confirm specimen identification, especially as part of resource-consuming studies, such as toxinology.

“…The only exceptions are within Profundiconus, a genus previously recognized as including clearly distinguishable morphospecies, nonetheless separated by very short genetic distances, and even sometimes unrecognizable with the cox1 gene only (Tenorio & Castelin 2016). Indeed, P. kanakinus (Richard, 1983), P. vaubani (Röckel & Moolenbeek, 1995), and the morphospecies P. "white" vaubani are mixed within a single clade; conversely, the species P. neocaledonicus Tenorio & Castelin, 2016 is split into two non-sister clades (they are paraphyletic, one of them being more closely related to the P. smirnoides + P. teramachii clade), while other species (P. smirnoides Tenorio, 2015, P. teramachii (Kuroda, 1956), P. zardoyai Tenorio, 2015) are not statistically supported. The new species C. samadiae sp.…”

“…As a result, a large number of cone snail specimens has now been sequenced, and we can now provide the first comprehensive phylogenetic study of the New Caledonia deep water cone fauna. The study of this material has led to the discovery of several new species in the genus Profundiconus Kuroda, 1956 from this area, which have recently been reported (Tenorio 2015a(Tenorio , 2015bTenorio & Castelin 2016). Now we hereby add another new species to the inventory of the New Caledonia deep water cone fauna, namely Conus (Taranteconus) samadiae sp.…”

The present work reviews the deep-water cone fauna of New Caledonia and its Economic Exclusive Zone. It is based on the material collected for more than 40 years by oceanographic expeditions in the deep waters surrounding New Caledonia, organized by the Muséum national d’histoire naturelle-Paris/ORSTOM, then Institut de Recherche pour le Développement, in the framework of the Tropical Deep-Sea Benthos programme. A total of 2377 lots containing 5113 specimens collected in depths between 100 and 1260 m have been examined. About 770 specimens were collected live, and allowed for radular and DNA studies. A phylogenetic analysis, based on the cox1 gene, of the deep-water cone snail fauna of New Caledonia is presented, along with a detailed, fully illustrated taxonomic account with data on geographic and bathymetric distribution and radular morphology. A total of 76 different species of cone snails were identified among the collected material. Of these, 22 corresponded to typical shallow water species, which were most likely translocated into deeper water, whereas 54 could be considered true components of the deep water (below 100 m) cone snail fauna. Species of the genus Profundiconus represent 22%, whereas those of the genera Conasprella and Conus represent 28% and 50%, respectively. Eleven deep water cone species can be considered as endemic to the New Caledonia EEZ, representing 20.3% of the total. The most abundant species found (more than 400 specimens each) were Conus (Afonsoconus) bruuni, Conasprella (Boucheticonus) alisi, Conasprella (Conasprella) boucheti, and Profundiconus vaubani. The new species Conus (Taranteconus) samadiae sp. nov. is hereby described.
