“…The K2P genetic distances among the five specimens are very low (0.2-0.3%) and correspond to genetic distances generally considered as intraspecific distances in cone snails; conversely all the genetic distances with other known cone snail species are large (> 10%) and correspond to genetic distances generally considered as interspecific distances in cone snails (e.g. Duda et al 2008;Puillandre et al 2011). The preliminary analysis using the NJ method suggests that the new species belongs to the Splinoconus clade, as defined in Puillandre et al (2014).…”

Abstract. Based on newly collected material from the Kavieng Lagoon Biodiversity Survey, we describe a new species of cone snail, Conus hughmorrisoni sp. nov., from the vicinity of Kavieng, New Ireland, Papua New Guinea. It closely resembles the New Caledonian C. exiguus and the Philippine C. hanshassi, but differs from these species by having more numerous shoulder tubercles, by the shell's sculpturing and details of the color pattern. We also sequenced a fragment of the mitochondrial COI gene of five specimens collected alive. All possessed very similar sequences (genetic distances < 0.3%), different from all the COI sequences of cone snails available in GenBank (genetic distances > 10%).

“…For the Conoidea, DNA-based taxonomy has frequently resulted in the discovery of new species [31]. More specifically, for the hyperdiverse family Turridae, more than half of the delimited species were not congruent with the morphospecies hypotheses [27].…”

“…Conoidea is one of the most promising animal groups for the discovery of novel pharmacologically active neuropeptides, as exemplified by the development of the first drug from a cone snail conopeptide, ziconotide (Prialt), which is used to alleviate chronic pain in HIV and cancer patients [28]. Traditional taxonomic approaches, based mainly on shell characters, are of little value to identify conoidean species [29], [30], and recent DNA-based taxonomic studies demonstrated that the traditional taxonomic framework of conoideans is largely inadequate [27], [31]–[33]. A recent large-scale survey of species diversity in the Turridae revealed that an exploratory approach using ABGD and Klee diagrams was useful to quickly define numerous PSHs, which were confirmed as valid species with additional evidence [27].…”

A Good Compromise: Rapid and Robust Species Proxies for Inventorying Biodiversity Hotspots Using the Terebridae (Gastropoda: Conoidea)

Devising a reproducible approach for species delimitation of hyperdiverse groups is an ongoing challenge in evolutionary biology. Speciation processes combine modes of passive and adaptive trait divergence requiring an integrative taxonomy approach to accurately generate robust species hypotheses. However, in light of the rapid decline of diversity on Earth, complete integrative approaches may not be practical in certain species-rich environments. As an alternative, we applied a two-step strategy combining ABGD (Automated Barcode Gap Discovery) and Klee diagrams, to balance speed and accuracy in producing primary species hypotheses (PSHs). Specifically, an ABGD/Klee approach was used for species delimitation in the Terebridae, a neurotoxin-producing marine snail family included in the Conoidea. Delimitation of species boundaries is problematic in the Conoidea, as traditional taxonomic approaches are hampered by the high levels of variation, convergence and morphological plasticity of shell characters. We used ABGD to analyze gaps in the distribution of pairwise distances of 454 COI sequences attributed to 87 morphospecies and obtained 98 to 125 Primary Species Hypotheses (PSHs). The PSH partitions were subsequently visualized as a Klee diagram color map, allowing easy detection of the incongruences that were further evaluated individually with two other species delimitation models, General Mixed Yule Coalescent (GMYC) and Poisson Tree Processes (PTP). GMYC and PTP results confirmed the presence of 17 putative cryptic terebrid species in our dataset. The consensus of GMYC, PTP, and ABGD/Klee findings suggest the combination of ABGD and Klee diagrams is an effective approach for rapidly proposing primary species proxies in hyperdiverse groups and a reliable first step for macroscopic biodiversity assessment.

During a broad molecular taxonomic and phylogenetic survey of the gastropod superfamily Conoidea, 80 specimens of several species of the genus Gemmuloborsonia were sequenced for the cytochrome c oxidase subunit I gene. The genus, originally established for fossil species from the Plio-Pleistocene of the Philippines, now includes living species from bathyal depths of the Indo-Pacific Oceans. The molecular data demonstrated the presence of five separate entities, while only four 'morphospecies' could be isolated by visual examination. The two largest groups, representing separate species from the molecular data, were impossible to distinguish with certainty using shell or anatomical characters. To examine shell morphology in more detail the shape of the last whorl was analysed by Fourier analysis, and the Fourier coordinates were used in canonical variate analysis. The majority of the specimens were separated into two groups, but 21.6% of the specimens were impossible to distinguish by morphological characters. One of these two forms was attributed to the known species Gemmuloborsonia moosai Sysoev & Bouchet, 1996, while the other is described as a new species Gemmuloborsonia clandestina. Bathytoma colorata Sysoev & Bouchet, 2001 is transferred to Gemmuloborsonia on the basis of molecular analysis and radular morphology. Another species, represented in our material by a single specimen, remains undescribed.
