Genus Neoterebra View in CoL new genus

( Fig. 9 View Figure 9 F–H)

Type species: Terebra specillata Hinds, 1844 View in CoL .

Zoobank registration: urn:lsid:zoobank.org:act:68993F36-2AD1-4DDE-A853-8832B4A9EE30

Definition: Includes all species included in clade E4 of Modica et al. (2019) and those that show a combination of conchological, anatomical and distribution characteristics closely comparable with Neoterebra specillata View in CoL or any genetically proven member of the clade.

Diagnosis: Diagnostic nucleotide combinations in Table 9 View Table 9 .

Shell: Small to medium-sized (<60 mm); uniformly creamy-white to light brown or with pattern of brown blotches; pointed multispiral or paucispiral protoconch, 1.5 to about 3 whorls. Axial sculpture of orthocline or arcuate ribs, forming axially elongated subsutural nodules on well-defined band. Spiral sculpture from weak striae in interspaces between ribs to distinct cords, overriding ribs, often forming nodes at intersection or on lower portion of ribs. Last whorl typically abruptly constricted to siphonal canal. Canal clearly separated from shell base, bearing pronounced fasciole.

Anatomy: Radula, proboscis, venom gland typically absent. Radula, when present, of hypodermic type. Salivary glands typically present. Accessory proboscis structure absent.

Distribution: Tropical East Pacific, Caribbean, off Brazil; intertidal to upper bathyal depths, but typically shallow water.

Remarks: Shallow-water species of Neoterebra differ from their congeners from deep water of Brazil and the Caribbean, being larger at maturity and sharing characteristic sculpture of strong axial ribs that form elevated, sometimes axially elongated nodules on the subsutural band. Caribbean species have a weaker subsutural band; those from deep water commonly lack a recognizable subsutural band and display a fine cancellate pattern of narrow axial riblets, intersected by spiral cords of equal strength. Although the affinity of Panamic and Caribbean species is suggested by the analysis of COI, further studies are needed to document relationships and delineate major groupings within the genus.

Etymology: The name is a combination of neo (Latin: new) and Terebra , referring to the fact that species of this new genus only occur in the New World, constituting the majority of the terebrid fauna in the region.
