Description (holotype): Shell of moderate size, to 42 mm. Protoconch of 4 narrow, conical whorls with small nucleus. Teleoconch of 12 whorls; teleoconch whorl outline convex constricted abapically at the suture. Subsutural groove represented by weak indentation on early whorls becoming sharper groove cutting through the ribs on mature whorls. Sculpture of strong slightly convex narrow axial ribs on subsutural band aligned with those on succeeding portion of whorls, varying significantly between specimens in spacing, and in number from 18 to 25 (20 ribs on penultimate whorl). No spiral sculpture in interspaces except for striae on base below periphery. Last whorl cup-shaped, becoming more elongate on mature specimens. Aperture wide with slight callus; columella straight with 2 folds. Colour off-white with tinges of yellow or pink with shiny white columella.
Habitat: Depths of 350– 600 m.
Distribution: Papua New Guinea, Solomon Islands and Taiwan.
Etymology: Named after its deep-water habitat in Papua New Guinea.
Remarks: The only sequenced specimen of P. papuaprofundi n. sp. with intact protoconch was designated as the holotype. It is notably smaller than the sequenced paratypes, which reach shell lengths of 42 mm. The larger specimens demonstrate the increased curvature of ribs and increased number and density of ribs to 25 on the penultimate whorl. Profunditerebra papuaprofundi n. sp. is phylogenetically closest to P. orientalis and P. anseeuwi . Profunditerebra anseeuwi has a weaker subsutural groove, straight and oblique ribs and a mottled colour pattern. Profunditerebra orientalis has more axial ribs, a mottled colour pattern, and a sculpture of ribs and spiral cords creating nodes at their intersections. Specimens of P. papuaprofundi n. sp. with more numerous curving ribs are similar to Maculauger cinctella and Terebra textilis ( Salvador & Pickering, 2017). However, M. cinctella ( Fig. 12C View Figure 12 ) has a shorter protoconch of 2.5 whorls, a much narrower noded subsutural band and many spiral striae within the interspaces between the ribs. In turn, T. textilis ( Fig. 12D View Figure 12 ) differs in having a spiral groove defined by deep punctations or partially cutting the ribs, and has several spiral striae in the interspaces between the ribs.
