description: <i>Profunditerebra macclesfieldensis</i> Malcolm, Terryn &amp; Fedosov newspecies (Fig. 12E, F) <i>Type material:</i> Holotype: MNHN IM-2013-61875, 1 lv, 22.4 mm; N Macclesfield Bank; South China Sea, 16 ° 07 'N, 114 ° 23 'E, 161 m (ZhongSha 2015 Stn DW4144). Paratype 1: MNHN IM- 2013-61877, 1 lv, 22.2 mm; type locality. Paratype 2: MNHN IM- 2013-61995, 1 lv, 27.2 mm; type locality. Paratype 3: MNHN IM- 2013-58887, 1 lv, 19.2 mm; New Ireland, 2 ° 26 'S, 149 ° 55 'E, 240–242 m (KAVIENG 2014 Stn DW4485). Paratype 4: 1 dd, 23.1 mm; South China Sea. YT, 200 m. Paratypes 5–7: YT, 3 lv, 20.6–29.5 mm; off Aliguay I., Philippines, dredged at 150–200 m. <i>Zoobank registration:</i> urn:lsid:zoobank.org:act: F1081F38-DB65- 4EDF-B73C-8743D92009A9 <i>Diagnostic nucleotide positions:</i> Table 11. <i>Description:</i> Shell to 30 mm. Protoconch multispiral, 4 translucent amber whorls, small nucleus. Holotype of 12 teleoconch whorls. Teleoconch whorls with straight outline. Subsutural band defined by continuous punctate groove. Axial ribs thin compared with interspaces, gradually becoming more numerous, resulting in about 25 ribs on penultimate whorl of holotype. Ribs only intersected by punctate groove, extended onto flat subsutural band. On last whorl, ribs fade at periphery. No spiral sculpture visible between ribs. Aperture long, creating elongate rounded shape to last whorl. Columella straight, with callus in mature specimens. Colour brown to white with some brown markings. <i>Habitat</i>: Depths of 160– 240 m. <i>Distribution</i>: South China Sea, Philippines and Papua New Guinea. <i>Etymology</i>: Named after the type locality, the Macclesfield Bank in the South China Sea. <i>Remarks:</i> In terms of shell morphology, <i>P. macclesfieldensis</i> n. sp. is most similar to <i>P. anseeuwi</i> (Fig. 12G), <i>Duplicaria duplicata</i> (Fig. 3A) and <i>Punctoterebra teramachii</i> (Fig. 8B). <i>Profunditerebra anseeuwi</i> is the most similar in shell morphology; it has a much shorter columella, creating a cup-shape to the last whorl; its ribs are set at an oblique angle; its colour is white, with broad brown spiral bands between the ribs and dark spots on the subsutural band. <i>Duplicaria duplicata</i> differs in having a paucispiral protoconch of 1.5 whorls, a shorter aperture, and its ribs are broad and closely packed. <i>Punctoterebra teramachii</i> has a much narrower apical angle, the profile of its whorls is more rounded and the subsutural band narrower.
