TYPE MATERIAL. — Syntype. New Caledonia • MNHN-IM-2000-1400; 1 specimen; from type locality. ORIGINAL DESCRIPTION. — T. sinistrorsa, elongato-conica, apice acuta, nitidissima, alba, fusco inaequaliter tincta, circa basin praesertim et suturas, ad apicem verò pallidè violacea. Anfractus circa 15, angusti, lentè accrescentes, liris duabus aequalibus, pellucidè granulosis, gemmis inter se junctis, ornati, sutura vix profunda (plerumque fusco tincta in inferioribus anfractibus) discreti. Penultimus subconvexus, liris 2-3 granulosis cingulatus. Ultimus convexus, liris 5 minoribus, gemmiferis, cinctus, basi depressus, in dorsali parte (circa 2/3 decursûs partent), propè suturam canali tubifero, recurvo munitus, indè tubulatus, tenuis, liris 3 graniferis striisque elevatis, latè clathratus, ad aperturam evadens. Canalis basalis mediocris, obliquus, recurvus, omninò clausus. Apertura parva, obliquè ovata, tubularis, peristomate continuo. Long. 7 mill.; diam. mar. 2.50 mill. Hab. Insula Lifou. Vidi 8 specimina, à R. P. Goubin, S. M., collecta. TRANSLATION OF THE LATIN TEXT. — Sinistral shell, elongated and conical, acute apex, bright, white, irregularly coloured in brown, above all near the base and the suture, while towards the apex it is coloured in light violet. Whorls are about 15, narrow, slowly growing, with two equal spiral cords bearing transparent granules and adorned by paired tubercles, separated by a barely deep suture (mostly coloured in brown in the inferior whorls). Penultimate whorl is slightly convex, with two or three granulated spiral cords. Convex last whorl, with five minor tubercled spiral cords, depressed at the base, dorsally (for about 2/3 of the whorl) with a curved tubular channel near the suture, from here it appears tubular, extensively cancellated by three slender granulated spiral cords which extend over the aperture and are crossed by elevated spiral cords. Medium-sized siphon, oblique, cured, completely closed. Small aperture, obliquely ovate, tubular, peristome continuous. Length 7 mm; maximum diameter 2.50 mm. Locality: Lifou Island. I saw 8 specimens collected by R. P. Goubin. DIAGNOSIS. — Shell conical with flat sides. Syntype 5.0 mm high. Teleoconch of c. 11 whorls. Two spiral cords present. Both cords with tubercles at the intersection with prosocline axial ribs. At the suture, a fine smooth thread present. Posterior sinus well developed and protruding as a short canal. Base with two additional spiral cords of which the first tubercled and the second smooth. First six teleoconch whorls white, lower teleoconch whorls white with a brown line between the spiral cords. Base brown.Published as part of Albano, Paolo G., Franco, Davide Di, Azzarone, Michele, J., Piet A., Bakker & Sabelli, Bruno, 2023, Review of the types of Indo-Pacific Triphoridae (Mollusca, Gastropoda) in the Muséum national d'Histoire naturelle, Paris, pp. 13-106 in Zoosystema 45 (2) on pages 37-38, DOI: 10.5252/zoosystema2023v45a2, http://zenodo.org/record/756974
