Type specimens.

Holotype: ZMB/Moll no. 109266, fixed by monotypy.

Type locality.

"Station 104 [35°16' südl. Br., 22°267' östl. L., 155 m Tiefe, bei der Agulhasbank]" (South Africa).

Original description.

Eine jedenfalls noch nicht ausgewachsene Schale von derselben Station 104 erinnert durch ihre schlanke Form und die 2 Warzenreihen an die westindische Triphora colon Dall, von der die Anfangswindungen unbekannt sind. Die weiße Schale besteht aus 10 langsam zunehmenden, nicht gewölbten Windungen, deren erste groß und anfangs glatt, dann mit 2 Reifen besetzt ist, die sich auf die beiden nächsten Windungen fortsetzen, um weiterhin in 2 Körnerreihen überzugehen, über der Naht ist der glatte Reifen sichtbar, dem sich die folgende Windung ansetzt. Die letzte Windung ist unten flach und glatt, der Spindelfortsatz kurz, die Mündung klein und viereckig. Höhe 3,3 mm, Durchmesser 0,8 mm.

Translation.

A shell that is definitely not yet adult from the same station 104 [Agulhas Bank] resembles the West-Indian species Triphora colon Dall, because of the slim shape and the two rows of tubercles; the apex of Triphora colon is not known. The white shell has 10 flat whorls which slowly increase in size; the first [protoconch] whorl is big and initially smooth, then sculptured with two keels, which continue on the next two whorls to become two cords with tubercles; above the suture a further smooth cord is visible. The last whorl is on the underside flat and smooth, the siphonal canal is short, the aperture is small and quadrangular. Height 3.3 mm, diameter 0.8 mm.

Diagnosis.

Holotype height 3.4 mm and teleoconch of seven whorls, but the holotype is clearly a subadult specimen. Shell slender, with flat whorls. Teleoconch whorls have two tubercled spiral cords; a fine suprasutural smooth cord is also present. Paucispiral large apex of three whorls: the first whorl is smooth, while the other two bear two strong spiral cords. Colour white, but the specimen is worn, therefore the colour cannot be reliably described. Base and peristome cannot be properly described on the basis of the type material.
