Description

Diagnosis: Shell with b/l 0.38-0,39, a/l 0,35-0,40, whorls with bluntly angular periphery, median on early whorls, above middle on later ones; sculptured by dense spiral lirae. 19-23 on penultimate whorl, peripheral region crossed on first 3 whorls by weak axial riblets. obsolete thereafter; colour uniform very pale buff: protoconch with axial riblets near termination, breadth 1.20-1.30 mm. Attains 12,0 mm.
Description: Shell claviform (b/l 0,38-0,39, a/l 0,35-0,40), with a moderately produced, obliquely truncate base, suture moderately deep, teleoconch whorls about 5; each whorl bluntly angular, angle median on early whorls, posterior to middle on later ones; shoulder slope slightly concave, no subsutural cord; left side of base of body whorl concave with moderately strong fasciole and shallow false umbilicus. Aperture oblong-ovate, greatest width at about posterior third, siphonal canal wide, parallel-sided, termination very shallowly indented; parietal callus present but depressed and flattened, without a pad or nodule, labium gently sigmoid, columella medially convex, meeting parietal region in an even curve; labrum thin, in side-view convex, with a shallow stromboid notch and moderately shallow, openly U-shaped anal sinus.
Sculptured by dense spiral lirae with weak axial riblets on early whorls; growth-lines give lirae a slightly milled appearance; no varices. Spiral lirae 8-11 on 1st whorl, where they are weak, particularly below suture, 3rd to 5th thread the strongest; penultimate whorl with 19-23. narrower than their intervals, peripheral one not stronger than the others; base of body whorl with 24-26 lirae. closer on rostrum than elsewhere. Axial ribs largely restricted to periphery, opisthocline, widely spaced, arcuate on shoulder slope. 12-13 on 1st whorl, obsolete by end of third whorl. Uniform pale to light orange.
Protoconch globose, of about 1,5 convex whorls, 1st one depressed; smooth except for a series of dense, arcuate axial riblets near termination of last whorl; breadth 1,20-1,30 mm, height 0,95-1,10 mm (b/h 1,18-1.32). Dimensions: 10,8 x 4.2 mm (holotype); 12,0 x 4,6 mm (largest paratype).
