In reference to discoidal shape of shell.   Description  Shell(Pl. 1.7; Fig. 21A–D). Broadly conical with low spire, discoid. Rather thin but solid, slightly translucent. Periphery angulate; upper and basal sectors slightly flattened. Umbilicus 10–20% concealed by columellar reflection. Background colour light yellowish brown; peripheral band conspicuous, well developed, moderately broad, clearly visible on last whorl only; sub-sutural band broad, well developed, brown, visible on last whorl only; both bands may blend into each other covering shell with a dark brown tone; outer and inner lip colour white, conspicuously contrasting shell colour. Protoconch 3.1 mmin diameter, comprising about one whorl, with inconspicuous radially elongated pustulations. Teleoconch almost smooth, with very faint, regular axial growth lines. Angle of aperture about 45 degrees; outer lip thin, well rounded, slightly expanded, not or slightly reflected; basal node. Parietal wall of inner lip thin. Average shell size 12.4±0.7 × 20.9± 0.9 mm( Table 1).  Radular and jaw morphology( Fig. 21 E–G). Tooth formula C + 13–15 + 4 + 16–22, with 120 rows of teeth (n = 2). Jaw with c. 10 plates.  Genital morphology( Figs 20, 22). Penis rather straight, tubular, about as long as anterior part of oviduct. Penial sheath very delicate, distally thicker. Length of penial retractor muscle equivalent to about 1/3 of length of penial complex. Penial verge elongately conical, with blunt tip, short, extending about ¼ of length of penial chamber. Inner penial wall entirely covered by densely arranged, very small pustules.
