Description. Shell very small (to 7.9 mm in total length), glossy, partially translucent, broadly fusiform; with convex whorls, sutures appressed; whorls number about 8, the last approximately 58 % of the total length; aperture short and relatively wide. Protoconch of 2 translucent, relatively large, smooth round whorls, the first not immersed in the second. Axial sculpture of slightly opisthocline ribs suture-to-suture on spire whorls, to anterior fasciole on last. Ribs are recurved on the shoulder, have their peripheries slightly below mid-whorl, and number 10–11 on the penultimate, 7 on the last whorl to the varix. Varix like a swollen rib, about ⅓-turn from edge of outer lip. Spiral sculpture of 6 ridges on the anterior fasciole. Microsculpture of faint intercostal grooves on last and penultimate whorls. Sulcus absent. Prior positions of the anal sinus indicated by recurved ribs and growth striae, and absence of intercostal spiral grooves. Outer lip thin, translucent, somewhat swollen bubble-like, with two thin, strengthening axial folds near the edge. Edge of lip forms a low arc from anal sinus to anterior canal; stromboid notch shallow. Anal sinus a deep notch with a round apex adjacent to suture on shoulder, sides slightly convergent; inner rim flared out. Inner lip emarginated, narrow and erect on end of anterior canal, recumbent elsewhere, widest on upper canal then narrows to a weak parietal lobe on parietal lobe. Anterior canal moderately long, wide, open, slightly twisted to the right when viewed ventrally, notched; anterior fasciole not swollen. Color translucent white with ...
