in penultimate whorl). Texture only interrupted by very few (six) radial growth-rest lines (about one per whorl). Suture deep, indented, underlined by a narrow, low, but conspicuous subsutural keel, starting as a weak structure at the onset of teleoconch and gradually increasing in height until penultimate whorl; in the last whorl shallower. Subsutural keel clearly delimited below by thin incised spiral furrow, briefly overhanging each whorl; thus suture has stepped shape and whorls appear slightly imbricated. Protoconch with 1 1/4 whorl, initially small but greatly increasing, smooth with silky sheen. Aperture (8.7–1.0 mm high,

wide) wide oval, pointed adapically where it forms a small narrow embayment. In lateral view, aperture rises slightly over penultimate whorl, without forming any sinulus. Peristome little thickened and conspicuously reflected, in lateral view slightly sinuous with upper half ortho- to opisthocline. Parietal callus moderately strong, extending over the columella, joining smoothly onto the peristome at the top of its columellar edge, enlarged adapically up to an inconspicuous angular denticle. Umbilicus completely covered by thin, concave callus, adapically narrowing over the parietal callus until reaching the middle of it, and laterally joining peristome through a smooth, well curved bend throughout its columellar margin. Behind aperture and surrounding it on the outside is conspicuous cervical crest, a rather wide (1/5 of shell diameter) semitorus belt, its shape following the curvature of the peristome. Peristome slightly thickened, preceded by narrow but smoothly curved annular depression, rising suddenly but smoothly into very strong cervical crest. Highest part of cervical crest near its posterior third, bulging as rounded raised annular keel. Rear side of cervical crest turns back abruptly, thus making a concave posterior ring. In frontal view, cervical crest protrudes (a bit more so abapically) around peristome, which thus appears as doubled. At suture, cervical crest terminates in nearly semispherical bulge, but reaching columella it submerges under umbilical callus (which is continuous with peristome in this area). No noticeable reflection of cervical crest structure inside the aperture. Peristome and cervical crest, and less so umbilical and parietal callus, stand out through their glossy enamel white color.

It may appear weak science to describe a new species based on very few empty shells. There are, however, two reasons to do so. The first one is theoretical —although sample size is certainly important, its relevance does depend on the range of interspecific variation. In other words, the comparative or explicit classification criteria of taxonomists, intended to predict an underlying phylogeny that is a highly structured object, may be seen as estimators of the cost of incorrect classification, and thus are likely a case of Cover-Hart loss function. In this large class of functions, a small sample turns out to be empirically close to indefinitely larger samples; even a sample size of just one contains at least half the information in an infinite sample (

). In taxonomy, the empirical difference between small and large samples depends on the information content; i.e., the number, discreteness and independence of diagnostic traits allowing correct identification. This does not affect the preceding inequality; instead it means that distinctive taxa may be correctly identified and described on the basis of very few, perhaps only one specimen. Essentially, what matters is the strength of inferences made from the available materials.

Their dispersal abilities are exceedingly limited, so it is likely that the current distributions of these species are largely the result of vicariant events preceding the latest Miocene.
