Shell length to 8.4 mm (up to 16 mm according to Powell 1951); patelliform, high, moderately thick. Apex rolled, located at posterior fourth of total length. Surface white; sculptured with 35 to 45 strong, radial ribs, and minute pits, arranged in rows. Aperture ovate, interior white, margin crenulated. Slit and septum elongated.</p><p>Remarks. Five species of Puncturella were described / mentioned from the sub-Antarctic and Antarctic waters: P. noachina (Linnaeus, 1771), P. conica, P. cognata (Gould, 1852), P. falklandica (Adams, 1866) and P. spirigera Thiele, 1912 . After studying the radula, Powell (1951) concluded that P. noachina and P. conica are two different entities, the former being a boreal species, wrongly previously mentioned from the sub-Antarctic waters. The validity of the other four species deserves further study, due to the discrepant opinions by different authors: Powell (1951) regarded P. conica, P. cognata and P. spirigera as valid species, with P. falklandica as a synonym of the former; alternatively, Reid &amp; Osorio (2000) suggested that “it is possible that only a single species may be involved” among all these taxa, for which they used the name P. conica . This criterion is followed herein.</p></div>	https://treatment.plazi.org/id/03DA87ACFFE8FFB5FF46FDB3FAB82D98	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

Operculum absent.</p><p>Remarks. Thiele (1912) described Proneptunea based on radular characters. Powell (1951) attributed to this genus species with relatively large protoconch of straight sides, and having the operculum with terminal nucleus. The material studied here agrees with the original description of Proneptunea minuta . However, contrary to other species assigned to this genus, the protoconch shows convex whorls and the operculum is absent.</p></div>	https://treatment.plazi.org/id/03DA87ACFFE4FFB9FF46FEB7FB562AB2	Public Domain	No known copyright restrictions apply.

The material studied here is similar to T. perplexa, although differs by having a lower spire. The significance of such differences could not be determined given the poor current state of knowledge of the group.</p></div>	https://treatment.plazi.org/id/03DA87ACFFF1FFACFF46FE4AFB142A8D	Public Domain	No known copyright restrictions apply.
