Description
Puncturella conica (d´Orbigny, 1841)
Fig. 2B
Rimula conica d´Orbigny, 1841: 471, pl. 78, figs. 10, 11
Puncturella noachina — Melvill & Standen, 1912: 118 (non Linnaeus, 1771)
Puncturella conica — Powell, 1951: 86, fig. G2 (radula); Castellanos, 1982a: 41
Examined material. 119 sh. (MACN-In 40661).
Description. 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.
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 & 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.
