Drilliola loprestiana
species of mollusc
Drilliola loprestiana is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.
Taxonomy
Figueira & Absalão (2010) used the name Drilliola pulchella (Verrill, 1880) for the species generally known as Drilliola loprestiana. They illustrated as "holotype Drilliola loprestiana (Calcara, 1841), MAL-1930, photo courtesy of Museo di Zoologia 'P. Doderlein', Palermo University", a specimen with a paucispiral protoconch, which is Drilliola emendata (Monterosato, 1872). This is questionable, because when establishing the genus Drilliola, Locard (1897: 213) provided notes from Monterosato (who then had purchased the Brugnone collection with Calcara's types), in which Drilliola loprestiana was clearly understood in the current acception (i.e. the species with a brown, multispiral protoconch). Most fortunately, ICZN art. 74.6. does not allow after year 2000 the fixation of a lectotype by inference of a "holotype", so this has no nomenclatural effect.
Description
The size of an adult shell varies between 4 mm and 8.7 mm. The shell contains seven whorls with revolving carinae, the interstices longitudinally striate.
The public source identifies “Drilliola loprestiana” as species of mollusc. This brief keeps that definition visible, then builds a research path around Drilliola, loprestiana and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Drilliola loprestiana”, the useful work is to connect “species of mollusc” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q3138534. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2010, 1880, 1841 and 1930.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
