Bactrocythara labiosa
species of mollusc
Bactrocythara labiosa is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.
Description
The length of the shell attains 7 mm.
(Original description in Latin) The shell is elongate‑ovate and whitish. It consists of six whorls that show a translucent zone just below the suture. The whorls are moderately convex and slightly angled near their upper part. They are strongly ribbed with oblique longitudinal costae and are crossed by transverse grooves; the grooves are indistinct where they pass over the ribs.
The aperture is narrow and elongate, reaching a length that equals the spire, and it becomes constricted toward the base. The anal notch is distinct. The outer lip is very thick.
The shell is obliquely longitudinally costate, transversely sulcate.

Why this record matters
“Bactrocythara labiosa” is worth following because a concise public description often conceals a longer documentary argument. Here, Bactrocythara, labiosa and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q4840075. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
