Deceptigemmula hastula
species of mollusc
Deceptigemmula hastula is a species of sea snail, a marine gastropod mollusk in the family Turridae, the turrids.
Description
The length of the shell varies between 25 mm and 39 mm.
(Original description by Reeve) The small and slender has an elongate-fusiform shape with a long, almost straight siphonal canal. This species is chiefly characterized by the stout double ridge that encircles each whorl near the suture, and by the central ridge that is formed in place of the slit as the shell advances in growth. The whitish shell is axially marked and diffused with yellowish-brown spots.
(Description by Melvill) An elegant tornate species, with produced siphonal canal, and spiral ribbing somewhat similar to that of Tomopleura nivea (Philippi, 1851), but more regular. The shell is white, tinted yellowish around the upper double carinae of each whorl. Just below the sutures these carinae are spirally deeply punctulate, an item omitted in the original description. As regards the nuclear whorls, the first two are vitreous, globular, smooth, and shining, the two next, also vitreous, but spirally nodulous.
Distribution
This marine species occurs in the Persian Gulf, the Arabian Sea and off the Philippines

Why this record matters
“Deceptigemmula hastula” is worth following because a concise public description often conceals a longer documentary argument. Here, Deceptigemmula, hastula 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 May 19, 2026. The linked authority identifier is Q3724112. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1851 and 2024.
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.
