Source-derived summary

Pomacea aldersoni is a South American species of freshwater snail with gills and an operculum, an aquatic gastropod mollusc in the family Ampullariidae, the apple snails.

Etymology

P. aldersoni is named after the British conchologist and malacologist E. G. Alderson, who authored a revision of the genus Ampullaria in 1925.

Distribution

The native distribution of P. aldersoni is Ecuador. It was described from thirteen specimens which were collected in Santa Barbara, about 272 km SE. of Quito, in 1939.

Editorial summary

“Pomacea aldersoni” enters the record as species of Gastropoda. Crown Archives preserves that source wording while asking what Pomacea, aldersoni and species can confirm, complicate or overturn.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1925, 1939—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Pomacea, aldersoni and species.
Editorial analysis

Why this record matters

“Pomacea aldersoni” is worth following because a concise public description often conceals a longer documentary argument. Here, Pomacea, aldersoni and species provides the most credible route into that argument.

Evidence profile

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 Q16988359. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1925 and 1939.

Critical limits

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.

How to read it
