Source-derived summary

Margarya oxytropoides is a species of large operculate freshwater snail, an aquatic gastropod mollusc in the family Viviparidae, the river snails.

Distribution

The distribution of Margarya francheti includes Dian Lake, Lugu Lake, and small lakes around Zhaotong in Yunnan Province, China.

Description

Zhang et al. (2015) provided details about the shell and about the radula.

Editorial summary

Begin with the source’s own compact description: “Margarya oxytropoides” is species of mollusc. The dossier treats that line as a proposition to test through Margarya, oxytropoides and species, not as a finished interpretation.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—2015—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Margarya, oxytropoides and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of mollusc” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 29, 2024. The linked authority identifier is Q20817875. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2015.

Critical limits

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

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
