Source-derived summary

The smallscale yellowfin (Plagiognathops microlepis) is a species of freshwater ray-finned fish belonging to the family Xenocyprididae, the East Asian minnows or sharpbellies. This species is found from the southern part of the Amur drainage systems, including the Ussuri and Lake Khanka, and along the major river drainages of China south to the Xi River in southwestern China and northern Viet Nam. The smallscale yellowfin has a maximum published total length of 70 cm (28 in). This species was first formally described in 1872 as Plagiognathus jelskii by the Polish naturalist and physician Benedykt Dybowski with its type locality given as Lake Khanka and the Ussuri River. Dybowski's genus name was objectively invalid as it was preoccupied by Plagiognathus Fieber, 1858 in Hemiptera and in 1907 Lev Berg proposed the genus name Plagiognathops for this taxon.

Editorial summary

Begin with the source’s own compact description: “Smallscale yellowfin” is species of fish. The dossier treats that line as a proposition to test through Smallscale, yellowfin 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—1872, 1858, 1907—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Smallscale, yellowfin and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of fish” 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 May 21, 2026. The linked authority identifier is Q2567492. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1872, 1858 and 1907.

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

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