Source-derived summary

The roughhead shiner (Notropis semperasper) is a species of freshwater ray-finned fish beloinging to the family Leuciscidae, the shiners, daces and minnows.

It is found only in the upper James River drainage, Virginia, USA.

In March 2022, the Center for Biological Diversity petitioned the U.S. Fish and Wildlife Service to list the roughhead shiner as endangered.

Editorial summary

Begin with the source’s own compact description: “Roughhead shiner” is species of fish. The dossier treats that line as a proposition to test through Roughhead, shiner 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—2022—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Roughhead, shiner 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 Q2247128. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2022.

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.
