Mixobrycon
genus of fishes
Mixobrycon is a monospecific genus of freshwater ray-finned fish belonging to the suborder Characoidei within the order Characiformes, the characins. The only species in the genus is Mixobrycon ribeiroi, a species endemic to Paraguay, where it is found in the Paraguay River basin. This taxon has not been assigned to a particular family within the Characoidei and is considered to be incertae sedis, i.e. its taxonomic affinities are, as yet, unclear.
Named in honor of Alípio de Miranda Ribeiro (1874-1939) a Brazilian ichthyologist-herpetologist.

Begin with the source’s own compact description: “Mixobrycon” is genus of fishes. The dossier treats that line as a proposition to test through Mixobrycon, genus and fishes, not as a finished interpretation.
Why this record matters
The phrase “genus of fishes” 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.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q19757853. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1874, 1939 and 2011.
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.
