Source-derived summary

Hypostomus margaritifer is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the upper and middle Paraná River basin. The species reaches 33 cm (13 in) in total length and is believed to be a facultative air-breather. It is known to be syntopic with other loricariid species in the genus Hypostomus, including Hypostomus ancistroides, H. denticulatus, H. heraldoi, H. iheringii, and H. regani.

Hypostomus margaritifer appears in the aquarium trade, where it is typically referred to as the yellow-spotted hypostomus.

Editorial summary

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

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 89-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Hypostomus, margaritifer 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

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 23, 2024. The linked authority identifier is Q5862426. None of the 0 selected statements returned an explicit reference.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
