The checkered pupfish (Cualac tessellatus) is a species of pupfish endemic to San Luis Potosí in Mexico where it is restricted to the Río Verde and associated waters, including the Media Luna lake (all part of the Pánuco River basin). This species grows to a total length of 8 cm (3.1 in). It is the only known member of its genus.

Editorial summary

This brief starts where responsible research should: with the source description of “Checkered pupfish” as species of pupfish. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 61-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Checkered, pupfish and species can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as species of pupfish. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 28, 2025. The linked authority identifier is Q302252. None of the 0 selected statements returned an explicit reference.

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.
