Why this record matters
“Maoricrypta costata” is worth following because a concise public description often conceals a longer documentary argument. Here, Maoricrypta, costata and species provides the most credible route into that argument.
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 Apr 26, 2026. The linked authority identifier is Q3137851. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1821, 1834 and 2010.
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.
