Eutorna diaula
species of insect
Eutorna diaula is a moth in the family Depressariidae. It was described by Edward Meyrick in 1906. It is found in Australia, where it has been recorded from Victoria and Tasmania.
The wingspan is 13–14 mm. The forewings are ochreous whitish, densely irrorated with brown and dark fuscous except on the veins, which appear as whitish lines. There is a fine line of blackish scales in the submedian fold from the base to the plical stigma. The stigmata are small and blackish, the plical slightly beyond the first discal and there are some black scales towards the apical part of the costa and termen except at the apex. The hindwings are grey, becoming paler towards the base.
Begin with the source’s own compact description: “Eutorna diaula” is species of insect. The dossier treats that line as a proposition to test through Eutorna, diaula and species, not as a finished interpretation.
Why this record matters
The phrase “species of insect” 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.
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 Mar 20, 2026. The linked authority identifier is Q13630893. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1906.
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.
