Megacraspedus fallax
species of insect

Megacraspedus fallax is a moth of the family Gelechiidae. It is found in France, Spain, Hungary, southern Ukraine, Russia (southern Ural, Volga region, southern Siberia), the Caucasus and from Kazakhstan to north-western China.
The wingspan is 17 mm (0.67 in). The forewings are pale ochreous-yellowish with the markings consisting of shining white edged lines of dark fuscous irroration (speckling). There is a streak from the base just beneath the costa to the costa at two-thirds, with a narrower streak rising out of this along the upper margin of cell to just beneath the apex (the area between this and the preceding wholly irrorated dark fuscous), another along the lower margin of the cell and transverse vein, another along the fold throughout, and irregular lines along veins two to five, seven and eight. The dorsal edge is finely white. The hindwings are whitish.
Begin with the source’s own compact description: “Megacraspedus fallax” is species of insect. The dossier treats that line as a proposition to test through Megacraspedus, fallax 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 Jan 30, 2024. The linked authority identifier is Q13825104. None of the 0 selected statements returned an explicit reference.
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.
How to read it
