Description in Seitz
P. torquatus. male: the band of the forewing is interrupted between the 2. and 3. radial, rarely there is a yellow spot almost filling up the gap; on the under surface of the hindwing a row of red discal spots, of which the last is placed proximally to the last submarginal spot. The female very different from the male, resembling certain Aristolochia-Papilios which occur together with it; wings brown-black, with or without white patches on the forewing; hindwing above with two rows of red spots, the proximal row incomplete, some of the spots merged together in pairs into 2 or 3 large patches. The anal tergite of the male spatulate; the harpe broad, denticulate. Larva shiny, as if polished (which is also the case in all the allied species), mottled with light colour, with irregular pale patch before the middle; the colour of bird-droppings.
Begin with the source’s own compact description: “Papilio torquatus” is species of insect. The dossier treats that line as a proposition to test through Papilio, torquatus 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 22, 2026. The linked authority identifier is Q3019382. None of the 0 selected statements returned an explicit reference.
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.
