Tylostega mesodora
species of insect
Tylostega mesodora is a moth in the family Crambidae. It was described by Edward Meyrick in 1894. It is found on Borneo.
The wingspan is about 19 mm. The forewings are fuscous, the inner margin is suffused with ochreous towards the middle. There is a suffused pale ochreous, orange tinged, streak along the costa. The lines are dark fuscous, forming blackish spots on the costa. There is a blackish discal mark and a slender orange hindmarginal streak, preceded by a series of blackish spots. The hindwings are marked as the forewings, but there is a broad ochreous-white antemedial band.
Begin with the source’s own compact description: “Tylostega mesodora” is species of insect. The dossier treats that line as a proposition to test through Tylostega, mesodora 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 Jun 11, 2026. The linked authority identifier is Q20720976. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1894.
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.
