Source-derived summary

Delias themis is a butterfly in the family Pieridae. It was described by William Chapman Hewitson in 1861. It is found in the Indomalayan realm.

D. themis Hew. has the deep black distal margin more sharply expressed but essentially narrower than in soteira subsp. nov. (55 d), from Luzon, which is also distinguishable beneath by much narrower white circumcellular spots on the forewing.

Editorial summary

Begin with the source’s own compact description: “Delias themis” is species of insect. The dossier treats that line as a proposition to test through Delias, themis and species, not as a finished interpretation.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—1861, 1910—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Delias, themis and species is the immediate research focus.
Editorial analysis

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.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Feb 15, 2026. The linked authority identifier is Q2738489. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1861 and 1910.

Critical limits

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.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
