Delias patrua

Delias patrua is recognized as a species and placed in the belladonna comparison group. Its specialist account includes several geographic names with different taxonomic outcomes. Counting those names requires checking whether they are accepted forms, rejected combinations or names reassigned to another species. [1][2]

The specialist comparison emphasizes the absence of a yellow costal patch on the upper hindwing. An absence character needs a clear view of the relevant area: a folded wing or cropped edge cannot demonstrate it. Check the remaining pale marks and outline alongside this feature. [2]

The account includes Chinese localities in Hubei, Yunnan and Sichuan and northern Myanmar, with named Thai and Lao forms. A living Phou Samsoum, Laos, photograph from May 2023 is credited to Steeve Collard. Keep that locality distinct from a generalized mainland Asian range. [2]

The adult comparisons and living photograph do not establish a complete life cycle. A reared patrua sequence would need a determined adult from the same locality. Such evidence could help compare regional forms without relying only on slight differences in adult pattern.

A specific patrua larval host was not established by the checked sources. Finding larvae near a mistletoe should lead to documentation, botanical identification and rearing, rather than an immediate species label. The adult's similar relatives make that final determination important.

The dated Laos photograph supplies one living encounter. It does not establish an annual flight period or a regular feeding routine. Repeated observation with effort recorded would make a behavioural account possible and separate local activity from chance photographic opportunity.

Patrua's nomenclature shows why a list of names is not a species inventory. The specialist account rejects guiyangensis under patrua and reallocates that name within a berinda treatment. A rejected placement belongs in the naming history, not in the count of accepted patrua populations. [2]

Ecological summaries should use the same taxonomic boundaries as the occurrence records. A name reassigned to berinda should not continue supplying patrua habitat or host data merely because an older source used that combination. Review locality and determination before pooling observations.

The specialist page includes a recent Lao form called laotiana and discusses the reassignment of guiyangensis. The present account reports those catalogue details without claiming an unread original description was examined. Harvard's taxon record provides an additional institutional anchor for patrua. [2][3]

No current global threat category was established here. A modern range assessment should exclude records whose former names now identify another taxon, while keeping the correction traceable. Otherwise nomenclatural errors can create apparent range changes with no change in the living populations.

Show the upper hindwing costa clearly to explain the absent yellow patch. A distribution map is useful context but cannot serve as a biological pattern reference. The living Lao photograph and labelled adult plate should retain their exact source determinations.

A reference-based illustration should preserve the upper costal area without adding a yellow patch from a similar jezebel. Keep the locality and regional form caption when known. That small fidelity matters more for identification than a stronger overall decorative contrast.

Keep the enclosure free from physical knocks. Retain reassigned names as historical search terms with their correction noted. The catalogue should distinguish a synonym trail from an accepted identification so a later user does not revive the original labelling error. [4]

Which adult characters separate patrua across its regional forms? What evidence supports the recent Lao form? Which host records are directly linked to checked adults? These questions would extend the account while keeping new geographic names separate from new species.

The specialist treatment provides the adult comparison, nomenclatural notes and attributed Lao photograph. Harvard supplies an institutional taxon record, and the catalogue establishes rank. Follow links to original descriptions when examining new forms; the synthesis itself should not be mistaken for those papers.
