Source-derived summary

Rapala lankana, the Malabar flash, is a species of lycaenid or blue butterfly found in South India and Sri Lanka. It was first described by Frederic Moore in 1879.

Description

Male: Upperside: Both wings deep purple, almost dull black, but in certain lights the whole of the hindwing and the lower discal area of the forewing glossed with magnificent rich purple. Hindwing with the anal lobe centred with ferruginous.

Underside: Both wings pale ferruginous towards the base, becoming gradually darker towards the margin. Forewing with a somewhat broad straight discal deep ferruginous band from the costa almost reaching the sub-median nervure, its outer edge very even, its inner edge a little irregular. Hindwing with a similar discal band, but posteriorly curved up to the abdominal margin; the anal lobe black, a deep ferruginous spot in the first median interspace on the margin, with some indistinct white speckles between, the discal band also bordered with white on both sides above the anal lobe.

Female: Upperside: Both wings pale violet-brown, marginal line black. Cilia pale ferruginous, at anal angle of hindwing and beyond the tail white. Hindwing with the anal lobe ferruginous, tail black.

Editorial summary

The public source identifies “Rapala lankana” as species of insect. This brief keeps that definition visible, then builds a research path around Rapala, lankana and species.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1879—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Rapala, lankana and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Rapala lankana”, the useful work is to connect “species of insect” to the records capable of establishing context and consequence.

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 May 7, 2024. The linked authority identifier is Q21310186. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1879.

Critical limits

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

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