Source-derived summary

Amiga is a monotypic butterfly genus in the family Nymphalidae erected by Shinichi Nakahara, Keith R. Willmott and Marianne Espeland in 2019. Amiga arnaca, formerly of the genus Chloreuptychia, is the only species in the genus Amiga. In 2019, Nakahara et al. described this new genus after molecular phylogenetic research showed it was not closely related to the other species of Chloreuptychia.

Amiga arnaca is found from southern Mexico through most of Central and South America to southern Brazil, and is common in rain and cloud forests. The larvae feed on grasses, including Eleusine, Ichnanthus, Lasiacis, Oplismenus, and Paspalum.

Editorial summary

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

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—2019—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Amiga, arnaca and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of butterflies” 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

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 9, 2026. The linked authority identifier is Q61396467. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2019.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. 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.
