Dichrorampha leopardana
(Busck, 1906)
Dichrorampha leopardana is a of tortricid in the Tortricidae, Olethreutinae, tribe Grapholitini. It was described by Busck in 1906. The Dichrorampha contains numerous small moths, many of which are associated with alpine and montane . Related species in this genus have been subjects of recent taxonomic revision due to cryptic diversity and long-standing confusion with similar species.

Identification
in the Dichrorampha are small tortricid moths that require careful examination of genitalia and for accurate identification. D. leopardana is distinguished from through dissection and comparison of male and female genitalia structures. Recent integrative taxonomic work on related Dichrorampha species has demonstrated that wing pattern alone is unreliable for species-level identification in this group.

More Details
Taxonomic context
The Dichrorampha has been the focus of recent integrative taxonomic studies combining and molecular data. A 2021 study by Schmid and Huemer described D. velata as new from the Alps, resolving a 180-year-old confusion involving multiple synonymized names. This work highlights the importance of museum collections and careful revision of 'well-known' European fauna.
Research significance
in this exemplify how even extensively studied European Lepidoptera can contain overlooked diversity. The discovery and clarification of Dichrorampha species demonstrates that small, superficially similar may represent distinct species requiring genetic and morphological analysis for proper identification.
