Acalyptris amazonensis sp. nov.: documentation of another leaf-mining species supplementing the unique but disputable A. latipennata group (Lepidoptera: Nepticulidae)

We describe one new species (Acalyptris amazonensis sp. nov.) from the Amazonian rainforest of Ecuador and provide the first photographic documentation of two other related species also occurring in Ecuador (A. onorei Puplesis & Diškus and A. ecuadoriana Puplesis & Diškus). We briefly discuss diagnostic characters of the A. latipennata species group, which has an outstanding but disputable position within the genus Acalyptris Meyrick.
