Revision of Neotropical Scythrididae moths and descriptions of 22 new species from Argentina, Chile, and Peru (Lepidoptera, Gelechioidea)
The taxonomy of South American Scythrididae (Lepidoptera: Gelechioidea) is revised, based on external morphology, genitalia, male abdominal segment VIII, and DNA barcodes using genetic distances, BINs, and a tentative molecular phylogeny. Data include both historical and fresh specimens from Argentina, Brazil, Colombia, Chile, Ecuador, Paraguay, and Peru. Thirty-four species are recognised as valid, and the fauna classified in three genera. Type specimens and morphology of all species are described and figured in detail. DNA barcode sequences of the COI gene were successful for 22 species, the average genetic divergence between species being 5.1%. A key to Neotropical Scythrididae species is provided, based on the male genitalia and abdominal segment VIII, which show most and easily accessible interspecific differences.
Our study revealed that the Scythridae fauna of South America is more or less completely unknown. As a result, 22 new species are described, increasing the number of South American Scythrididae species from 13 to 34. All new species are authored by Kari Nupponen (incertae sedis means the genus combination is uncertain and needs further research, country of the type locality is given in parentheses): Rhamphura subdimota sp. nov. (Argentina), R. pozohondaensis sp. nov. (Argentina), R. spiniuncus sp. nov. (Argentina), R. angulisociella sp. nov. incertae sedis (Argentina), R. curvisociella sp. nov. incertae sedis (Argentina), R. tetrafasciella sp. nov. incertae sedis (Argentina), Landryia ankylosauroides sp. nov. incertae sedis (Argentina), L. chilensis sp. nov. incertae sedis (Chile), Scythris directiphallella sp. nov. (Argentina), S. furciphallella sp. nov. (Argentina), S. manchaoensis sp. nov. (Argentina), S. salinasgrandensis sp. nov. (Argentina), S. angustivalvella sp. nov. (Argentina), S. caimancitoensis sp. nov. (Argentina), S. lequetepequensis sp. nov. (Peru), S. sanfriscoensis sp. nov. (Argentina), S. tigrensis sp. nov. (Argentina), S. bicoloristrigella sp. nov. incertae sedis (Argentina), S. saldaitisi sp. nov. incertae sedis (Argentina), S. wikstromi sp. nov. incertae sedis (Argentina), S. andensis sp. nov. incertae sedis (Argentina), S. mendozaensis sp. nov. incertae sedis (Argentina).
The following new combinations are proposed: Scythris depressa Meyrick, 1931 and Scythris dimota Meyrick, 1931 ar

Keeping up-to-date with research can feel impossible, with papers being published faster than you'll ever be able to read them. That's where Researcher comes in: we're simplifying discovery and making important discussions happen. With over 19,000 sources, including peer-reviewed journals, preprints, blogs, universities, podcasts and Live events across 10 research areas, you'll never miss what's important to you. It's like social media, but better. Oh, and we should mention - it's free.
Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform.
