Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    A new Ecuadorian species of the rare Neotropical caddisfly genus Amphoropsyche Holzenthal (Trichoptera, Leptoceridae)
    (Pensoft Publishers, 2016) Holzenthal, Ralph W.; Rios-Touma, Blanca
    A new species of the rare long-horned caddisfly genus Amphoropsyche Holzenthal is described from Ecuador, bringing the number of species known from the genus to 15. All species are very regional in their distributions and known only from very few specimens. The new species, Amphoropsyche real, is similar to a number of previously described species from Colombia (A. ayura, A. cauca, A. flinti, A. quebrada, and A. stellata) and Ecuador (A. napo and A. tandayapa). The males can be distinguished from the others by features of segment X of the male genitalia, especially the prominent midlateral and subapicodorsal spinelike setae. An updated taxonomic key to males of the genus is provided.

    A new species of Amphoropsyche (Trichoptera, Leptoceridae) from Ecuador, with a key to the species in the genus
    (Pensoft Publishers, 2011) Holzenthal, Ralph W.; Rázuri-Gonzales, Luis Ernesto
    A new species of Amphoropsyche Holzenthal is described from Ecuador. It is similar to a group of species with dorsomesal processes on the preanal appendages (i.e., A. woodruffi Flint & Sykora, A. refugia Holzenthal, and A. aragua Holzenthal), but can be distinguished from these and other members of the genus by the short, digitate dorsomesal processes on the preanal appendages and the broad lateral processes of tergum X of the male genitalia. A key to males of the 14 species now known in the genus is presented based on characters of the genitalia.
