A new Ecuadorian species of the rare Neotropical caddisfly genus Amphoropsyche Holzenthal (Trichoptera, Leptoceridae).

ABSTRACT: 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 (Amphoropsyche ayura, Amphoropsyche cauca, Amphoropsyche flinti, Amphoropsyche quebrada, and Amphoropsyche stellata) and Ecuador (Amphoropsyche napo and Amphoropsyche 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.

Two new species of the rare Neotropical caddisfly genus Amphoropsyche Holzenthal (Trichoptera, Leptoceridae).

Project description:Two new species in the rare, endemic Neotropical caddisfly genus Amphoropsyche Holzenthal, 1985 are described from Ecuador (A. carchisp. n.) and Peru (A. matsigenkasp. n.) bringing to 17 the number of species known in the genus. Almost all species are known from only a few individuals and from even fewer localities. The new species belong to a group of 10 other species that have tergum X in the male genitalia divided into a mesal process and a pair of lateral processes. Amphoropsyche carchi can be separated from those species by the rounded mesal concavity, the short mesobasal lobe, and the short 2nd article of the inferior appendage, while A. matsigenka can be diagnosed by the very slender and straight inferior appendage, which bears a pair of spine-like mesoventral projections. We also present a new record for Amphoropsyche tandayapa Holzenthal & Rázuri-Gonzales, 2011, from Ecuador, previously known only from the male holotype.

New species of the endemic Neotropical caddisfly genus Contulma from the Andes of Ecuador (Trichoptera: Anomalopsychidae).

Project description:The genus Contulma Flint (Trichoptera: Anomalopsychidae) is composed mostly of regionally endemic species occurring above 2,000 m, with a few more widespread species and some that are found at lower elevations. Adults of three new species of Contulma are described and illustrated from the Andes of Ecuador, Contulma lina, new species, Contulma quito, new species, and Contulma sangay, new species. These species are similar to previously described species from the region, including C. paluguillensis, C. nevada, and C. lancelolata. New provincial records are provided for C. bacula, C. cataracta, and C. echinata. Contulma duffi Oláh, 2016 is considered a junior, subjective synonym of C. penai, Holzenthal & Flint, 1995. Also, we provide an identification key to males of the 30 Contulma species now known.

Systematics of the Neotropical caddisfly genus Notidobiella Schmid (Trichoptera, Sericostomatidae), with the description of 3 new species.

Project description:Three new species of Notidobiella Schmid (Insecta: Trichoptera) are described from South America: Notidobiella amazonianasp. n. (Brazil), Notidobiella brasilianasp. n. (Brazil), and Notidobiella ecuadorensissp. n. (Ecuador). In addition, the 3 previously described species in the genus, Notidobiella chacayana Schmid, Notidobiella inermis Flint, and Notidobiella parallelipipeda Schmid, all endemic to southern Chile, are redescribed and illustrated, including the females of each species for the first time, and a key to males of the species in the genus is provided. The occurrence of Notidobiella in Brazil and Ecuador represents a significant extension of the range of the genus beyond southern Chile where it previously was thought to be endemic. The biogeography of Sericostomatidae and other austral South American Trichoptera is reviewed. The presence of the family in South America may not be part of a "transantarctic" exchange, but instead may represent an earlier occurence in the region. The distribution of Notidobiella in tropical South America likely represents recent dispersal from southern South America to the north.

Fourteen new species of Oecetis McLachlan, 1877 (Trichoptera: Leptoceridae) from the Neotropical region.

Project description:BackgroundThe caddisfly genus Oecetis currently contains 534 valid species. Its larval stages are found in freshwaters around the world. The adults can be distinguished from other Leptoceridae by the unbranched forewing M vein and the exceptionally long maxillary palps. In the Neotropical region, 55 species of Oecetis have been recorded and most of them can be placed in one of the six species groups known from this biogeographical region: the avara-, falicia-, inconspicua-, punctata-, punctipennis-, and testacea-groups. More than 50% of the known diversity of Neotropical Oecetis has been described in the past 40 years. Here, we describe an additional 14 new species of Oecetis to further document the diversity of this genus in the Neotropical region.MethodsThe descriptions and illustrations presented here are based on male specimens. Specimens were collected with Malaise traps or ultraviolet light traps. They were preserved in alcohol or pinned as stated in material examined section. Specimens had their genitalia prepared in 85% lactic acid to better observe internal characters and illustrations were aided by the use of a microscope with drawing tube attached.Results and discussionThis study raises the number of species of Oecetis in the Neotropics from 55 to 69. Eight of the new species presented here could not be reliably placed in one of the known species groups (Oecetis acuticlasper n. sp., Oecetis flinti n. sp., Oecetis carinata n. sp., Oecetis cassicoleata n. sp., Oecetis blahniki n. sp., Oecetis gibbosa n. sp., Oecetis licina n. sp., and Oecetis pertica n. sp.). The others are placed in the punctata-group (Oecetis bidigitata n. sp., Oecetis quasipunctata n. sp.), testacea-group (Oecetis plenuspinosa n. sp.), and falicia-group (Oecetis calori n. sp., Oecetis hastapulla n. sp., Oecetis machaera n. sp.). Most of the diagnostic characters rely on structures of the inferior appendages and phallic apparatus, and the shape of tergum X.

A new species of Amphoropsyche (Trichoptera, Leptoceridae) from Ecuador, with a key to the species in the genus.

Project description: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., Amphoropsyche woodruffi Flint & Sykora, Amphoropsyche refugia Holzenthal, and Amphoropsyche 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.
