A revision of Leucotrichia (Trichoptera, Hydroptilidae) is provided, including a generic diagnosis, illustrations, a key, and descriptions of males. A total of 43 species are treated, 13 described as new: Leucotrichiaangelinae sp. n. (Venezuela), Leucotrichiadenticulata sp. n. (Mexico), Leucotrichiadianeae sp. n (Costa Rica), Leucotrichiafulminea sp. n. (Ecuador), Leucotrichiahispida sp. n. (Co...

The Tapee River is one of the most important rivers in southern Thailand. The river crisscrosses from Khao Luang National Park, Nakhon Si Thammarat province to Surat Thani province and flows to the Thai Gulf. To study the biodiversity and distribution of Trichoptera species along the Tapee River, insects were collected by light trapping every 3 months from April 2004−February 2005. The results ...

In addition to a list of valid names and synonyms, as provided by the Trichoptera World Checklist, access to the primary literature itself is essential for research in Trichoptera taxonomy and systematics. To improve access to bibliographic information, we established the Trichoptera Literature Database, http://www.trichopteralit.umn.edu, a bibliographic database of over 8,500 citations of lite...

Ten new Neotropical species of Chimarra are described in the subgenera Chimarra, Chimarrita, and Otarrha. New species in the subgenus Chimarra include, in the Chimarra ortiziana group: Chimarra calorisp. n. (southeastern Brazil) and Chimarra onchyrhinasp. n. (Venezuela); in the Chimarra picea group: Chimarra inchoatasp. n. (Venezuela), Chimarra nicehuhsp. n. (Venezuela), and Chimarra sunimasp. ...

Aiming to elucidate whether large-scale dispersal factors or environmental species sorting prevail in determining patterns of Trichoptera species composition in mountain lakes, we analyzed the distribution and assembly of the most common Trichoptera (Plectrocnemia laetabilis, Polycentropus flavomaculatus, Drusus rectus, Annitella pyrenaea, and Mystacides azurea) in the mountain lakes of the Pyr...

A new species, Rhyacophila langkawia sp. n., belonging to the R. curvata Group sensu Schmid (1970) is described. The samples provide also material of the previously undescribed species cited by Schmid (1970) as R. schmidi, a nomen nudum; this species is described as R. schmidirossia sp. n., also in the R. curvata Group. Other sampled species were Rhyacophila curvata Morton, recorded for the fir...

BACKGROUND Aquatic insects and other freshwater animals are some of the most threatened forms of life on Earth. Caddisflies (Trichoptera) are highly biodiverse in the Neotropics and occupy a wide variety of freshwater habitats. In Andean countries, including Ecuador, knowledge of the aquatic biota is limited, and there is a great need for baseline data on the species found in these countries. H...

Two new species of Xiphocentron (Trichoptera: Xiphocentronidae) from Northeastern Brazil are diagnosed, described, and illustrated. Xiphocentron (Antillotrichia) kamakan n. sp. has inferior appendages each with a shape discontinuity (twist) between the first and second articles of inferior appendage, similar to that found in X. (Antillotrichia) rhamnes Schmid 1982, X. (Antillotrichia) serestus ...

The Trichoptera (caddisflies) is a holometabolous insect order with 14,300 described species forming the second most species-rich monophyletic group of animals in freshwater. Hitherto, there is no mitochondrial genome reported of this order. Herein, we describe the complete mitochondrial (mt) genome of a caddisfly species, Eubasilissa regina (McLachlan, 1871). A phylogenomic analysis was carrie...

Abstract The loss of aquatic biodiversity in tropical streams SE Asia is evident due to increasing anthropogenic activities. Therefore, there a necessity for immediate and feasible conservation plans. Effective planning depends on successful application surrogate groups. However, progress this approach hindered by the paucity relevant reports based cross-taxon congruence analysis. In study, we ...
