For the first time species of caddisflies in the genus Chimarra Stephens 1829 are reported from Malawi. The following new species are described: Chimarra zombaensis, C. flaviseta, C. chichewa, C. circumverta, C. mulanjae, C. psittacus and C. calidopectoris. The descriptions add to the knowledge of Afrotropical diversity in the order Trichoptera.

The paper provides a synoptic key to the genera of final instar European Trichoptera larvae. The most important characters are illustrated by colour photos, with arrows highlighting the diagnostic features. A short descriptive text gives additional information for each decision and guides the reader through the determination process.

Abstract Increased metal concentrations in aquatic habitats come as a result of both anthropogenic and natural sources. Emerging insects that play an indispensable role these environments, transferring resources energy to higher trophic levels terrestrial habitats, may inadvertently also act biovectors for metals other contaminants. This study measured 22 different detected biofilm, life stages...

Three new species of the Rhyacophila scissa Group in the genus Rhyacophila (Trichoptera, Rhyacophilidae), i.e., Rhyacophila matanyii n. sp. from Taiwan (Republic of China), Rhyacophila steinmanni n. sp. and Rhyacophila kisszoltani n. sp. from Nepal are described and illustrated with drawings of the genitalia.

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, Amphoropsyc...
