Abstract

The Mecsek Mountains, with a maximum of 680 m high elevations, are surrounded by low rolling countryside and lowlands. In this area 98 caddisfly species were found. An endemic taxon, Chaetopteryx rugulosa mecsekensis Nógrádi was also found here. Populations of some species have survived far from their continuous distribution area. The only Hungarian population of Plectrocnemia minima Klap. lives here, the population actually being endangered. The occurrence of this species shows zoogeographical connections with the Balkans, while the presence of two other species here (Synagapetus krawanyi Ulmer and Rhyacophila hirticornis McL.) represents their southeastemmost occurrence within their range in the Alpin area. Further eleven species have isolated occurrences as they do not live in the surrounding lowlands and low rolling countryside.
