First Check List of Caddisflies (Insecta: Trichoptera) of Croatia

The Republic of Croatia is placed in the south-east part of Europe. Its territory covers 56000 km2 of land and 32000 km2 of sea. According to the climate and geomorphological particularities three zones can be distinguished: a continental region between the rivers Sava and Drava with continental climate (hot summers and frosty winters), a central highland region with typical mountain climate (short summers, long winters with plenty of snow) and a Mediterranean region with Mediterranean climate (warm and long summers and mild and rainy winters respectively). A geomorphological important part of Croatia is the karst-region (calciferous area) which covers the central-highland and the Mediterranean part. These climate and geomorphological features dominantly influence the hydrological and ecological characteristics of freshwater systems there. Two watersheds can be distinguished: the Black-sea and the Adriatic. Mediterranean region belongs to the Adriatic watersheds. The first data on the Trichoptera fauna of Croatia are known from the second half of the 19th century (Brauer, 1876). Some data were added by Klapálek (1906), Langhoffer (1912, 1915) and Radovanović (1935) in the first half of the 20th century while some more by Marinković-Gospodnetić (1971, 1979) in the second half. Limnological investigations started in the middle of the fifties and were based on larvale determination with contributed only marginally our overall knowledge on the Croatian Trichoptera fauna. Systematic investigation of Trichoptera based on studies of adults started only 15 years ago with filedwork in the National park Plitvice Lakes and later in different our investigation we also included caddisflies collections from museums in Zagreb and Varaždin. By comparing species inventories from neighbouring countries (Bosnia and Herzegovina, Hungary, Serbia, Slovenia) approximately 80 to 85 % of the Croatian species richness have been recorded up to now. Four species in Croatian fauna are endemics: Rhyacophila cabrekenensis, Tinodes andrasi, Chaetopteryx bucari n.sp. and Chaetopteryx uherkovici. Future investigations of caddiflies especially in the continental lowland area and mountains in eastern part of Croatia will provide additional knowledge to current data regarding characteristics of the Trichopteran fauna in Croatia.
