The caddisflies of the Chaetopteryx rugulosa group are endemics to the western Balkan and to a few nearby areas. All species and subspecies of the group have very restriced ranges, from the south-eastern Alps to the Southern Carpathians. Classic taxonomic studies suggested that the group is undergoing an accelerated speciation throug rapid radiation into isolated habitats. The central area of the radiation is located on the western Balkan. This is a karstic region, where springs are rare but permanent and they are generally isolated by impenetrable dry areas. The survival and diversification of organisms was most probably driven by climate and geology-related cclimate and geology drives speciation through rapid radiations into new enviroments.hanges in the availability of spring habitats. This unique setup makes the C. rugulosa group an ideal model system to study how climate and geology drives speciation through rapid radiations into new enviroments. We intend to validate the actual taxonomy, and to reconstruct the history of the group by comparing multilocus nucleotide sequence data (mtCOI, wingless, EF-1α) for all the 6 species, 4 subspecies and 2 hybridizing populations. Our results mostly confirmed the actual taxonomy of the group, but we also found additional, geographically confined cryptic diversity, and paraphyly of several subtaxa. Based on the depth of disjunctions we conclude that both geological and climatic changes contribute to the ongoing speciation of the species group.
