Sažetak
Subterranean habitats are inhabited by numerous specially adapted taxa, which typically have limited distribution ranges on both specific and generic level. They are generally bound to narrow geographical areas, yet there are exceptional lineages exhibiting large and disjunct distributions. One of the cases is the subterranean collembolan genus Verhoeffiella that occurs in five remote karstic regions, from 150 to 1000 km apart (Dinarides, Jakupica in North Macedonia, South-eastern Calcareous Alps, Southern Catalonia and Cordillera Cantabrica). We tested the monophyly of Verhoeffiella and explored its relationship with the surface and presumably related genus Heteromurus. Further, using species delimitation methods and time divergence estimation, we explored hidden diversity and temporal diversification. Our results show that the genera Verhoeffiella and Heteromurus are paraphyletic, with lineages of Verhoeffiella intermixed with lineages of Heteromurus nitidus. Discovery of highly diversified subterranean group with closely related surface relatives represents an exceptional case within the subterranean fauna of temperate regions. Species delimitation methods revealed increased molecular divergence and overlooked diversity within both genera. The highest increase was noted in Verhoeffiella populations in the Dinarides, where the number of MOTUs (N=79) exceeded the number of described species by eight times. When put on the time scale, most of cladogenetic events coincide with Messinian salinity crisis (5.96-5.33 MA), while speciation events with the age of Pleistocene (2.5 MA - 11.7 k years ago), indicating that paleogeographic changes could be one of the main triggers of diversification within Verhoeffiella.
