Sažetak
Subfamily Drusinae is divided into 8 genera: Anomalopterygella, Cryptothrix, Drusus, Ecclisopteryx, Hadimina, Leptodrusus, Metanoea and Monocentra with about 100 described species. The genus with highest diversity is Drusus with 81 described species, whereas Anomalopterygella, Cryptothrix, Leptodrusus, Monocentra and Hadimina are monospecific gernera. Drusinae species usually inhabit springs and crenal sections of mountain streams and rivers with low temperatures and small annual amplitudes. Patchy distributions and isolation of populations are the reasons for the high diversity and high number of endemic species in subfamily Drusinae. Therefore, this subfamily is very interesting for taxonomic, phylogenetic, phylogeographic and evolutionary studies. This year we launched the project: “The Drusinae (Insecta: Trichoptera) in a world of global change: bridging basic and applied research in a highly sensitive aquatic insect group”. Coordinator of the project is Professor Johann Waringer from the University of Vienna. Trichopterologists from several countries are included in the project. They will perform collections in the field (larvae, pupae, adults, longterm water temperature data), descriptions of morphological features of undescribed larvae and undescribed taxa, DNA amplification and sequencing, phylogenetic analyses and species distribution modelling. The project has three main objectives. First, describing of morphological features of unknown larvae of 59 species from subfamily Drusinae and construction of identification keys. Second, to explore the phylogeny of Drusinae in a combined morphological and molecular context. We will test if key innovations (e.g., advanced feeding types) together with Pliocene– Pleistocene climatic change, promoted diversification and speciation. To test this hypothesis we need to increase the number of taxa included in our already established phylogeny of 28 species. We will include morphological data sets of larvae and adults as well as further molecular markers important for the reconstruction of Drusinae phylogeny. Third, analyses of developmental temperature data and species distribution modelling will provide valuable basic information for understanding high mountain biodiversity under two different future climate scenarios. This research project will continue in the next three years.
