On the Trichoptera of Italy with delineation of incipient sibling species

Lumpers, focussing between gross and molecular morphologies neglecting fine phenomics, highly underestimate biodiversity. The outdated lumper’s attitude fixed in the Distribution Atlas of European Trichoptera (Neu et al. 2018) is revisited some theoretical background why how to delineate phylogenetic-retigenetic incipient species outlined very briefly. We expose adverse effect lumpers order improve by phenomics detection structure local genetic resources, most valuable specific living components, endemics particular ecosystems. In Italian caddisfly fauna we have recorded, treated or revised complex status Plectrocnemia geniculata, Tinodes dives, Diplectrona atra, Rhyacophila praemorsa, R. pubescens, vulgaris, Drusus graecus, D. discolor muelleri, flavipennis, mixtus, spelaeus, alpinus, nebulicola, Limnephilus stigma.
