Apatania stylata Navás, 1916 TAXO. The taxonomic status and the distribution of A. stylata remain uncertain. While the Distribution Atlas of European Trichoptera (DAET) (Neu et al. 2018; Schmidt-Kloiber et al. 2015) considers it as a single species occurring in both the Pyrenees and Sweden, this discontinuous distribution pattern lacks a clear justification. Thus, experts like Hans Malicky and Peter Wiberg-Larsen have questioned the presence of A. stylata in Sweden (Gullefors 2015). Before that, Svensson and Tjeder (1975) have suggested the existence of a subspecies, A. stylata scandinavica Svensson & Tjeder, 1975, but without providing a formal description, relying solely on Forsslund’s unpublished observations from 1953. In addition, Waringer and Graf (2019) expressed doubts about A. stylata scandinavica being a subspecies of a form primarily found in the Iberian-Macaronesian region and the Pyrenees. On their side, Graf et al. (2026) and Gullefors (2015) considered that A. stylata scandinavica should be considered as a valid species, i. e. A. scandinavica Svensson & Tjeder, 1975 rare and restricted to Eastern Lapland. We thereby suggest that A. stylata should be considered endemic to the Pyrenees and possibly to the Iberian-Macaronesian region, with northern European records from the DAET likely erroneous.
