Abstract

In the present paper on the Western European Trichoptera we revise or overview the Platyphylax and Simaphylax limnephiline genera, as well as establish and/or overview the Drusus chapmani, Chaetopteryx gessneri and C. gonospina species complexes based on the principles and procedures of our fine phenomics. Having collected a new Drusus chrysotus (Rambur, 1842) specimen we have reconfirmed its delineation from its eastern sibling species Drusus lapos Oláh, 2017. By the paraproct, the Drusus spelaeus siblings in the Drusus mixtus species group are related to the Drusus siveci species complex in the Drusus discolor species group. Our discovery of a population of Drusus spelaeus with paramere structure similar to that of the Drusus discolor species group indicates further the importance of chimeric processes in species integrative organisation. Due to contradictory drawings published we have re-examined and redescribed the female of Drusus spelaeus. After surveying the recent taxonomic history of the Allogamus auricollis species subgroup we have raised the subspecies status to species rank of Allogamus auricollis bauerii (Kolenati, 1859); A. brauerii stat. nov. Chaetopteryx gessneri tomaszewski Moretti, 1991 was elevated to species rank: Ch. tomaszewski stat. nov. and Chaetopteryx kimera Oláh & Vinçon, 2021, a rather unique chimeric species having several character states of different origin was transferred to Consorophylax genus: C. kimera (Oláh & Vinçon, 2021) comb. nov. Furthermore, 17 new species were described: Wormaldia ariega, W. ligurica, W. maritima, Drusus alethes, D. italiano, Chaetopteryx tompula, C. cantabrica, C. decampsi, C. pyrenaica, Consorophylax cairos, C. lagoverde, C. livek, C. seolan, Platyphylax vinconi, Simaphylax coppai, S. andorricus and S. ariegeus spp. nov. Among them, ten were collected in France, five in Italy, one in Slovenia and one in Spain. Moreover, we report for the first time Potamophylax spinulifer Moretti, 1994 and Beraeamyia gudrunae Malicky, 2002 from France and Simaphylax altuspyrenaicus from Spain.
