Abstract [en]

The discovery of the new Agaphylax genus with unique paramere organisation has initiated our lineage sorting oftribes by parameres in the Limnephilinae subfamily applying the principles and procedures of fine phenomics in order toestablish transformation series of the polarized plesiomorphy-apomorphy character states for each limnephiline genera.According to the extraordinary high diversity the paramere that is the stimulatory and titillating structure of the phallic organis a speciation supertrait. This adaptive trait is directly involved in the processes of reproductive isolation and diverging assubtle initial split of lineages producing the incipient sibling species in the recent past of contemporary speciation processes.Contrary, the drastic divergence of the Agaphylax plated paramere is much older, similarly to the many-spined parameres ofthe Hesperophylacini tribe. It has been initiated by drastic combined and synchronous external and internal stochastic effects,processed in ancestral sexual integrative adaptation as well as organised and fixed in older and deeper coalescence events andappears as a character with tribe ranking potential. To open a wider perspective, a systemic relational analysis is required inthe future including other adaptive or neutral character transformation series, due to the burden of taxonomic incongruencesgrounded by chimerism in stochastic genetic reticulation. Traits of species are mixed products coming from various sources.Only character combinations can and ought to be analysed in terms how to classify taxa. We have polarized eight genitaliccharacters additional to parameres for a future analysis of the potential of character combinations.Limnephilinae subfamily is composed of Limnephilini, Chilostigmatini, Chaetopterygini, Stenophylacini and Hesperophylacinitribes and here we established the new Agaphylacini tribe. Based on parameres we have delineated taxa in lineagesorting and described two new genera: Fogophylax gen. nov., Simaphylax gen. nov. and fourteen new species: Anaboliaalsoja, A. hepehupa, Asynarchus kimaros, Limnephilus kerekes, L. maghrebensis, L. oblos, Homophylax beges, H. coros,Chaetopteroides plackovicensis, C. rilaensis, Allogamus ketpar, Platyphylax beshkovi, Pycnopsyche letova and P. telea spp.nov. The by-product of this survey is a world atlas of paramere drawings for the entire Limnephilinae subfamily.
