“…The organisation of these adaptive structures is processed frequently in post-mating prezygotic copulatory mechanisms like cryptic female choice with over 25 known mechanisms (Eberhard 2010) including gametic incompatibilities. The divergence of speciation traits, like any kind of divergences, is initiated stochastically by random environmental effects, but stabilised on molecular level by complex adaptive and integrative mechanisms (Oláh et al 2017, Oláh & Oláh 2017.…”

“…Segment X (XI) is most produced and the genitalia primitively comprise 7 pairs of appendages: (1) dorsomesal lobes of segment IX; branches on segment X (XI): (2) preanal appendages; (3) external branches; (4) internal or intermediate branches; (5) inferior branches; (6) subanal plate; (7) inferior appendages on segment IX. These structures are variously present or absent in different genera; some of them often lost through specialization by simplification that could be an inherent complexity increase (Oláh et al 2017). Complexity could arise, not only by incremental addition but by incremental subtraction in the Apataniidae, Uenoidae families and in the Dicosmoecinae subfamily of the limnophiloid Polyphorae.…”

“…On the other hand, the variations could be real existing ontic/ontological inherent modalities (Oláh 2018). Neutral, non-adaptive traits are exposed to stochastic population effects and could be highly variable, but adaptive, non-neutral speciation traits under elaborated network of protective mechanisms are stable (Oláh & Oláh, 2017).…”

The discovery of the new Agaphylax genus with unique paramere organisation has initiated our lineage sorting of tribes by parameres in the Limnephilinae subfamily applying the principles and procedures of fine phenomics in order to establish 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 organ is a speciation supertrait. This adaptive trait is directly involved in the processes of reproductive isolation and diverging as subtle 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 of the 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 and appears as a character with tribe ranking potential. To open a wider perspective, a systemic relational analysis is required in the future including other adaptive or neutral character transformation series, due to the burden of taxonomic incongruences grounded 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 genitalic characters additional to parameres for a future analysis of the potential of character combinations. Limnephilinae subfamily is composed of Limnephilini, Chilostigmatini, Chaetopterygini, Stenophylacini and Hesperophylacini tribes and here we established the new Agaphylacini tribe. Based on parameres we have delineated taxa in lineage sorting and described two new genera:

“…However, if these divergences are non-neutral, non-random product of adaptive processes in sexual selection even their subtle shape differences are steady and stable. Their stability is due to the underlying very complex adaptive genomic processes organised and maintained by several integrative as well as protective mechanisms like reduced recombination, linkage disequilibrium, selective sweeps and genetic hitchhiking (Oláh & Oláh 2017). At incipient Drosophila species well differntiated by genetic markers, the empirically almost indiscernible slight divergences in aedeagus curvatures are detectable only by geometric morphometrics.…”

The caddisfly materials collected by Hungarian zoologists during 25 collecting trips between the years of 1970 and 2016 in the Korean Peninsula was identified and compared when required with Eastern Palaearctic relatives. The appendicular genital terminology was adopted and applied to several representatives of Polyphorae taxa. We identified 95 caddisfly species, including 5 new records for the Korean Peninsula:
