Evaluation of morphology<\/h4>\n<p style=\"text-align: left;\">Published shell morphology is often incomplete, its knowledge is insufficiently used (see Nordsieck 2021).<br \/>\nThe genus taxa have been diagnosed among others by the characters of the inner lamellae endings. These characters have not been considered for the genus taxa out of Japan and Taiwan described in the last decade (except of two); thus, the morphological analysis of these taxa is incomplete. This is of importance, if one tries to classify species with these genus taxa. A good example is\u00a0<i>Oospira ootayoshinarii<\/i>. This species has been classified with nominate\u00a0<i>Oospira<\/i>, but clusters in DNA analysis with\u00a0<i>Formosanella<\/i>\u00a0(see part I). The examination of the inner lamellae endings could give information, where it belongs. Thus, the systematic position of many species described in the last years is uncertain.<br \/>\nIt should be considered that the genus taxa out of Japan and Taiwan can include several groups differing in shell characters, which might be not closely related. <i>Atractophaedusa<\/i>\u00a0consists of two groups, the type group with decollate shell and another group with entire shell.\u00a0<i>Formosana<\/i>\u00a0includes at least three groups: type group, group of\u00a0<i>artifina<\/i>, and group of\u00a0<i>moschina<\/i>\u00a0(small dextral species).\u00a0<i>Serriphaedusa<\/i>\u00a0includes two groups, type group and group of\u00a0<i>draesekei<\/i>; two further groups (<i>Gibbophaedusa<\/i>,\u00a0<i>Altiplica)<\/i>\u00a0have recently been added. Within\u00a0<i>Bathyptychia<\/i>\u00a0three subgenera have been described<i>. Selenophaedusa<\/i>\u00a0consists of five groups: type group, groups of\u00a0<i>diplochilus<\/i>,\u00a0<i>billeti<\/i>,\u00a0<i>bavayi,<\/i>\u00a0and\u00a0<i>spinifera<\/i>.\u00a0<i>Margaritiphaedusa\u00a0<\/i>includes two groups: type group and group of\u00a0<i>ziyuanensis<\/i>,\u00a0<i>Euphaedusa<\/i>\u00a0also two groups: type group and group of\u00a0<i>cylindrella<\/i>. One may not be surprised if these genus taxa do not come out in DNA analysis as monophyletic.<br \/>\nMost publications on genital morphology do not give measurements and exact subdivisions of the male end ducts. So it must be stated that genital morphology of most species is insufficiently known.<\/p>\n<h4 style=\"text-align: left;\">V. Conclusions<\/h4>\n<p style=\"text-align: left;\">From DNA studies (I, II) it is concluded:<br \/>\nCharacter changes used for the shell-based system (III) frequently evolved in parallel.<br \/>\nThus groups with lunella type (included in megagenus\u00a0<i>Hemiphaedusa<\/i>) and groups with\u00a0<i>Phaedusa<\/i>\u00a0type = (ovo)viviparous groups (included in megagenera\u00a0<i>Phaedusa<\/i>\u00a0and\u00a0<i>Euphaedusa<\/i>) comprise non-related evolutionary units.<br \/>\nNot only groups with modified plicae types are different evolutionary units, but also several groups with normal plicae type included in megagenus <i>Oospira<\/i>.<br \/>\nZaptychoids did not evolve separately from similar groups with normal shell size (as assumed in Nordsieck 1998), but evolved within one (<i>Zaptyx<\/i>) clade.<br \/>\nBut \u2013 morphological characters should be evaluated more thoroughly (IV). This should be considered in future DNA studies.<br \/>\nBecause shell characters are often homoplasies and genital characters are similar, higher taxonomic units within Phaedusini can only be characterized by gene sequences. Species or species groups with unknown sequences (at time nearly two thirds of the species, among them the vast majority of species out of Japan and Taiwan) must be provisionally assigned according to morphology and distribution (see Nordsieck 2021).<\/p>\n<h4 style=\"text-align: left;\">References<\/h4>\n<p style=\"text-align: left;\">Motochin, R., Wang, M. &amp; Ueshima, R .

In parts I and II these papers are reported and commented. In part III the shell-based system is summarized. In part IV the evaluation of morphology is discussed. In part V the conclusions are given.
