Abstract

The genera Windsoporella mamet & rudloff emend. VaChard and Eovelebitella VaChard, are revised. Several species previously described in the literature are considered to be included in the genus Windsoporella emend.: W. radiata mamet & rudloff, Queenslandella jenkinsi mamet & roux, ‘Dasycladacée indéterminée’ mamet & roux, Diplopora tulayae Chanton-GüVenç, Velebitella pareyni mamet & roux, and Eovelebitella sp. sensu lyS, StamPli & Jenny. In addition, three other new species are described from carbonate rocks in Ireland, England, Morocco and Spain, W. clogrenensis n. sp., W. adamuzensis n. sp., and W.? but tevantensis n. sp. The last mentioned species might represent a transitional form between Windsoporella and Eovelebitella. The genus Eovelebitella seems to be limited to E. occitanica VaChard and similar species and subspecies, described here as E. occitanica marbellensis n. subsp. and E. betica n. sp. Other species previously considered by some authors as Eovelebitella, i. e., E. robertsii mamet & roux, Diplopora pusilla KoChanSKy & heraK, and D. constantini PonCet are no longer included in the genus. E. rob ertsii is designated as the type-species of the new genus Austreovelebitella n. gen. The genus Japhetella mamet & roux seems to be a nomen invalidum because its type-species is clearly an Eovelebitella, although the single existing illustration of this taxon is a Windsoporella.

晚古生代浅壳藻Windsoporella和Eovelebitella的修正和新种

属Windsoporella mamet & rudloff修订。对VaChard和evelebitella VaChard进行了修订。以前在文献中描述的几个物种被认为包括在Windsoporella修订属中。: W. radiata mamet & rudloff, Queenslandella jenkinsi mamet & roux， ' dasycladacemoe indacemterminacemoe ' mamet & roux, Diplopora tulayae Chanton-GüVenç， Velebitella pareyni mamet & roux，以及Eovelebitella sp. sensu lyys, StamPli & Jenny。此外，还在爱尔兰、英格兰、摩洛哥和西班牙的碳酸盐岩中发现了3个新种:W. clogrenensis n. sp.、W. adamuzensis n. sp.和W.?但是- tevantensis n. sp.最后提到的物种可能代表了Windsoporella和Eovelebitella之间的过渡形式。Eovelebitella属似乎仅限于E. occitanica VaChard和类似的种和亚种，这里描述为E. occitanica marbellensis n. subsp。以前被一些作者认为是Eovelebitella的其他物种，即e. robertsii mamet & roux, Diplopora pusilla KoChanSKy & heraK和D. constantini PonCet不再包括在该属中。Japhetella mamet & roux属似乎是一个nomen invalidum，因为它的模式种显然是一个Eovelebitella，尽管这个分类单元的单一现存例证是一个Windsoporella。

期刊介绍： Section B of Palaeontographica publishes contributions to palaeobotany, i.e. papers on morphological traits, systematics and phylogenetic features of plants as well as papers on palaeoclimatology and palynogeography. Especially worth mentioning are the comprehensive monographs published in Palaeontographica B on specific floras or plant groups. Often palaeoclimatic or stratigraphic problems are clarified by resorting to palaeobotanical data published in Section B of Palaeontographica. Throughout the last decades, numerous objects important to palaeophytology have been found in many places all over the world. As Palaeontographica publishes papers on floras on any parts of the world to report world-wide research, contributions in German, English and French have been published since the beginning of the journal, today English language publications are preferred. Palaeontographica B is of interest to palaeobotanists, palynologists, palaeoclimatologists, stratigraphers and the libraries of all institutions engaging in such research.
