Diploporaceae (calcareous green algae dasycladales) from the late Visean (Mississippian) of Montagne Noire (southern France)

The Montagne Noire limestones are rich in late Visean (Mississippian) dasycladales and the locality of Cabrières in particular has been famous for over 30 years for the Diploporaceae (metaspondyl dasycladales). New Diploporaceae are described, in order to introduce the necessary nomenclature for future studies. The following new taxa are described: Windsoporella solida, n. sp., W. longirostris n. sp., Cabrieroporinae n. subtrib., Kulikiinae n. subtrib., Borladellinae n. subtrib., Guadiatella heraldica n. sp., Murvielipora n. gen., Murvielipora aretzii n. gen. n. sp., Cabrieroporellopsis n. gen., Cabrieroporellopsis inopinatus n. gen. n. sp. The emended taxa are Windsoporella, W. tulayae, Kulikia and Cabrieropora.
