Resumo
New material collected in Albian and Cenomanian strata from Brazil helps us to better understand the structure of a poorly known dasycladacean alga, Holosporella nkossaensis P. Masse, in Bull Centr Rech Explor-Prod elf aquitaine, 19: 301-317, 1995: each of its fertile laterals, which are regularly arranged in verticils along the cylindrical algal thallus, consists of a distally inXated primary bearing two vesicular ampullae in terminal position. These traits are not known in representatives of the genus Holosporella Pia, 1930 nor in any genera described to date. On this basis, we introduce the new genus Brasiliporella with Brasiliporella nkossaensis emend. nov. comb. as its typespecies. We also discuss the systematic aYnity of the new taxon: it is ascribed to the Tribe Batophoreae, and in a broader manner the current paleontological 'interpretation of the concept' (in French: 'acception') of the Order Dasycladales, with the creation of two new families and accordingly with the emendation of two other families. © Springer-Verlag Berlin Heidelberg 2012.
