Taxonomic remark Created by Eisenack, 1958, for thin-walled "leiospheres" different from those of the types species of his previous genus Leiosphaera, which was recognised to be a synonym of Tasmanites. Retained in Acritarcha rather than Prasinophyta at this time following Hannah et al., 2000, who state: "Hannah et al. (1998) followed the suggestion of Guy-Ohlsen (1996) and placed Leiosphaeridia in the prasinophyte algae. Tyson (1995) noted that that the position of Leiosphaeridia amongst the prasinophytes is problematic. Leiospheres are smooth walled (Lindgren, 1981, 1982), and lack the morphologic features (pits, pores, ridges, laminated or layered walls) that allow Tasmanites, Cymatiosphaera, Pterospermella and other genera to be classified with confidence as prasinophytes (Tappan, 1980). Because of the uncertainty in their taxonomic position leiospheres are here retained in the Acritarcha." Sergeev et al., 2012 placeconsider at least 2 species (L. jacutica and L. minutissima) to be prokaryotes (Cyanobacteria). [details]
