(with its type species, P. borgei Lemmerm.), Ark. Bot. 2 (1904): 134.</p><p>Description: Thecate, phototrophic, free-living primarily freshwater dinophytes. Kofoidian plate formula: ≤4’, ≤2a, ≤7’’, 6c, 5s, 5’’’, 2’’’’, apical pore complex present ( Parvodinium, Peridiniopsis) or absent ( Palatinus). Plate surface smooth through granulate, but never with ridges forming areolae, hypotheca variously spinose through smooth. Chloroplast lobes radiating from a central pyrenoid; eyespot and peduncle microtubules present. Dividing or ecdysing cells exiting the theca through the antapical area. n≈40 (Holt &amp; Pfiester 1982).</p><p>The Peridiniopsidaceae, fam. nov., are taxonomically distinct and may include some 15 species occurring in temperate through tropical freshwater habitats around the world (frequently encountered species are Palatinus apiculatus, Parvodinium africanum, P. centenniale, P. deflandrei, P. goslaviense, P. inconspicuum, P. lubieniense, P. umbonatum and Peridiniopsis borgei). They can be delimited from other peridinialean families based on a combination of traits (Tab. 1) including the preferred freshwater versus the otherwise primarily marine environment. They are further distinct from the other genuine freshwater family, Peridiniaceae, because of the presence of not more than two (versus three) intercalary plates and six (versus five) cingular plates. Ultrastructural traits such as the presence of peduncle microtubules and chloroplast lobes radiating from a central pyrenoid may provide further evidence for the distinctiveness of the new family. Last but not least, the Peridiniopsidaceae, fam. nov., constitute a monophyletic lineage of the Peridiniales distinct from the Peridiniaceae and other peridinialean lineages in molecular phylogenetics (Fig. 1). Future research will enlighten the systematic positions of Glochidinium, Staszicella, Thompsodinium and many other dinophytes in either of Peridiniaceae, Peridiniopsidaeceae, fam. nov., or other (established or even more new) families in the Peridiniales . Family circumscriptions would have to be adjusted if applicable.</p></div>	https://treatment.plazi.org/id/03D787B01239FFBCFF14FF1AFE25FC79	Public Domain	No known copyright restrictions apply.
