Description

Previous morphological studies showed that the description of the Cyclotella genus was too general and according to new morphological criteria new genera were established based on both recent and fossil taxa (e.g. Discostella, Handmannia, Puncticulata, Tertiarius). Furthermore, previous molecular biological investigations proved that the Cyclotella genus was not monophyletic. Integrating the above mentioned knowledge the former Cyclotella genus has been split into 4 genera (Cyclotella s.s., Discostella, Tertiarius and Lindavia) on the basis of the position of rimoportula. Our morphological and molecular (rbcL and 18S rDNA) investigations suggested that “Lindavia/Cyclotella ocellata group” could be raised from the Lindavia as a separate genus. Its separative morphological features are the followings: striae unequal in length, central area without areolae. We transferred several Lindavia taxa into the new genus, Pantocsekiella gen. nov.
