AI Article Synopsis

  • The Cymbellaaffinis / Cymbellatumidula / Cymbellaturgidula species complex faces taxonomic challenges due to its diverse morphology and absence of clear type designations.
  • Fifteen taxa names, across five species, were reassessed for their taxonomic status and designated lectotypes based on original material.
  • The study utilized light and electron microscopy, leading to four new combinations for reclassifying infraspecific taxa within the complex.

Article Abstract

Specimens belonging to the Cymbellaaffinis / Cymbellatumidula / Cymbellaturgidula species complex have many taxonomic problems, due to their high morphological variability and lack of type designations. Fifteen taxon names of this complex, distributed in five species, were re-evaluated concerning their taxonomic status, and lectotypified based on original material. In addition to light microscopy, some material was analyzed by electron microscopy. Four new combinations are proposed in order to reposition infraspecific taxa.
