Jahn, R. & Kusber, W.-H. 2004: Algae of the Ehrenberg collection – 1. Typification of 32 names of diatom taxa described by C. G. Ehrenberg.
Willdenowia 34: 577-595.
The present paper is the first in a series of papers typifying names of algae taxa, which Ehrenberg described as new, and illustrating the type specimens. In this paper, 32 diatom names from 18 genera in current use are typified, 58 infrageneric diatom names are evaluated. Diploneis atmosphaerica and Odontella rhomboides are validated as new names. Seven specimens are designated as the types for names of the genera Brebissonia, Gomphonema, Microtabella, Petrodictyon, Raphoneis, Rhopalodia, Zygoceros. Four names are attached to specimens that are either not available or not identifiable because of girdle band view or unrecognizable drawings. Three names are heterotypic synonyms of taxa described earlier. In addition, this paper presents an update on the organization of the Ehrenberg collection after it has been modernized through funds of the AlgaTerra project.
