Desmodesmus (Chodat) S.S.An, T.& E.Hegewald, 1999
Holotype species: Scenedesmus quadricauda (Turpin) Brébisson
Original publication and holotype designation: An, S.S., Friedl, T. & Hegewald, E. (1999). Phylogenetic relationships of Scenedesmus and Scenedesmus-like coccoid green algae as inferred from IT-2 rDNA sequence comparisons. Plant Biology 1: 418-428, 23 figs, 1 table.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as masculine.
Most recent taxonomic treatment adopted: Hegewald, E., Wolf, M., Keller, A. Friedl, T. & Krienitz, L. (2010). ITS2 sequence-structure phylogeny in the Scenedesmaceae with special reference to Coelastrum (Chlorophyta, Chlorophyceae), including the new genera Comasiella and Pectinodesmus. Phycologia 49(4): 325-335.
Vanormelingen et al. (2007: 378) note that this used to be the most species-rich subgenus of Scenedesmus, but it was given genus status based on 18S and ITS2 rDNA phylogenies (Kessler et al. 1997, An et al. 1999, Van Hannen et al. 2002. The genus is also morphologically well defined but species delimitation is problematic. - (6 Nov 2007) - Wendy Guiry
Numbers of names and species: There are 68 species names in the database at present, as well as 47 infraspecific names. Of the species names, 65 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..
Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.
