Holotype species: Strombomonas verrucosa (E.Daday) Deflandre

Original publication and holotype designation: Deflandre, G. (1930). Strombomonas nouveau genere d'euglénacées (Trachelomonas Ehr. pro parte). Archiv für Protistenkunde 69: 551-614.

Taxonomic status: currently recognized as a distinct genus.

Gender: This genus name is currently treated as feminine.

Most recent taxonomic treatment adopted: Cavalier-Smith, T. (2016). Higher classification and phylogeny of Euglenozoa. European Journal of Protistology 56: 250–276, 2 figs.

Description: Solitary, free-swimming, green, Euglena-like cells, mostly 25-50 _ 15-35 _m, completely enclosed in an envelope which tapers gradually to the apical pore, with no sharply defined neck or collar; the mature envelope usually remains colorless or pale yellow, smooth or rough, non-brittle and without ornamentation (no pores, punctae, spines or ridges); other characters as Trachelomonas; numerous species, varieties and forms differ in size and shape of envelope; chloroplasts discoid or flat with inwardly projecting pyrenoids. The genus was established by Deflandre (1930) for species and varieties previously placed in Trachelomonas; boundaries between the 2 genera remain imprecise. Strombomonas has been reviewed by Conrad and Van Meel (1952) who divided it into 4 sections on envelope characters. Freshwater; cosmopolitan.

Numbers of names and species: There are 116 species names in the database at present, as well as 115 infraspecific names. Of the species names, 88 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.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
