Sphaleromantis Pascher, 1910

Holotype species: Sphaleromantis ochracea (Ehrenberg) Pascher

Original publication and holotype designation: Pascher, A. (1910). Chrysomonaden aus dem Hirschberger Grossteiche: Untersuchungen über die Flora des Hirschberger Grossteiches. I. Teil. Monographien und Abhandlungen zur Internationale Revue der gesamten Hydrobiologie und Hydrographie 1: 1-66.

Description: Cells solitary, free-swimming, somewhat metabolic, strongly flattened when seen from the side and triangular, square to subspherical or ovate in face view. In one species with a raised transparent wing or ridge extending medially from apex to base on the broad side of the cell. Only one long flagellum visible with the light microscope, inserted at the anterior end of the cell. Ultrastructural features have not been described. Chloroplasts two, stigma usually one (in one species apparently lacking). Contractile vacuoles usually 2, located at the anterior end of the cell. Reproduction not described. Stomatocysts unknown. All species rarely observed, mostly in plankton of freshwater lakes and ponds, two species in brackish waters. Sphaleromantis -like cells which are unflattened and possessing organic scales on body and flagella have been referred to the recently established genus Chrysolepidomonas (Peters and Andersen 1993). Sphaleromantis also resembles Boekelovia in the light microscope, which however is biflagellate (Nicolai and Baas-Becking 1934) and apparently belongs to the Prymnesiophyceae (Barclay and others 1991).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
