Original publication and holotype designation: Skuja, H. (1948). Taxonomie des Phytoplanktons einiger Seen in Uppland, Schweden. Symbolae Botanicae Upsalienses 9(3): 1-399, 39 pls.

Description: Colorless, osmotrophic and phagotrophic cells; no ingestion organelle but rhizopodia can be extended from the anterior canal and reservoir; flagella absent; cell rigid or almost so, ovoid, flattened, 40-60 _m long; complex contractile vacuolar system; paramylon present. Affinities uncertain, new cytological and ultrastructural studies desirable; included in Huber-Pestalozzi (1955), Bourrelly (1970) and Starmach (1983). Patterson and Zölffel (1991) suggest a close relationship to Protaspis. Seen only by Skuja in freshwater habitats in Latvia and Sweden.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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