Description: Medium-sized (30-60 µm) spherical to slightly asymmetric biflagellated cells with a posteriorly directed longitudinal flagellum and a slightly displaced transverse flagellum. Cell covering with cellulosic cell wall, plate formula Po,X,4', 3a, 7", 6c, 4s, 5"',2"". The apical intercalary plates 2a and 3a are separated by plate 3' in contrast to Scrippsiella Balech ex Loeblich III. Also the apical pore complex is distinctive, like a chamber.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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