Valve face weakly convex, mantle rounded, distinctly indented at base where it meets expanded hyaline valve margin with raised border. Valve covered with false pseudoloculi, basal layer with poroid areolae, radially aligned. Poroid areolae occluded by two types of vela, mostly cribra with occasional specialised pore present. Rimoportulae single (rarely two), submarginal or at foot of elevation. Valve interior with uninterrupted radial rows of poroid areolae. Valvocopula distinct, with broad pars interior and inner row of elongate pores.

Origin of description: this description is from the original publication; it may have been modified slightly.

Numbers of names and species: There are 5 species names in the database at present, of which 5 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
