Description: A lingulodiniacean genus in which the motile cell has no pronounced spines or horns and the plate formula APC (po, X, cp), 3', 3a, 6'', 6c, 7s, 5'''' (2'''*–6'''*), 1p, 1''''. The 3' plate is small, and positioned along the right side of the apical pore. The cingulum is offset by up to about two cingular widths, and the sulcus is straight (L-type ventral organisation). Thecal plates are thick with circular depressions over the surface of the plates. Cingular and sulcal lists are present. Plate 6'' is 5-sided. Torsion is dextral. Resting cysts when present have a precingular archeopyle, and if processes occur, they are non- sutural in distribution. (Adapted in part from Dodge 1989, 291.)

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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