Original publication and holotype designation: Jovanovska, E., Cvetkoska, A., Tofilovska, S., Ognjanova-Rumenova, N. & Levkov, Z. (2016). Description of a new fossil diatom genus, Cribrionella gen. nov. (Bacillariophyta) from Quaternary sediments of Lake Ohrid. Phytotaxa 252(1): 13-42, 61 figs.

Fossil: This is a genus of fossil species, or a genus with a fossil type species, or a genus the type species of which was originally described as a fossil.

Description: Cells solitary, circular in valve face view. Central area flat, variable in size and shape. Valve central part enclosed with central lamina, also variable in size and shape. Valve marginal lamina with submarginal alveoli followed by large regularly or irregularly arranged areolae. Externally, submarginal alveoli and areolae occluded by cribra. Internally, absence of silicate layers on areolar openings, each areola crossed by thick and inwardly raised circumferential silica trabeculae. Single marginal rimoportula present; externally situated on costa and internally very close to alveolar opening, in oblique position. Marginal fultuportulae positioned on costae and arranged in regular ring, with round and simple external openings at valve-mantle junction. Internally, marginal fultoportulae open through short central tube, laterally surrounded by two satellite pores. Valve face fultoportulae absent. Valvocopula closed, perforated by small pores.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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