Nomenclatural notes
"The genus is named in honour of our colleague and dear friend Dr. Michel Poulin (Canadian Museum of Nature, Ottawa, Canada) in recognition of his important research on marine diatoms." - (8 Nov 2015) - M.D. Guiry

Description: Frustules wedge-shaped to rectangular in girdle view. One valve typically concave while other straight. Girdle composed of a large number (>10) of open, perforated bands of different width with occasionally two irregular rows of poroids. Valvocopula bearing a septum at the headpole and the second copula with a septum at the footpole. Valves heteropolar with a broadly rounded headpole and a more acutely rounded footpole. Pseudosepta absent. Apical pore field absent but several more closely-spaced areolae surrounding the distal raphe endings. Raphe straight to very weakly curving. Raphe branch in the headpole shorter than in the footpole. Proximal raphe endings straight to weakly unilaterally deflected. External distal raphe fissures elongated, deflected, located in a shallow groove, covered by a large silica flap extending from both valve apices. Internal proximal raphe endings covered by a silica flap and distal raphe endings straight, terminating on weakly developed helictoglossae. Striae uniseriate, composed of two elongated areolae, clearly separated by the valve face/mantle junction. Areolae occluded in the areolar canal by hymenes.

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

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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