Nupela Vyverman & Compère, 1991
Holotype species: Nupela giluwensis Vyverman & Compère
Original publication and holotype designation: Vijverman, W. & Compère, P. (1991). Nupela giluwensis gen. & spec. nov. A new genus of naviculoid diatoms. Diatom Research 6(1): 175-179.
Taxonomic status: currently recognized as a distinct genus.
Description: Cells solitary. Frustules rectangular in broad girdle view. Valves narrowly elliptical with strongly capitate ends, slightly curved transapically. Axial area linear-lanceolate; central area rectangular, almost reaching valve margins. Under LM 2-4 narrow, slightly undulate longitudinal bands along valve face visible on valve face; transapical striae not visible. Under SEM each stria composed of 2-4 transapically elongate areolae; areolae covered by an inner, centrally perforated hymen. Raphe fissures slightly undulate; raphe endings inconspicuous, terminal fissures sharply curved into one side of valve, proximal endings T-shaped located in a moderately inflated central nodule. Transapically elongate areolae present on mantle.

Comments: Nuplea resembles Brachysira in arrangement of structure of striae on the valve face and mantle, but lacks the longitudinal ribs on either side of the raphe of the latter. Nuplea and Diadesmis have similar proximal raphe endings but different terminal raphe endings. Nuplea was described from freshwater tarns, Papua New Guinea.
Numbers of names and species: There are 86 species names in the database at present, as well as 2 infraspecific names. Of the species names, 85 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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
