Original publication and holotype designation: Kerhi, S., Edlund, M.B., Spaulding, S., Solak, C.E., Sabouri, J., Izadi, B. & Peszek, L. (2024). Lutophila gen. nov., a new diatom genus from the hottest place on Earth, Lut Desert, Iran. Phytotaxa 641(2): 99-111, 57 figs.

Description: Valves linear-lanceolate, symmetric on apical and transapical axes, strongly parallel sides with broadly rounded apices. In girdle view, symmetric or slightly asymmetric along pervalvar axis. Valves 8.4–20.5 ?m long and 1.6–2.8 ?m wide. Central area hardly distinguishable from the axial area. Axial area symmetric. Raphe straight externally, terminal raphe ends curved to the same side of the valve and proximal raphe ends straight. Internally raphe slightly curved with proximal raphe ends slightly deflected unilaterally and terminal raphe ends ending in small helictoglossae. Striae parallel, 26–28 in 10 ?m; each stria composed of two macroareolae, one macroareola on the valve face and one on the valve mantle. Each macroareola transapically elongate, macroareolae on valve face apically aligned, macroareolae on valve mantle also apically aligned; internal occlusions of macroareolae foriculate, external occlusions of macroareolae hymenate.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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