023287DDA65CFF97FF4D7FE3FD7BF987.taxon	description	SEM: External views: Raphe almost straight to slightly undulate with central raphe ends dilated, drop-shaped and slightly inclined to the secondary valve side. The terminal fissures clearly hooked in the same direction. Raphe sternum prominently developed, narrow, raised along the raphe, more obviously towards the center (arrow A in Fig. 11). Areolae slit-like (Figs 12, 13), with one row of apical areolae, arranged horizontally, positioned on the valve apex and mantle (arrow B in Fig. 12). Striae uniseriate, with two obviously shortened striae near the central area (arrows C in Fig. 13) and two occasionally intermittent striae (arrows D in Fig. 13). Internal views: Striae uniseriate, irregularly shortened in central area, composed of round-elliptical, roundrectangular areolae, separated by robust silica ribs. Sternum broad and raised, not interrupted, scarcely expanded in the central pore and inclined to the secondary valve side; lacking central area besides the sternum (black arrows in Figs 14, 16). Raphe continuous, lacking an intermissio. Terminal raphe ends terminate in small and knob-like helictoglossae (Fig. 15).	en	Xiao, Qiao-Zhi, Guo, Ji-Shu, Tang, Zheng-Bin, Kociolek, John Patrick, Li, Yan-Ling (2023): Navicula sinicomeniscus sp. nov.

023287DDA65CFF97FF4D7FE3FD7BF987.taxon	biology_ecology	Ecology: Navicula sinicomeniscus was found in a low altitude freshwater lake with moderately alkaline pH (8.71) and very low concentrations of nutrients (TN 0.14 mg ̛ L- 1, TP 0.02 mg ̛ L- 1). The dominant diatom species discovered in this area include Aulacoseira granulata (Ehrenberg) Simonsen (1979: 58) (1.7 %), Cyclotella rhomboideo-elliptica Skuja (1937: 49) (6.9 %), Cyclotella krammeri Håkansson (1990: 263) (46.4 %), Fragilaria crotonensis Kitton (1869: 110) (7.8 %), Stephanodiscus minutulus (Kützing) Cleve & Möller (1882: 300) (1.1 %), Stephanodiscus hantzschii Grunow (in Cleve & Grunow 1880: 121) (8.6 %), and some unidentified species of Achnanthidium Kützing (1844: 152) (6.7 %) and an Amphora Ehrenberg ex Kützing (Kützing 1844: 107) sp. (4.3 %). These entities comprise more than 83 % of all diatoms enumerated in the samples.	en	Xiao, Qiao-Zhi, Guo, Ji-Shu, Tang, Zheng-Bin, Kociolek, John Patrick, Li, Yan-Ling (2023): Navicula sinicomeniscus sp. nov.
