M. Williams 2021	<div><p>Bacillaria sinensis Bing Liu &amp; D.M. Williams sp. nov. (Figs 1–29)</p> <p>LM: Valves linear-lanceolate, often with slightly swollen central margins (e.g. Figs 1–9), tapering to cuneate or rostrate apices (Figs 1–11). Valve dimensions (n = 40): 52–84 μm long, 4.6–5.6 μm wide. Fibulae distinct, situated approximately along valve midline, unevenly spaced, 7–12 in 10 μm. Striae indistinct, parallel throughout valve, 27–29 in 10 μm. Fault sites on valve broader side difficult to discern using LM.</p> <p>SEM: Colony and frustule view: Cell to cell attachment forms colony (Figs 12, 13). Frustule composed of (probably) five open girdle bands (Figs 14–17, labeled B1 to B5), four associated with the epivalve, only one is seen with the hypovalve (Figs 16, 17). Pars exterior deeper than pars interior, stepped, two rows of poroids located in pars exterior along midline, except near each apex becoming one row (Figs 15, 16, arrow, 17). Poroids of valvocopula covered externally by hymenes (Figs 15–17).</p> <p>Valve view: Valve linear-lanceolate, with slightly swollen central margins (Figs 18, 24). Raphe nearly central, continuous from pole to pole, distal raphe endings T-shaped (‘tongue-in-groove’ structure); two raphe flanges present on each side of raphe, asymmetrical due to raphe flange on narrower valve side more developed than that on broader side, terminating before reaching poles (Figs 14–23). Transapical ribs originate with raphe ribs, parallel; striae uniseriate, composed of rounded areolae covered by hymenes externally, continuing onto mantle. Marginal spines absent. On broader side of valve, one transapical rib forming two branches at some sites (Figs 19, 21, 25, 28, 29, arrow, respectively), or two merging into one occasionally (Figs 15, curved arrow; 19, 22, 23, 29, three curved arrows, respectively). Fibulae rib-like, arching into cell (Figs 24–29). Two fibular ribs asymmetrical, i.e. fibular rib on broader side of valve more developed than that on narrower side (Fig. 26, arrows). Internally, raphe straight, continuing from pole to pole where its distal raphe fissure curves into raised helictoglossa (Figs 26, 27).</p> <p>Type:— CHINA. Hunan province: West Dongting Lake, Yang’s Village, a sampling point near the lakeshore, 28° 52’ 29.5” N, 112° 16’ 52” E, 50 m asl., <a href="http://tb.plazi.org/GgServer/search?materialsCitation.longitude=112.28111&amp;materialsCitation.latitude=28.87486" title="Search Plazi for locations around (long 112.28111/lat 28.87486)">Bing Liu</a>, 23 rd April 2017 (holotype BM! 81944, specimen circled on slide, illustrated as Fig. 1; isotype JIU! G202101, specimen circled on slide, illustrated as Fig. 3).</p> <p>Etymology:—Named after China where the species was found (the specific locality is Dongting Lake).</p> <p>Ecology:— Bacillaria sinensis was commonly found in the surface sediment collected in West Dongting Lake. Associated species comprised Entomoneis triundulata Bing Liu &amp; D.M. Williams (in Liu et al. 2018: 242), Ulnaria dongtingensis Bing Liu (in Liu et al. 2019: 127), and some species of Navicula Bory (1822: 128), Nitzschia Hassall (1845: 435), Sellaphora Mereschkowsky (1902:186), Surirella Turpin (1828: 362, 363), Tryblionella Smith (1853: 35), and others. The following environmental parameters were measured in the field. Conductivity was 109.3 ± 0.1 μS∙ cm-1, pH was 8.3 ± 0.2 and water temperature was 23.5 ± 0.3 °C. Since the diatom sample was collected using lens tissue from the mud surface and the water conductivity is above 100 μS∙ cm-1, Bacillaria sinensis can be considered an epipelic alkaliphilous diatom characteristic of moderate electrolyte content in freshwaters.</p> </div>	http://treatment.plazi.org/id/038A9F40FFA9336AF2B5FF5EDD79252A	Public Domain	No known copyright restrictions apply.
