            <p>Holotype</p>
            <p>(here designated): slide DJ1805 (AU, Biology Department Herbarium, Xiamen University). Fig. 2E represents holotype.</p>
            <p>Type locality.</p>
            <p>Sand beach in Dajing County, Fujian Province, China, 26°42'34"N, 120°7'17"E, leg. Zhen Wang in May 2018</p>
            <p>Etymology.</p>
            <p> The epithet "  Ambo dajingensis " refers to the site where this specimen was collected. </p>
            <p>Description.</p>
            <p> LM observations (Fig. 2A-I): The cells are connected to each other to form short chains and they live in groups. The girdle is comprised of several plain and open bands. The valves are linear elliptic with two costae that are straight or slightly curved to the outside and protrude deeply into the valve. The valve is 6-10  μm long and 2.4-3  μm wide. </p>
            <p> SEM observations (Figs 3, 4): Through the observation of the samples treated by the critical point drying method, the cells on the girdle band valve are rectangular (Fig. 3A), with a wrapped layer of membrane. Several girdle bands (Fig. 3D) are connected between the epitheca and hypotheca valves. The girdle band has fine vertical lines (Fig. 3D) but no obvious spot pattern. Areolae can be observed at both ends of the valve, and the area of the areolae extends to the sternum, but there are no areolae or other cell structures in the middle of the cell (Fig. 3A, B). There is a circle of spines for cell connection at the edge of the valve (Fig. 3A-D). The single row of slightly radial striae is distributed at both ends of the cell (Fig. 3A). Observation of the samples processed by the acidification method showed striae at both ends of the cells and a narrow sternum in the center of the cells in the area of striae, but the sterna were not obvious. To the two ends of the valve, the striae at both ends of the valve extended from the valve in a single row, and the number of striae was 50-60 in 10  μm . The areolae on the valve are round, small, simple, and have no complex structure, such as a cribrum. A small circular area free of areolae is distinctly set off from the striae, and can be observed at the apical part of mantle area with several elongate areolae following the general pattern of the mantle (Fig. 3E, F). On the edge of the valve, there is a row of densely distributed small spines. </p>
            <p>Internally, the valves are divided into three sectors by robust costae (Fig. 4A, C). The interior of the valve face is flat, the transition from the valve face to the mantle is abrupt (Fig. 4A). The transapical striae are composed internally of small, round areolae, and they are parallel in the middle to slightly radiate at the apices. The sternum is narrow and linear, set off by costae (Fig. 4A).</p>
            <p>Distribution.</p>
            <p>Marine, coastal. Collected from Dajing beach on sandy shores. Changchun Town, Xiapu, Ningde City, Fujian Province.</p>
            <p>Molecular phylogeny</p>
            <p> Phylogenetic analysis of molecular data was conducted using a rbc L-gene dataset. The tree inferred from Maximum-Likelihood Phylogenies (MLP) analysis (Fig. 5) of the concatenated rbc L-gene dataset recovered the genus  Ambo (represented by  A. tenuissimus ,  Ambo dajingensis and  A. gallaeciae ) within the araphid diatoms, sister (bootstrap support [bs] = 100%) to a clade with  Diatoma moniliforma ,  Diatoma tenue , and  Asterionella formosa .  Ambo dajingensis and  A. gallaeciae were sister to a clade, but with low support. The phylogenetic relationships of the new species were sustained by genetic distance estimation. The sequences generated in the study were deposited in GenBank under access number OL457301.1. </p>
