HH Liu, Z Wang, YH Gao & CP Chen, is described as a new species in samples collected from sand grains at Dajing Beach, Ningde City, Fujian Province, China. Morphological details of the new species with respect to valve shape, size and valve ultrastructure are presented based on light microscopy (LM) and scanning electron microscopy (SEM). The main features of under a light microscope are elongated elliptic valves with rounded apices, two internal costae on the valve and rectangular in girdle views. SEM observation showed that externally, the frustules are comprised of two valves with a relatively deep mantle and a transition between the valve faces. Small, flabelliform spines are present along the valve margin. Internally, the valves are divided into three sectors by robust costae, which penetrate the whole valve lumen and are thickest at the mantle interior and thinner toward the center. The sternum is narrow and linear, visible only in the valve apex, set off by costae. The striae are comprised of small, round areolae and they are parallel in the middle to slightly radiate at the apices. The new species is compared with other species in the genus .
HH Liu、Z Wang、YH Gao和CP Chen，在中国福建省宁德市大京海滩的沙粒样本中被描述为一个新物种。基于光学显微镜（LM）和扫描电子显微镜（SEM），呈现了该新物种关于瓣膜形状、大小和瓣膜超微结构的形态学细节。在光学显微镜下，其主要特征为瓣膜呈拉长的椭圆形，顶端圆润，瓣膜上有两条内部肋条，在带面观呈矩形。扫描电子显微镜观察显示，从外部看，硅藻壳由两个瓣膜组成，有相对较深的套膜以及瓣膜面之间的过渡区域。瓣膜边缘有小的扇形刺。在内部，瓣膜被粗壮的肋条分成三个部分，这些肋条贯穿整个瓣膜腔，在套膜内部最厚，向中心逐渐变薄。胸骨狭窄且呈线状，仅在瓣膜顶端可见，由肋条分隔。条纹由小的圆形网孔组成，在中部平行，在顶端略微放射状。将该新物种与该属的其他物种进行了比较。
