A new marine epipsammic diatom species, Cymbellonitzschia biseriata C.H. Li, H.H. Liu, Y.H. Gao & C.P. Chen sp. nov. from Fujian Province, China, is described, and is the first record of this genus in China. The morphological observations and species description are based on scanning electron microscopy and light microscopy. The main characteristics of C. biseriata are as follows: valves are semi-lanceolate; striae are biseriate or change from uniseriate to biseriate; canal raphe is located and discontinuous on the ventral side; distal raphe ends are curved and extended to the dorsal side of the valve, forming raised helictoglossae; areolae are occluded by domed hymenes; girdle consists of 4–7 perforated bands. The new species is only known at present from its type locality, Weitou Bay, Quanzhou City, Fujian Province, China. [ABSTRACT FROM AUTHOR]
