Tibetiella pulchra Y. L. Li, D. M. Williams et Metzeltin is described from River Nujiang. Its main features are heteropolar valves, which are linear with capitate ends; narrow sternum, expanding at its center; 2–5 rimoportulae at each apex; uniseriate striae; two short projections arising on the surface above each apical pore plate; and an ocellulimbus, extending from the edge of the valve margin to the edge of the valve surface. Of these characters, it is defined by the 2–5 rimoportulae at each apex. T. pulchra was common to abundant on rocks in the samples examined herein.
