The complete larval development of Scopimera bitympana Shen was described and illustrated from the larvae reared in the laboratory. S. bitympana had five, or occasionally six, zoeal and one megalopal stages. At 25deg C, the megalopa and the first crab instar were attained in 24 and 38 days (31 and 48 days in six zoeal series) after hatching respectively. S. bitympana zoeae can be distinguished from other described zoeae in the genus by the toothed carapace spines and the telson with a dorsal and two ventral spines. Megalopa of this species can be distinguished from other Scopimera species by the feature of carapace. Other minor morphological features of S. bitympana larvae are compared to the previous descriptions of larvae of the genus and the morphological differences are briefly discussed
