Zoeal, megalopal and first crab stages of Pagurus nigrofascia are described and illustrated from laboratory reared specimens. Larvae were reared at temperatures 6°C, 12°C, 18°C, and 25°C. Survival rates of larvae were considerably higher at 12°C and 18°C, but were low at 6°C and 25°C. Larvae and postlarvae of P. nigrofascia can be distinguished from seven morphologically similar species based on adult or larval morphological features. Zoeal stages of this species are distinguished by, for example, setal formulae of maxillule, maxilla and maxilliped 1. The megalopal stage can be identified by the telsonal process, the number of articles of the flagellum of antenna and setal formula on the scaphognathite of the maxilla. Morphological features of P. nigrofascia larvae are similar to those of P. ochotensis, P. kennerlyi and P. pectinatus.
