The larval development of the pinnotherid crab Sakaina yokoyai (Glassell, 1933) (Decapoda, Brachyura) inhabiting the Russian waters of the Sea of Japan is described and illustrated for the first time, both from larvae reared in the laboratory and found in the plankton. Like in the closely related S. japonica, the development of S. yokoyai includes three zoeae and one megalopa. A comparative analysis revealed that the larvae of the two Sakaina species are very similar. The zoeal stages of the two congeneric species differ slightly in the setal formulae of antennule, maxillule, and maxilla; the megalopal stages are distinguished by the setal formulae of antennule, maxillule, maxilla, and maxillipeds I-III. The main difference between the zoeal stages of S. yokoyai and S. japonica is the presence of minute lateral spines on the telson in S. yokoyai, which are absent in S. japonica. Le développement larvaire du crabe pinnothéridé Sakaina yokoyai (Glassell, 1933) (Decapoda, Brachyura) habitant les eaux russes de la mer du Japon est décrit et illustré pour la première fois à partir de larves élevées en laboratoire et trouvées dans le plancton. Comme chez l'espèce proche S. japonica, le développement de S. yokoyai comporte trois zoés et une mégalope. Une analyse comparative montre que les larves des deux espèces de Sakaina sont très semblables. Les stades zoés des deux espèces congénères diffèrent légèrement dans la formule du nombre de soies des antennules, maxillules et maxillipèdes I-III. La différence principale entre les stades zoés de S. yokoyai et S. japonica est la présence de minuscules épines latérales sur le telson de S. yokoyai, qui sont absentes chez S. japonica.
