[The Black Sea fauna has been studied for a long time, whence the adult crabs of this region are rather well known. However, not enough attention has been paid to their larval development. Despite the extensive literature concerning the order Decapoda pertaining to the Black Sea, there is no key for the identification of the brachyuran larvae. This work aims to fill that gap. There are 20 species of crabs in the Black Sea, belonging to 7 families: Cancridae with 1 species: Cancer pagurus L., 1758; Pirimelidae with 2 spp.; Portunidae (6 spp.); Xanthidae (4 spp.); Grapsidae (3 spp.; the presence of Planes minutus (L., 1758) for the Black Sea is not confirmed, therefore this species has not been included in the key); Majidae (3 spp.); and Potamidae (1 sp.). In this compilation, descriptions for the larvae of the families Cancridae and Potamidae are absent, because Potamon potamios (Olivier, 1804) has direct development, and the presence of Cancer pagurus is yet to be confirmed. The author presents no keys for some stages of larvae development, and no description of some stages, for various species: these blanks are due entirely to a lack of material. La faune de la mer Noire a ete etudiee depuis longtemps. Aussi, les crabes adultes de cette region sont-ils assez bien connus. Cependant, il n'a pas ete accorde assez d'attention a leur developpement larvaire. En depit de la litterature extensive consacree aux Decapodes de mer Noire, il n'existe pas de cle d'identification des larves de Brachyoures. Ce travail est destine a combler cette lacune. Il y a en mer Noire 20 especes de crabes appartenant a 7 familles: Cancridae (1 espece: Cancer pagurus L., 1758); Pirimelidae (2 spp.); Portunidae (6 spp.); Xanthidae (4 spp.); Grapsidae (3 spp.; mais la presence de Planes minutus (L., 1758) reste a confirmer et, en consequent, cette espece n'a pas ete inclus dans les cles); Majidae (3 spp.); Potamidae (1 sp.). Dans la presente compilation, il n'y a pas de descriptions pour les familles des Cancridae et des Potamidae, car Potamon potamios (Olivier, 1804) a un developpement direct et la presence de Cancer pagurus reste a confirmer., The Black Sea fauna has been studied for a long time, whence the adult crabs of this region are rather well known.
