ENGLISH ABSTRACT: The five zoea larval stages of the estuarine crab Sesarma eulimene de Man 1897 (Braehyura, Grapsidae) are described in detail from specimens reared in the laboratory. The morphology of larval Grapsidae is briefly discussed and an updated summary of larval diagnostic characters in the genus Sesarma is given as an aid to identifying specimens in plankton samples from South African waters. *********** AFRIKAANSE OPSOMMING: Die vyf so ea larwale stadia van die strandmeerkrap Sesarma aulimene de Man 1897 (Brachyura, Grapsidae) word in besonderhede beskryf aan die hand van voorbeelde wat in die laboratorium grootgemaak is. Die morlologie van die Grapsidae-Iarwe word kortliks beskryf en 'n bygewerkte samevatting van diagnostiese larfeienskappe by die genus Sesarma word gegee om die identifisering van eksemplare in plankton monsters uit Suid-Afrikaanse waters te vergemakJik.
