Uca (Minuca) burgersi Holthuis, 1967 was studied in the laboratory under the morphological and systematical stand points. One experiment was carried out involving 100 larvae, derived from one ovigerous female collected in the north coast of the State of São Paulo, Brazil. The experiment were carried out in a climatically controlled room at 25±1ºC and steady saltness of 34‰ The larvae were maintened individually and food consisted of rotifers (Brachionus plicatillis) in the first stage and Artemia sp. in the last stages. Uca (Minuca) burgersi have five or six zoeal stages and a megalopa one. All larval stages were drawn and described in detail. Tables where the morphological characteristic of each stage of the studied specie was described are also included. They were compared with the other species found in the bibliography passible of being analyzed. The comparative studies of the larval forms of each species of Uca showed that they presented a great similarity of characteristics whose specific identifications were only possible with the aid of several structures analyzed together. In the other hand, the differences among the genera of Ocypodinae occurring in Brazil are more conclusive, and can be obtained by the analyses of a few characteristics.
