Only two description of larval stage of shripms belonging to Gennadas genus are reported to this time, both of these to Atlantic oceans. During a survey off coast from Caldera, northern Chile, to Easter Island, three morphotypes of mysis stage of shrimp's belonging to Gennadas genus were collected, none of these showed some resemblance with the descriptions in the literature. The results of the descriptions of these samples and his comparation with previously knowed species are showed here.
