Larval development of Crangon uritai (Decapoda: Crangonidae) reared in the laboratory

The complete larval development of Crangon uritai Hayashi and Kim is described from laboratory-reared material. This species has five zoeal stages and one postlarva. Detailed morphological descriptions and illustrations of each stage are provided. The larvae of C. uritai present two remarkable differences compared with those of other congeneric species, C. affinis and C. hakodatei: the number of zoeal stages, and in possessing one submarginal seta of antennal scale in zoeal stages. One outstanding simple seta on the rostrum is the only remarkable difference in the postlarval stage.
