Larval Development of Pavapilumnus trispinosus Sakai, 1965 (Crustacea, Brachvura,Xanthidae) Reared in the Laboratory

The larval development of Parupilumnus trispinosus Sakai, 1965 completed in the laboratory consisted of four zoeal stages and one megalopal stage. Completion of the lanral development required at least 18 days at 20-25"C. The morphology of the lanrae of each stage is described in detail, and comparisons are made with larvae of other 11 species of the subfamily Pilumninae. Although, the zoeae of the subfamily Pilumninae show almost consistent characteristics of the mouthpart appendages, in the characteristics of the carapace spines and the abdominal lateral knobs they can be divided into five groups: (1) the genera Heteropanope and Heteropilumnus, (2) the genera Actumnus and Pilumnus, (3) Pilumnopeus makiona and P sewutifrons, (4) Porupilumnus trispinosus, and (5) Pilumnopeus eucratoides and. p indic${\alpha}$.
