LARVAL DEVELOPMENT IN PHIMOCHIRUS-ROSEUS (BENEDICT) (DECAPODA, ANOMURA, PAGURIDAE) REARED IN THE LABORATORY

The zoeal and megalopal stages of Phimochirus roseus (Benedict, 1892) are described and illustrated from material reared under laboratory co nditions. Although the vast majority of zoeae of this species pass thr ough only four larval stages before the moult to megalopa, an occasion al fifth stage has been observed. Phimochirus roseus differs in a numb er of morphological attributes from the only other species of Phimochi rus whose larvae have been described. However, their shared features a re sufficiently characteristic to confirm the distinctiveness of the g enus and its general developmental homogeneity.
