Abstract

The zoeal development of four species of Petrolisthes, P. asiaticus, P. hastatus, P. moluccensis, and P. tomentosus, is described and illustrated based on material reared in the laboratory. These species possess two zoeal stages. The zoeae of all four species belong to Group 4 of Osawa (1995), based on the morphological characters of the maxilla, first maxilliped, and telson. The Indo-West Pacific species assigned to this group, except for P. boscii, share a characteristic kind of telson that has a bifid spine at each lateral angle in the first zoea. This feature is also found in zoeae of Neopetrolisthes.
