Abstract
The present state of knowledge concerning Portunus larvae is reviewed, and the three zoeal and the megalopa stages of P. rubromarginatus are described and figured. Details of appendage setation are tabulated. This species is unusual amongst known Portunus spp. in having only three zoeal stages and, like other Portunus spp. but in contrast with other Portuninae, it has 4 + 4, or 4 + 1 + 4, setae on the posterior telson border.
