Abstract

The two zoeal and megalopal stages of Porcellana cancrisocialis are described and illustrated from laboratory-reared larvae. At an average temperature of 25°C, Zoea I of P. cancrisocialis lasted seven days before moulting to Zoea II which, in turn, lasted eight days to reach the megalopa. Larval features of P. cancrisocialis are compared with those of other species of Porcellana. Porcellana cancrisocialis exhibits similar but distinguishable features from those observed in Porcellana sigsbeiana and Porcellana platycheles. This species resembles P. sigsbeiana more than P. platycheles in the setation and aesthetasc pattern of Zoea I and II, but the relationships of these three species are not clear.
