Abstract
|
|
|
|
One ovigerous crab of He mig raps us longitarsis (Miers, 1879) was collected in Jeju Island, Korea and their larvae were reared in the laboratory. Five zoeal and one megalopal stages are described and illustrated in detail. Morphology of the zoeas slightly differs from that in the previous record. Within the genus Hemigrapsus, H. longitarsis shows similarity closer to H. sanguineus and H. penicillatus than to H. sinens is based on the zoeal morphology. The zoeas of H. longitarsis can be distinguished from those of the two other species in having a dorsal carapace spine with minute spinules which is naked in H. sanguineus and H. penicillatus, A provisional key is provided to aid the identification of the grapsid zoeas in Korea.
