In addition to the long recorded Parribacus antarcticus (Lund, 1793), one more Parribacus species, P. japonicus Holthuis, 1960, is found in Taiwan. Both species inhabit rocky and coral reefs, but with P. faponicus appeared to be mainly distributed off the northern coast while P. antarcticus mostly in the south. These slipper lobsters are taken incidental to fisheries for spiny lobsters and are highly valued sea-food. A key to their identification and color illustrations of these two Parribacus lobsters are provided.
