On the Parribacus Lobsters (Crustacea: Decapoda: Scyllaridae) of Taiwan

Abstract

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.本報告報導二種棲息於臺灣沿岸岩礁之岩礁扇蝦。分別爲南極岩礁扇蝦Parribacus antarcticus（Lund , 1793）和日本岩礁扇蝦P. Japoraicus（Holthuis, 1960）。此兩種岩礁扇蝦均具經濟價値。前者主要分佈在本省南部沿岸，而後者則以北部沿岸爲多。本文除比較兩種蝦之外部形態特徵、體色外，同時附上檢索表及彩色圖片以供參考。
