ON TWO NEW SPECIES OF CATOPTRUS A. MILNE-EDWARDS, 1870 (DECAPODA, BRACHYURA, PORTUNIDAE) FROM CHINA

摘要

Two new species of Catoptrus A. Milne-Edwards, 1870, Catoptrus quinquedentatus sp. nov. and Catoptrus undulatipes sp. nov. (Portunidae, Carupinae), are described from the South China Sea, and their affinities with allied taxa are discussed. The genusCatoptrus A. Milne-Edwards, 1870 is currently represented by three known species, viz., C. nitidus A. Milne-Edwards, 1870, C. rathbunae Serene, 1966, and C. inaequalis Rathbun, 1906 (cf. Stephenson, 1972). As a part of our ongoing studies on the portunidfauna of China, we recently examined a lot of the specimens collected from the South China Sea. We found two undecribed species of Catoptrus. These two new species, Catoptrus quinquedentatus sp. nov. and Catoptrus undulatipes sp. nov. are herein described from the South China Sea.
