A new species of Opecarcinus Kropp & Manning, 1987, is described from Indonesia and Malaysia. Opecarcinus cathyae sp. nov. is associated with the scleractinian corals Pavona clavus (Dana, 1846) and P. bipartita Nemenzo, 1980, inhabiting crescent-shaped cavities or tunnels on the coral surface. The new species is the ninth assigned to the genus. It can be separated from congeners by the anterolateral orientation of the cornea, the carapace with shallow transverse depressions, lacking longitudinal depressions, and the smooth dorsal margin of the fifth female pereiopod carpus. The distinctive colour pattern can be used as a diagnostic character in live specimens.
1987年，克罗普和曼宁描述了一种新的奥佩卡蟹属物种，该物种来自印度尼西亚和马来西亚。新物种奥佩卡蟹属凯西娅种（Opecarcinus cathyae sp. nov.）与石珊瑚类的棒形蜂巢珊瑚（Pavona clavus，达纳，1846年）和二分蜂巢珊瑚（P. bipartita，内门佐，1980年）有关，栖息在珊瑚表面的新月形洞穴或隧道中。该新物种是该属的第九个物种。它可以通过角膜的前外侧方向（orientaion）、具有浅横向凹陷且无纵向凹陷的头胸甲以及雌性第五步足腕节光滑的背缘与同属其他物种区分开来。独特的颜色模式可作为活体标本的诊断特征。
