Chromodoris magnifica (Quoy & Gaimard, 1832), a new nudibranch host for the shrimp Periclimenes imperator Bruce, 1967 (Pontoniinae)

During the NNM/Maluku Expedition 1996, in the framework of the NNM Fauna Malesiana Marine Program, a shrimp belonging to the species Periclimenes imperator Bruce, 1967, was found on a nudibranch while diving at 20 m depth in Seri Bay, on the south coast of Ambon. Periclimens imperator has been recorded throughout the tropical Indo-West Pacific, from East Africa and the Red Sea to Hawaii, from nudibranch and holothurian hosts. The nudibranch was identified as Chromodorus magnifica (Quoy & Gaimard, 1832) (see Rudman, 1982: 216-219, figs. 17A, B, 18, 19). The association with Chromodorus magnifica is recorded here for the first time.
