Materials & Methods
Collection methods have been described elsewhere (Strack, 1993, 1998; Yonow, 2001). The synonymy includes references from Indonesia, references omitted from previous publications, and recent reviews. In the ‘Material’ section, specimen refers to a preserved animal lodged in the Netherlands Centre for Biodiversity Naturalis, formerly Rijksmuseum van Natuurlijke Historie Leiden, the Netherlands (RMNH), while individual refers to a photographed animal, possibly measured but not collected or preserved. The notes in quotation marks are translations of the Dutch notes written on the RBE field labels. Both Ambonese “specimens” and “individuals” are listed as ‘Material’, as are additional specimens and individuals from Indonesia while non-Indonesian material is listed separately. Some specimens collected from the Philippines and Australia are included in this work and lodged in RMNH Leiden; however, many phyllidiid specimens are from the Natural History Museum (London), the Muséum National d’Histoire Naturelle (Paris), and the Western Australian Museum (Perth) and were examined. The phyllidiid material from Papua New Guinea was examined, sent to Marta Domínguez (Domínguez et al., 2007), and is lodged in the Royal Belgian Institute of Natural Sciences (Brussels).
All radular preparations and colour slides for specimens and individuals included in this paper (as well as those in Yonow, 2001) are deposited in RMNH, Leiden.
