According to our morphology and molecular-based results, we were able to identify six species of Phyllidiella : P. pustulosa ( Cuvier, 1804) , P. nigra ( van Hasselt, 1824) , P. zeylanica auctt. (not the original description by Kelaart, 1858, but used by authors in error, see below), P. rudmani Brunckhorst, 1993 , P. albonigra ( Quoy & Gaimard, 1832) , and P. hageni Fahrner & Beck, 2000 , and at least ten clades or subclades that could not be assigned to a named species (Figs. 9, 10, 11, 12). One unexpected result in our tree was the position of the single specimen of an unidentified Ceratophyllidia species from the Philippine Islands ( Hallas et al., 2017). It is placed within Phyllidiella (bootstrap value 79), which would render the genus Phyllidiella paraphyletic if the specimen was correctly identified to genus ( Figs. 13 View Fig , 14 View Fig , 15 View Fig , S 1 View Fig ). The preserved animal has pigment spots on the fleshy papillae consistent with being identifiable with Ceratophyllidia sp. 4 in Gosliner et al. (2015; T.M. Gosliner pers. comm.). All clades of Phyllidiella , including the un-named clades, were supported by high bootstrap values. A few species relationships are supported with highest bootstrap values, e.g., the sister-taxa relationship of P. pustulosa / P. nigra (100) (not supported by the CO1 data set), P. sp. c/ P. albonigra (99), and P. hageni as sister of P. sp. d/ P. sp. complex e (100).
