This paper deals with nine new holothurian species viz. Duasmodactyla turriculacava, Cucumella indonesia, Psolus solidus, Holothuria (Acanthotrapeza) tripilata, Holothuria (Metriatyla) horrida, Allopatides corrugatus, Bathyherpystikes baculosus, Paroriza verrucosa, Laetmogone parvipedata, and three rare species viz. Thyone anomala Oestergren, 1898, Stolus papillatus (Sluiter, 1887), Psolidum rugosum Koehler & Vaney, 1905. These holothurians, collected during the Snellius-II Expedition, come from East Indonesia. Most of them were collected deeper than 100m. For each species, a description, a diagnosis, and a discussion on the relation with the nearest species are given. |
