Pedicularia vanderlandi spec. nov., a symbiotic snail (Caenogastropoda: Ovulidae) on the hydrocoral Distichopora vervoorti Cairns & Hoeksema, 1998 (Hydrozoa: Stylasteridae), from Bali, Indonesia

A new species of ovulid gastropod is described from Bali as Pedicularia vanderlandi spec. nov. It was predominantly found in shallow water on the stylasterid hydrocoral Distichopora vervoorti Cairns & Hoeksema, 1998. The snails are compared with type specimens of congeneric taxa and with material of Pedicularia pacifica Pease, 1865, which was found in shallow water on an unidentified Stylaster. Various notes on Indo Pacific Pedicularia species are given in an annotated, preliminary check-list. Finally, the host relationships of Pedicularia are discussed in general.
