A new sponge species Amphimedon denhartogi spec. nov., belonging to the family Niphatidae of the order Haplosclerida, is described from 3 localities in Indonesia: Tulamben (NE Bali), Siladen Island (NE Sulawesi) and Kambing Island (SW Sulawesi). Amphimedon denhartogi spec. nov. is characterised by its growth form of thinly flabellate branches, the occurrence of star-shaped oscules over one side of the sponge body, and by its small strongyles, and can hardly be confused with another species. All specimens were found in similar habitats, at around 40-45 m of depth on steep sandy slopes.
