Barbara Calcinai, Giorgio Bavestrello, and Carlo Cerrano (2005) Six excavating sponge species from the Indo-Pacific area (North Sulawesi, Indonesia, and the Philippines) are described here. Four of these species recorded in Indonesia are new (Cliona albimarginata, Cliona favus, Cliona liangae, and Cliona utricularis); for Cliona dichotoma, collected in Indonesia and the Philippines, this is the 2nd record which enlarges its geographic distribution and allowed us to describe its skeletal arrangement. A redescription of the skeletal arrangement and spicule features of Cliona mucronata is given.

Key words: Excavating sponges, Coral reefs, Porifera, Indonesia, Philippines.
