Abstract
The Java Sea region has a high diversity of marine organisms of interest to scientists and tourists alike. Neglected among this diversity are intertidal bryozoans, relatively few of which have been reported from this area. Here we describe six species, one of which is new to science. These were collected from three shallow-water localities—Karimunjawa Marine National Park, Awur Bay and Panjang Island—in the south-central part of the sea. The five known species belong to the families Candidae, Poricellariidae, Onychocellidae, Lepraliellidae, and Phidoloporidae. The new species, Pleurocodonellina jeparaensis n. sp. (Smittinidae), is found at Awur Bay, attached to a bivalve shell fragment. Biogeographically, the suite of species is predominantly tropical Indo-West Pacific in distribution, representing a small fraction of the additional hundreds of species that are anticipated for the Java Sea region.
