The fishes of Danau Sentarum National Park and the Kapuas Lakes Area, Kalimantan Barat, Indonesia

Two hundred and twelve fish species are recorded from the Kapuas Lakes Area (western Borneo). One hundred and forty six species are definitively recorded from within Danau Sentarum National Park (DSNP) boundaries; 43 (29 %) of them have been recorded for the first time during the present survey. Eleven species new to science have been discovered and nine additional species are either new or require further study before their identity can be cleared. Taxonomy of Chitala, Scleropages and Parachela are briefly discussed. The published data do not justify recognising more than one Southeast Asian species of Scleropages. Macrognathus tapirus is proposed as a new replacement name for Mastacembelus paucispinis Fowler, 1939. A neotype is designated for Ophidium aculeatum Bloch. A large number of fish species migrate upriver to headwaters or downriver to the Kapuas main river at some time of the year; in addition there are lateral movements between the rivers and lakes and the flooded forest during the wet season.
