A freshwater survey of over thirty-five river catchments throughout mainland New Caledonia ("La Grand Terre ") and a number of caves on Lifou, the Loyalty Islands, yielded four new records of Palaemonidae for the region, viz., Macrobrachium grandimanus (Randall, 1839), M. latimanus (von Martens, 1868), M. microps Holthuis, 1978, and Palaemon concinnus Dana, 1852, which are reported here. Six species had previously been recorded: M. aemulum (Nobili, 1906), M. australe (Guérin-Méneville, 1838), M. caledonicum (J. Roux, 1926), M. equidens (Dana, 1852), M. lar (Fabricius, 1798) and Palaemon debilis Dana, 1852, bringing the total fauna to ten species. A key is provided to the freshwater Palaemonidae of New Caledonia.
