The liverwort Ceratolejeunea bardatii sp. nov. (Lejeuneaceae) is described and illustrated from submontane, mesophilous valley forest of New Caledonia. The new species stands out by 1) leaf lobes with a 2-cells wide vitta of dark brown ocelli and some additional adjacent ocelli; 2) upper leaf margins with Allorgella-type denticulations; 3) utricles absent; and 4) perianths short obovoid and with 4 flat or twisted horns. The new species constitutes the first record of the genus Ceratolejeunea for New Caledonia.
