All of three known species of the genus Mathildella Guinot et Richer de Forges, 1981, of the family Goneplacidae, M. serrata (Sakai, 1974) from Japan, Taiwan and the Philippines in the North Pacific, M. maxima Guinot et Richer de Forges, 1981 hitherto known from the Tuamotu Islands, New Caledonia and the Loyalty Islands in the South Pacific, and M. rubra Ng et Ho, 2003 from the Philippines are recorded based on the collections of the National Science Museum, Tokyo (NSMT). The biogeographical distribution of M. maxima is extended northwards to the North Pacific. A new species named M. kyushupalauensis is described from the Kyushu-Palau submarine ridge, southwestern Japan, as a fourth species in the genus. It differs from the known species in the confluent first and second anterolateral teeth of the carapace and the first male pleopod weakly curving and tapering toward the small terminal orifice.
