We found two species of galumnid mites from Babeldaob Island of the Palau Republic, which is an island located in the western Pacific Ocean. In the present work, we describe Trichogalumna ekaterinae sp. nov., which is clearly different from other known species of Trichogalumna in the specific structure of sensillus, reduced number of notogastral porose areas, and smaller body size. A supplementary description of another species, Galumna flabellifera, which is recorded for the first time in Palau, is given. Furthermore, we discuss aspects of the distribution, diversity and habitat ecology of species belonging to these genera in the Oriental region.
