Abstract

Seven new species of oribatid mites of the genus Galumna are described from litter and soil materials of Sumatra, Indonesia. A new subgenus, Galumna (Atypicogalumna) subgen. n., is proposed; it differs from all galumnid genera and subgenera by the simultaneous presence of porose areas and sacculi on the notogaster (vs. either porose areas or sacculi present). Galumna (Galumna) calva Stary, 1997 is recorded for the first time in the Oriental region, and G. (G.) sabahna Mahunka, 1995 is recorded for the first time in the Indonesian fauna.
