Three new species of the family Rotundabaloghiidae are discovered and described from Sabah, Malaysia. The unusual Angulobaloghiarutra sp. n. differs from the other known Angulobaloghia Hirschmann, 1979 species in the long anterior process of the female's genital shield. Rotundabaloghia (Circobaloghia) tobiasisp. n. has very long and apically pilose dorsal setae and two pairs of bulbiform setae, which are unique in the subgenus Rotundabaloghia (Circobaloghia) Hirschmann, 1975. The long, serrate and curved setae in the big ventral cavity of Depressorotunda (Depressorotunda) serratasp. n. is a so far unknown character in the subgenus Depressorotunda (Depressorotunda) Kontschán, 2010.
