Currently, only eight species of Monstrobovella are known from Southeast Asia and South America. In this paper, two new and unusual species of Monstrobovella are described from soil samples collected in Southeast Asia. Both species are characterized by the presence of long caudal setae on an elevated part of the dorsal shield. The first species, M. mandalaya sp. nov. from Myanmar, is distinguished by robust and marginally serrate setae on the central area of the dorsal shield. The second species, M. champa sp. nov. from Vietnam, also has very long caudal setae on the dorsal shield, which are twice as long as those of the first species, while the setae on the central area of the dorsal shield are narrow and smooth.
