Trichopeltis muratovi sp. n. is described from forest litter in Laos. It differs from the seven known congeners primarily by certain gonopodal details. Trichopeltis cavernicola Golovatch 2016, the only presumed troglobiont among Asian Cryptodesmidae and occurring in a cave in central Laos, is recorded from another cave in the same region. Circulocryptus faillei Golovatch 2016, described from forest litter in a nature reserve in southern Vietnam, is recorded from additional three localities in both southern and central Vietnam. All three species are abundantly illustrated, and variation in both poorly-known ones is presented.
