The genus Nedyopus Attems, 1914 consisting of 22 known species and subspecies is distributed mainly in East Asia (Japan, Taiwan) and expansively occurs in Vietnam (three species). The paper presents taxonomy and diagnosis of three Nedyopus species recorded in Vietnam: N. dawydoffiae (Attems, 1953), N. mahunkai (Korsós & Golovatch, 1989) and N. pictus (Brölemann, 1916). Of those, N. mahunkai has been widely known in northeastern Vietnam, and N. dawydoffiae has been found in southern Vietnam. The species N. pictus has been recorded only in Tam Dao National Park. A key to species is also provided. | The millipede genus Nedyopus Attems, 1914 (Diplopoda: Polydesmida: Paradoxosomatidae) from Vietnam
