Dhanus doveri Bristowe, 1952 is newly synonymized with D. sumatranus, and the type locality of D. sumatranus is confirmed as the Dark Cave, in the Batu Cave system, near Kuala Lumpur. Shravana is confirmed as a senior synonym of Nhatrangia Redikorzev, 1938 and includes 13 species: S. laminata (With, 1906) and S. schwendingeri sp. nov., from Thailand, S. charas sp. nov. and S. withi sp. nov. from Malaysia, S. dawydoffi (Redikorzev, 1938), comb. nov.
