A new tubificid oligochaete, Aulodrilus acutus, is described from Padang, West Sumatra, Indonesia. It resembles Aulodrilus pigueti Kowalewski by sharing oar-shaped chaetae, globular atria, and a median male bursa, but is distinguished by having tapering distal ends to the oar-shaped chaetae and by lacking penial chaetae and the associated glands. Aulodrilus pigueti and Teneridrilus sp. are also described. Branchiura sowerbyi and Limnodrilus hoffmeisteri are recorded from Sumatra.
