Three new species of Lentipes (L. argenteus, L. ikeae and L. mekonggaensis), freshwater gobies, are described from streams of Sumatra, Java, Bali and Sulawesi (Indonesia). They differ from other species of the genus by a combination of characters including an urogenital papilla lacking lateral lobes and retractable into a sheath-like groove, the number of pectoral fin rays, the number of scales, tricuspid teeth in the upper jaw, and a specific body colour in males.
