Abstract: Two new species of Dineutus Macleay, 1825 (Coleoptera: Gyrinidae) are described and illustrated: Dineutus barong sp. nov. from Bali, Indonesia and Dineutus sitesi sp. nov. from Thailand. A checklist to the species of the Dineutus s. str. is provided, as is a key to the species currently recognized in the subgenus together with illustrations of habitus, elytral apices and aedeagi of the species. Dineutus lethicus Guignot, 1957 syn. nov. is removed from Dineutus s. str. and it is synonymized with Dineutus (Protodineutus) indus olivaceus Régimbart, 1882.
