ABSTRACT. A collection of Diplopoda from a national park in the Gia Lai Province of southern Vietnam contains three noteworthy species of Polydesmida: Platyrhacus similis Golovatch et Nguyen, 2007 (Platyrhacidae), Tylopus tuberculatus Golovatch et Semenyuk, 2018, and Enghoffosoma speculiforme sp.n. (both Paradoxosomatidae). All three species are illustrated with colour pictures, Platyrhacus similis is recorded from the Gia Lai Province for the first time, Tylopus tuberculatus is represented by strict typotypes, while Enghoffosoma speculiforme sp.n. is a sixth species of the genus to be reported from Vietnam, differing from all other 12 congeners primarily by the mirror-shaped postfemoral process of the gonopod.
