Didrepanephorus baron sp. n. is described from Dalat Highlands (Viet Nam). It is most similar to D. anthracinus (Ohaus), but differs by the structure of the parameres, coloration and some other minor details. The similarities between the new species and Fruhstorferia javana Kolbe are noted; on this ground, the modern generic classification of the tribe Fruhstorferiini is discussed. Diagnosis of the new species: D. baron sp. n. differs from all other species within the group in the shape of male genitalia. It can be distinguished from all the species except D. anthracinus in combination of the reduced prosternal process, sternites 1-4 abbreviated medially in males, and the male frontal processes pointed and triangular in shape. It further differs from D. anthracinus in coloration (uniformly coal-black from above and below in both sexes of D. anthracinus and mostly red-brown from above in D. baron), less developed punctures on the head and pronotum in males, deeper subbasal concavities on the sides of the pronotum, shape of the male ocular canthus, and in the left paramere forming a long and curved process.
