The millipede tribe Sundaninini in Vietnam (Diplopoda: Polydesmida: Paradoxosomatidae)

Pseudosundanina gen.nov. is created to accommodate the species Sundanina falcata Attems, 1937 new combination, which is redescribed from near–typotypic material. In addition, two new species of Sundanina are described: S. medialis sp.nov. from northern and S. cochinchina sp.nov. from southern Vietnam. A key is compiled to all four Sundaninini species currently known from Vietnam.
