Two new species of the millipede genus Hypocambala Silvestri, 1895 from China and Vietnam (Diplopoda: Spirostreptida: Cambalopsidae)

摘要

Two new species of the genus Hypocambala are described: H polytricha sp.n., from a cave in Guangxi Province, China, and H. oligotricha sp.n., from a forest in north-central Vietnam. Both of the new species are especially similar to H. vietnamica (Mauries, 1977), from a cave in Ke Bang karst, north-central Vietnam, due to the presence of crests/carinae on the collum and following metazona. A key is proposed to separate these three species.
