The millipede family Diplomaragnidae in Taiwan, with descriptions of nine new species (Diplopoda, Chordeumatida)

Diplomaragnidae are currently represented in Taiwan by twelve species in two genera. Nine species are described here as new to science: Tokyosoma serratum sp. nov., Tokyosoma taroko sp. nov., Tokyosoma fanfan sp. nov., Tokyosoma lobatum sp. nov., Tokyosoma bifurcatum sp. nov., Tokyosoma breviprocessum sp. nov., Tokyosoma distinctum sp. nov., Tokyosoma spinifer sp. nov., and Tokyosoma cornutum sp. nov. Two older species remain dubious as elements of the Taiwanese fauna. Eleven diplomaragnids seem to be endemic to Taiwan. The following new combination is proposed: Diplomaragna australis Shear, 1999 = Tokyosoma australe (Shear, 1999), comb. nov. A key is given to all Diplomaragnidae presently known from Taiwan, and the distributions of Taiwanese Tokyosoma species are mapped and discussed. The distinguishing characters of the genus Tokyosoma, as well as variation in T. australe are discussed.
