Review of the millipede genus Eutrichodesmus Silvestri, 1910, in China, with descriptions of new cavernicolous species (Diplopoda, Polydesmida, Haplodesmidae).

The Eutrichodesmus fauna of mainland China, by far the largest genus in the Indo-Australian family Haplodesmidae, is reviewed and shown to encompass 23 species (of a total of 45), all keyed. The following nine new species, all presumed troglobites, are described: Eutrichodesmustriangularis sp. n., from Sichuan, Eutrichodesmuslipsae sp. n., from Guangxi, Eutrichodesmustenuis sp. n., Eutrichodesmustrontelji sp. n., Eutrichodesmuslatellai sp. n., Eutrichodesmusobliteratus sp. n. and Eutrichodesmustroglobius sp. n., all from Guizhou, Eutrichodesmussketi sp. n., from Hunan, and Eutrichodesmusapicalis sp. n., from Hubei.
