We synthesized the current knowledge of cave-dwelling millipede diversity from Guangxi Zhuang Autonomous Region (Guangxi), South China Karst, China and described six new millipede species from four caves from the Guilin area, northeastern Guangxi. Fifty-two cave-dwelling millipedes are known for the region consisting of 38 troglobionts and 14 troglophiles. Of the troglobionts, 24 are presently considered single-cave endemics. New species described here include Hyleoglomeris rukouqu sp. nov. and Hyleoglomeris xuxiakei sp. nov. (Family Glomeridae), Hylomus yuani sp. nov. (Family Paradoxosomatidae), Eutrichodesmus jianjia sp. nov. (Family Haplodesmidae), Trichopeltis liangfengdong sp. nov. (Family Cryptodesmidae), and Glyphiulus maocun sp. nov. (Family Cambalopsidae). Our work also resulted in range expansions of Pacidesmus trifidus Golovatch &amp; Geoffroy, 2014, Blingulus sinicus Zhang &amp; Li, 1981 and Glyphiulus melanoporus Mauriès &amp; Nguyen Duy-Jacquemin, 1997. As with many hypogean animals in Southeast Asia, intensive human activities threaten the persistence of both cave habitats and species. We provide both assessments on the newly described species’ distributions and recommendations for future research and conservation efforts.
