A new cave‐dwelling millipede of the genus Bollmania Silvestri, 1896 from Yunnan,China, with remarks on the reduction of the second female leg‐pair (Diplopoda: Callipodida: Caspiopetalidae)

Bollmania beroni sp. n., described from a cave in Jianshui County, Yunnan, China is the first true troglo‐ and hygrophilic species in the genus. The new locality extends the range of Bollmania ca 2500?km towards SE, ca 1700?km SW of the only other Chinese record. Notes are given on B. orientalis (Silvestri, ), B. nodifrons Lohmander, and B. oblonga Golovatch, , based on new material from Turkmenistan and Tajikistan, and on two unnamed, probably new species from Afghanistan. An updated key to the eight described species is presented. Original observations and illustrations of second female legs in various callipodid genera are presented, along with a literature review of this character, which has so far received little attention from taxonomists.
