First record of the order Polyzoniida from the Indian subcontinent with an integrative description of a new genus (Diplopoda, Colobognatha, Siphonotidae).

Considering the large area of the Indian subcontinent, its known millipede diversity is sparse with only ca. 270 described species in 90 genera, 25 families and 11 orders. So far, not a single polyzoniidan millipede has been described from India.

The millipedes collected by the Museum "La Specola" on Madagascar 1989/1991, with the description of three new species of giant pill-millipedes (Diplopoda, Sphaerotheriida, Arthrosphaeridae).

A large collection of millipedes (Diplopoda) from Madagascar, belonging to the Museum "La Specola" in Florence, Italy were investigated. The collection includes three new species of the giant pill-millipede genus Pocock, 1895 which are described here as Wesener, , Anilkumar & Wesener, , and Anilkumar & Wesener, , all belonging to the species group. The latter two are currently only known from a single site.
