Nyssodesmus python individuals can grow quite large for polydesmids with some individuals reaching lengths of up to 10 cm (4 inches).

Genus: Eutrichodesmus

Eutrichodesmus is a reasonably sized genus ( ~30 spp.) of Haplodesmid millipedes which occur throughout parts of Asia. Like other members of the family Haplodesmidae, members of Eutrichodesmus are noted for having elaborate growths on their tergites (the dorsal portion of their exoskeletons). E. aster shown above shows this trait exceptionally.
