Zoosphaerium piligerum (de Saussure & Zehntner, 1897)

Wesener, Thomas, 2009, Unexplored richness: discovery of 31 new species of Giant Pill-Millipedes endemic to Madagascar, with a special emphasis on microendemism (Diplopoda, Sphaerotheriida), Zootaxa 2097 (1), pp. 1-134 : 114

The Zoosphaerium piligerum species-group

Members of this group share uniquely-shaped posterior telopods, where the width of the elongated movable finger slightly increases towards the tip. Members of this species-group seem to be restricted to the montane rainforest of the island (Fig. 77). One species was described previously, while two more species can be described here.
