Zoosphaerium Pocock, 1895

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 : 14

Genus Zoosphaerium Pocock, 1895

Type species: Sphaerotherium neptunus Butler, 1872 .

Synonyms: Heligmasoma Chamberlin, 1921 , Globotherium Brolemann, 1922 .

See Wesener & Wägele (2008) for an extensive revision of the genus. Zoosphaerium was divided into speciesgroups, but it remains unclear if those species-groups represent monophyletic units which might deserve generic status. One new species-group, based on Z. blandum ( de Saussure & Zehntner, 1902) is introduced here. Only two of the new species could not be assigned to a species-group.
