Zoosphaerium platylabum   species-group

SPECIES INCLUDED. — Zoosphaerium platylabum (de Saussure & Zehntner, 1897)   .

DISTRIBUTION. — Unclear, since most species are still undescribed.

DIAGNOSIS. — This species group is still monotypic, but numerous undescribed species close to Z. platylabum   were discovered, justifying its establishment. The characters unifying this group are unique in Sphaerotheriida   .

All species have 2 locking carinae on the ventral side of the anal shield. The carinae are located more closely to the laterotergites than towards the anal shield margin ( Fig. 30E View FIG ). The operculum of female vulva is protruding into 2, sharp edged processes. ( Fig. 30F View FIG ). A phylogenetic analysis will be necessary to confirm if the platylabum   -group represents a monophyletic group to be kept separately from the other Malagasy sphaerotheriids.
