Zoosphaerium lambertoni Jeekel 1999: 13 (lists species name). — Enghoff 2003: 20 (lists species name). REMARKS This species seems to be closely related to Zoosphaerium arborealis . The type was stored by Brolemann (1922) at the Académie malgache, an institution that does no longer exist. Some of the material of the former Académie malgache is now stored in the zoological collection at Tsimbazawa, Antananarivo , Madagascar . It is unclear, if the holotype and only known individual of Z. lambertoni still exists in this collection. Even if it is lost, Zoosphaerium lambertoni (Broelemann, 1922) is not listed as a nomen dubium , because we have high-quality drawings provided by Brolemann and a locality (“environs de Tanarive”; Fig. 13 ), which will perhaps allow the collection and determination of a neotype .
