Zocci

Zocci were the species to which Bannakaffalatta belonged. They were small humanoids, with red spiky heads. (DW: Voyage of the Damned)

The Zocci are related to the Vinvocci. (DW: The End of Time)

Behind the Scenes
The word Zocci does not appear onscreen. Russell T Davies, however, has given this as the name of Bannakaffalatta's species. It is later stated in The End of Time by a member of a similar species.
