Abstract
The name Rondostreptus kiellandi is proposed for an undescribed genus and species of Spirostreptidae apparently endemic to the Rondo Plateau in southeastern Tanzania. It appears to have no close relatives among the known spirostreptid fauna of East Africa. The Rondo Plateau is an elevatefi region west of Lindi, in the coastal plain of southeastern Tanzania. With an estimated area of about 500 square miles above 1500 feet, and a maximum elevation of 2900 feet ASL (885 m), this landmass is a physiographic feature of potential biogeographic interest. It is one of the last parts of Tanzania to be investigated in terms of local biota, but one regrettably not neglected by commercial interests engaged in removal of the native forest during the past 150 years.
