(2002), Largen & Spawls (2006) and our own morphol- ogy studies of the two species support Klause witz (1957) who regarded them as two distinct species. The reported distribution of both taxa is unclear because of the inen- tioned taxonomic problems. Despite the works of Klausewttz (1954, 1957), a new re- view of the Acanthocerciis- species complex is needed. The review will be a part of the PhD thesis of the senior author. The diagnoses of the subspecies of A. atricollis by Klause witz (1957) are not adequate. Therefore, the ma- terial is only preliminarily assigned to the subspecies ugandaensis because Kakainega Forest is geographical- ly closer to the area of this subspecies than to minuta, ac- cording to Klausewitz's (1957) map: A. a. minuta inhab- its Ethiopia and eastern Kenya, while A. atricollis ugan- daensis occurs within Uganda and western Fig. 10. .Agama kaimosae fi-om Ngoromosi/ Nandi escarpment.
