The short-tailed Aethomys of Angola (Mammalia: Rodentia: Muridae)
1999
Crawford-Cabral, J.
Aethomys thomasi and A.kaiseri vernayi are two rodents originally described from Angola, both of them characterized by the tail length, shorter than the head and body, and by the conformation of the brain case, due to the particular shape of the interparietal bone. A third form of Aethomys with relatively short tails (subequal in length to the head and body) also occurs in Angola, as it is judged from three specimens from Duque de Braganca. Specimens from A. thomasi and A. kaiseri vernayi, borrowed of the Instituto Superior de Ciencias da Educacao, Lubango, Angola, as well as the specimens from Duque de Braganca, borrowed of the Field Museum of Natural History, Chicago, were examined and measured, and their skull measurements compared by principal component analysis; further analyses were done, by including data from the literature and measurements of specimens of A. bocagei. The results were interpreted on taxonomic and zoogeographic grounds
