P Jenkins, R Portela-Miguez, and L Tomsett (BMNH) provided access to collections at the Natural History Museum (London). C Mateke (Curator of Mammals, National Museum of Zambia, Livingstone) provided photographs of the field data of all Zambian-based specimens of Hylomyscus anselli , where the majority of specimens from this taxon are housed. Figs. 13 View Fig is courtesy of R Kistinger. Fig. 9d View Fig are based on photos of palate and feet taken by M Lövy and L Pleštilova respectively, using material collected during fieldwork organized by R Šumbera ( Zambia) and J Krásová ( Angola). J Weinstein, Field Museum, Photography, provided the skull and skin photos of the type specimens ( Figs. 5 View Fig , 6 View Fig , 11 View Fig , 12 View Fig ). We thank the Collaborative Invertebrate Laboratories at the Field Museum, Dr M Thayer for use of imaging equipment (funded by NSF grant EF-0531768/subcontract 144–439), the Grainger Foundation, and S Ware for layered photography of Hylomyscus View in CoL palates and tooth rows. WT Stanley took the photos of the live specimens of H. mpungamachagorum and H. stanleyi . SO Bober (FMNH) prepared Fig 3. Q View Fig Luke updated botanical taxonomy and provided important botanical input for Tanzanian localities. MA Rogers has provided crucial data and assistance throughout. We acknowledge the One Health Office, Center for Disease Con- trol and Prevention (Atlanta, USA) and National Institute of Health’s grant 1R01TW008859-01: Sylvatic Reservoirs of Human Monkey Pox for having funded two trips (2012, 2013) to DR Congo. Fieldwork in Angola was supported by the Grant Agency of the University of South Bohemia no. 018/2017/. For work, permits and funding the senior author extend thanks to the following. Burundi: L Davenport, AJ Fisher, A Nibizi, and P Trenchard, with permit approval from the Institut National pour l’Environment et la Conservacion de la Nature (Mr A Nyokindi & Dr L Ntahuga, Directeurs General). For Uganda: M Grey, S Jennings, PK Austin, R Kityo, K Musana, and E Tibenda with permit approval from the Department of Game (Moses Okua) and the Research and Monitoring Section of the Uganda Wildlife Authority. For work in the Democratic Republic of Congo: J Hart and T Hart (TL2 and Epulu), with permit approval from the Institut Nacional pour la Conservacion de la Nature; the scientific team at Lwiro (Centre de Recherché des Sciences Naturelles, Dr A Bash- wira, Scientific Director), including J Mwanga, B Ndara Ruszi- ga, R Kizungu, P Kaleme and R Nishuli. For work in Rwanda: T Mudakikwa (MINIRENA), Minister of Environment; N Ntare, Michel Masozera, Nerissa Chao (all of Wildlife Conservation Society), Rwanda Development Board and National University of Rwanda. For work in Kenya: B Agwanda and S Musila with permits and logistical support from Kenya Forest Service, Kenya Wildlife Service, and the National Museums of Kenya. For financial support, we acknowledge the Barbara Brown Fund, the Ellen Thorne Smith Fund, the Marshall Field III Fund of The Field Museum, the John D and Catherine T MacArthur Foundation, the World Wide Fund for Nature (WWF-Itombwe) and the Wildlife Conservation Society (WCS-Rwanda, DR Congo). F Dowsett-Lemaire, R Dowsett, J Bates and T Butynski provided helpful input on biogeography of birds in Malawi and primates in northern Kenya. Comments from Ryan Norris and one anonymous reviewer are gratefully acknowledged. This project be- gan some 2½ years ago when one of us (RH) noticed that the identification of a specimen from WT Stanley’s collection from the DR Congo did not look like ‘ Dendromus View in CoL ’ as it had been catalogued.
