Digital elevation map of Ethiopia (generated by using the geographic information system ArcGIS 10.0; elevation in m a.s.l) indicating the currently known distribution of Trioceros wolfgangboehmei sp. nov. east of the Ethiopian Rift in the northern Bale Mountains (red stars; left star: Dinsho, right star: Goba). Black star: Addis Abeba. Grey dots show records of T. affinis based on distributional data after Largen and Spawls (2010) and Ceccarelli et al. (2014). The status of these different Ethiopian populations of T. affinis will be investigated in more detail in further ongoing studies.
