Amblyomma eburneum Gerstäcker, 1873 . Afrotropical: 1) Congo , 2) Eritrea , 3) Ethiopia , 4) Kenya , 5) Mozambique , 6) Rwanda , 7) Somalia , 8) Tanzania , 9) Zimbabwe ( Theiler 1962 , Elbl & Anastos 1966 a , Yeoman & Walker 1967, Bergeon & Balis 1974 , Walker 1974 , Kariuki et al. 2019 , Olivieri et al. 2021 ). Matthysse & Colbo (1987) and others stated that adults of Amblyomma eburneum can be confused with those of Amblyomma gemma , and the females of Amblyomma eburneum and Amblyomma lepidum are not readily separable morphologically. Morel (1980) doubted the presence of Amblyomma eburneum in Ethiopia , and this country is provisionally included within the range of this tick. Matthysse & Colbo (1987) asserted that Amblyomma eburneum has not been found in the Democratic Republic of the Congo . There are two records of this tick from that country in Elbl & Anastos (1966a) , although these authors state that they may be “accidental,” while Tandon (1991) listed a record of Amblyomma eburenum from Zambia but believed that this tick is not established there. We have provisionally excluded the Democratic Republic of the Congo and Zambia from the range of this tick. Okely et al. (2022) listed a record from Egypt but stated that this species is not established in that country. Kolonin (2009) stated that his understanding of the geographic distribution of Amblyomma eburneum was based on Voltzit & Keirans (2003) , but there are discordances between these studies. Data concerning Amblyomma eburneum should be considered provisional.
