Amblyomma cohaerens D ö nitz, 1909 . Afrotropical: 1) Angola , 2) Burundi , 3) Democratic Republic of the Congo , 4) Ethiopia , 5) Kenya , 6) Rwanda , 7) South Sudan , 8) Tanzania , 9) Uganda ( Theiler 1962 , Yeoman & Walker 1967 , Pegram et al. 1981 , Keirans 1985 b , Walker & Olwage 1987, Kolonin 2009 , ElGhali & Hassan 2012 , Olivieri et al. 2021 ). Guglielmone et al. (2020) discussed the problems associated with the identification of Amblyomma cohaerens , stressing morphological discrepancies among authors who have redescribed this tick, which has been widely confused with several other species of African Amblyomma . Hoogstraal (1956a) and Matthysse & Colbo (1987) stated that the females of Amblyomma cohaerens and Amblyomma splendidum are morphologically indistinguishable, noting also that this tick has been confused with Amblyomma astrion and Amblyomma hebraeum . Morel (2003) separated Amblyomma astrion , Amblyomma cohaerens and Amblyomma splendidum based on ecological considerations rather than morphological characters. Consequently, collection data concerning Amblyomma cohaerens , Amblyomma astrion and Amblyomma splendidum should be considered provisional. The presence of Amblyomma cohaerens in Angola is based on Keirans (1985b) , who re-identified as Amblyomma cohaerens a male tick collected in that country and previously classified as Amblyomma astrion .
