Rhipicephalus appendiculatus Neumann, 1901 . Afrotropical: 1) Botswana , 2) Burundi , 3) Central African Republic , 4) Comoros , 5) Democratic Republic of the Congo , 6) Eswatini , 7) Kenya , 8) Lesotho , 9) Malawi , 10) Mauritius , 11) Mozambique , 12) Namibia , 13) Rwanda , 14) South Africa , 15) South Sudan , 16) Tanzania , 17) Uganda , 18) Zambia , 19) Zimbabwe ( Yeoman & Walker 1967 , Walker 1974 , Barré & Morel 1983 , Keirans 1985 b , Matthysse & Colbo 1987, Tandon 1991 , Walker et al. 2000 , De Deken et al. 2007 , Lynen et al. 2007 , ElGhali & Hassan 2012 , Stachurski et al. 2013 , Uilenberg et al. 2013 , Horak et al. 2018 , Ledger et al. 2021 , Mahlobo & Zishiri 2021 , Olivieri et al. 2021 , Shekede et al. 2021 ). All stages of Rhipicephalus appendiculatus are morphologically very similar to those of Rhipicephalus zambeziensis , but Rhipicephalus appendiculatus has also been confused with Rhipicephalus duttoni and Rhipicephalus nitens , as discussed in Walker et al. (2000) , while Horak et al. (2018) stated that Rhipicephalus warburtoni has been confused with atypical Rhipicephalus appendiculatus . Uilenberg et al. (2013) noted that Rhipicephalus appendiculatus has not been found recently in the Central African Republic , but these authors consider it probable that this species remains present in that country, which is here provisionally included within the geographic distribution of this tick. Ghosh et al. (2007) and Farooqi et al. (2017) , among others, recorded Rhipicephalus appendiculatus from Pakistan (Oriental and Palearctic Zoogeographic Regions), but that country is here excluded from the range of this tick. Fakoorziba et al. (2015) allegedly found Rhipicephalus appendiculatus in Iran , a record treated as valid in Nasirian (2022) but that requires confirmation, and Iran is excluded from the range of this tick. Okely et al. (2022) stated that Rhipicephalus appendiculatus was reported in Egypt , while also stating that it is not established there. Ekanem et al. (2011) and Wahedi et al. (2020) listed Rhipicephalus appendiculatus as occurring in Nigeria , but its presence there requires confirmation. Perveen et al. (2021) stated that Rhipicephalus appendiculatus has been recorded from Sudan and the United Arab Emirates , but this statement could not be confirmed using the references provided by these authors. Gargili et al. (2017) included Armenia within the range of Rhipicephalus appendiculatus , again citing a reference that does not support its presence there. Clavijo et al. (2009) reported Rhipicephalus appendiculatus sent from England to Venezuela , but Guglielmone et al. (2014) presumed that the specimens were of African origin.
