Guglielmone, Alberto A., Nava, Santiago & Robbins, Richard G., 2023, Geographic distribution of the hard ticks (Acari: Ixodida: Ixodidae) of the world by countries and territories, Zootaxa 5251 (1), pp. 1-274 : 54

75. Amblyomma marmoreum Koch, 1844a .

Afrotropical: 1) Botswana, 2) Eswatini, 3) Lesotho, 4) Mozambique, 5) Namibia, 6) South Africa, 7) Zambia, 8) Zimbabwe ( Colbo 1973, Tandon 1991, Walker & Olwage 1987, Burridge 2011, Horak et al. 2018).

The geographic distribution of Amblyomma marmoreum is chiefly based on Walker & Olwage (1987) and Horak et al. (2018), and many records published prior to these studies are not included in this analysis.

Kwak et al. (2014) identified several Tanzanian specimens as Amblyomma marmoreum , based on Walker et al. (2003), a publication that does not include information for morphologically identifying this species. Mohammed et al. (2020) found Amblyomma marmoreum in Nigeria, a record that requires confirmation, and that country is not included within the range of this tick. Okely et al. (2022) state that Amblyomma marmoreum has been found in Egypt but maintain that it is not established in that country.

Amblyomma marmoreum is the principal member of a species complex that is thought by Guglielmone et al. (2017) to probably include more species than currently recognized. Some specimens of Amblyomma marmoreum may have been confused with Amblyomma sparsum , Amblyomma nuttalli or Amblyomma falsomarmoreum , and vice versa. Additionally, in Theiler & Salisbury (1959) there are disagreements between the text descriptions of the nymphs of three species from the Amblyomma marmoreum complex ( Amblyomma marmoreum , Amblyomma nuttalli and Amblyomma sparsum ) and the corresponding figures ( Tarragona et al. 2021).
