Note: see Rhipicephalus gertrudae for a discussion of the difficulties attending morphological identification of the larvae and nymphs of Rhipicephalus follis , Rhipicephalus gertrudae , Rhipicephalus simus and Rhipicephalus tricuspis . Walker et al. (2000) and Horak et al. (2018) emphasize the difficulties involved in morphologically separating adults of Rhipicephalus lunulatus from those of Rhipicephalus tricuspis , and from adults of Rhipicephalus interventus , a species of morphologically intermediate characters. Walker et al. (1988) extensively discuss the taxonomic history of Rhipicephalus tricuspis and Rhipicephalus lunulatus but offer no opinion concerning the descriptions of the larva, nymph and adults of Rhipicephalus tricuspis by Theiler (1947), although they used the same specimens to redescribe this taxon. The descriptions and redescriptions of Rhipicephalus tricuspis by Theiler (1947) are treated as valid here, but other redescriptions, as in Elbl and Anastos (1966c), based on specimens collected in Burundi, Democratic Republic of Congo and Rwanda, where this species does not occur according to Walker et al. (2000), are not included in the above lists. See also Rhipicephalus lunulatus .
