Archaeocroton sphenodonti

M: Dumbleton (1943), under the name Aponomma sphenodonti and given its current status in Barker and Burger (2018); see note below F: Dumbleton (1943), under the name Aponomma sphenodonti N: Dumbleton (1943), under the name Aponomma sphenodonti L: Dumbleton (1943), under the name Aponomma sphenodonti Redescriptions M: Dumbleton (1953), Kaufman (1972) and Santos Dias (1993), all under the name Aponomma sphenodonti, Nowak (2010) F: Dumbleton (1953), Kaufman (1972) and Santos Dias (1993), all under the name Aponomma sphenodonti, Siuda (1972) under the name Aponomma ludovici, a synonym of Archaeocroton sphenodonti, Nowak (2010) N: Dumbleton (1953) under the name Aponomma sphenodonti, Siuda (1972) under the name Aponomma ludovici L: Dumbleton (1953) under the name Aponomma sphenodonti, Siuda (1972) under the name Aponomma ludovici Note: Miller et al. (2007) and several other workers found molecular evidence for the inclusion of Archaeocroton (under the name Amblyomma sphenodonti) in a new genus of Ixodidae. Those molecular results support morphological studies showing that this species is an atypical member of the former genus Aponomma (Kaufman, 1972), and the study of Klompen et al. (2002), where “ primitive Aponomma ” (Amblyomma elaphense and Amblyomma sphenodonti at that time) were provisionally included in the genus Amblyomma. Recently, Barker and Burger (2018) created the monotypic genus Archaeocroton for Archaeocroton sphenodonti, which is treated as a probable basal group for the genus Bothriocroton.

An Australasian species, all of whose parasitic stages are usually found on Rhynchocephalia: Sphenodontidae, with a rare record of adults from Squamata: Gekkonidae. There are no records of Archaeocroton sphenodonti causing human parasitism.
