Guglielmone, Alberto A., Petney, Trevor N. & Robbins, Richard G., 2020, Ixodidae (Acari: Ixodoidea): descriptions and redescriptions of all known species from 1758 to December 31, 2019, Zootaxa 4871 (1), pp. 1-322 : 79-80

2. Amblyomma albopictum Neumann, 1899 .

A Neotropical species, all of whose parasitic stages are usually found on Squamata : Iguanidae ; adults and nymphs have been collected from Squamata : Boidae . Durden et al. (2015) found larvae and nymphs on Squamata : Tropiduridae . There are no records of Amblyomma albopictum causing human parasitism.

M: Lucas (1852), under the name Ixodes variegatus and given its actual status in Neumann (1899)

F: Vigueras (1934); see note below

N: undescribed

L: Černý (1969b)

Redescriptions

M: Robinson (1926), Clifford and Kohls (1962), Onofrio et al. (2006b), Voltzit (2007), Barros-Battesti et al. (2009); see note below

F: Clifford and Kohls (1962), Onofrio et al. (2006b), Voltzit (2007), Barros-Battesti et al. (2009); see note below L: none

Note: Guglielmone et al. (2003), based mostly on Černý (1969b), detail variations in morphological descriptions of this species, concluding that Amblyomma albopictum is poorly defined and that more than one species may exist under this name. This problem is particularly evident with the female of Amblyomma albopictum because Vigueras (1934) described the female without providing illustrations, and the first redescription in Clifford and Kohls (1962) contains discordances between the figures and text, where it is stated that coxa I possesses a bluntly rounded internal spur, while the accompanying figure shows only an external spur, in agreement with Vigueras (1934). Thereafter the male and female of Amblyomma albopictum were redescribed by Voltzit (2007) and Barros-Battesti et al. (2009), and in each paper the description of the female disagrees with that in Clifford and Kohls (1962), while the descriptions of both sexes in Voltzit (2007) differ slightly from those in Barros-Battesti et al. (2009). It seems that the above authors have described different species under the same name, an indication of the need to reexamine the morphology of Amblyomma albopictum , focusing on its populations and type specimens. With this in mind, the host records listed above should be considered provisionally valid.
