113. Amblyomma scutatum Neumann, 1899 .

A Neotropical species with a few records from the Nearctic Region ( Guzmán-Cornejo et al., 2011). All parasitic stages are found on Squamata : Iguanidae , and members of this family are the only bona fide hosts of Amblyomma scutatum listed in Guglielmone et al. (2015). This host profile is significantly different from that presented in Guglielmone et al. (2014) after Nava et al. (2017) treated as doubtful records of this species from Paraguay and Brazil, and after Guglielmone et al. (2015) dismissed all Venezuelan records, thereby limiting the range of this tick to Mexico and Central America. There are no records of Amblyomma scutatum causing human parasitism.

Note: differences can be found among the descriptions of adults of Amblyomma scutatum . Thus, Voltzit (2007) states that the scutum of the female is inornate, but other authors describe the female scutum as ornate.Additionally, Robinson (1926) found that coxa II of the male has two spurs, but others have described just a single spur. Hoffman (1946, under the name Amblyomma boneti ) provides a description of the hypostomal dentition that is not entirely in agreement with the descriptions given by other workers. It would seem that Amblyomma scutatum is in need of review.
