112. Amblyomma scutatum Neumann, 1899 .

Nearctic: 1) Mexico (north); Neotropical: 1) Costa Rica, 2) El Salvador, 3) Guatemala, 4) Honduras, 5) Mexico (south), 6) Nicaragua ( Maes et al. 1989 as Amblyomma scutalum , a lapsus, Alvarez et al. 2005, Voltzit 2007, Guzmán-Cornejo et al. 2011, Guglielmone et al. 2021, Romero et al. 2021).

The larva and nymph of Amblyomma scutatum were described under the name Amblyomma boneti , a provisional synonym of Amblyomma scutatum in Guglielmone et al. (2021).

Authors differ in their morphological definition of Amblyomma scutatum ( Guglielmone et al. 2020) , which also renders range statements uncertain.

Camicas et al. (1998) and Guglielmone et al. (2003, 2014) regarded this tick as Neotropical, but Guzmán-Cornejo et al. (2011) reported Amblyomma scutatum based on specimens collected in the Nearctic portion of Mexico.

Neumann (1899) described the male and female of Amblyomma scutatum from specimens collected in Guatemala. The nymph of this tick was not described in Neumann (1899) or in subsequent studies, but Neumann (1899) classified as Amblyomma scutatum nymphs from Brazil and Paraguay, although these specimens were treated as doubtful from Robinson (1926) to Nava et al. (2017), and Guglielmone et al. (2015) deemed unreliable the Venezuelan records of Amblyomma scutatum in Fiasson (1949) and Díaz Ungría (1957). Kelehear et al. (2017a) included French Guiana within the range of Amblyomma scutatum but provided no information to support their claim. Oliveira et al. (2014) allegedly found Amblyomma scutatum in Brazil, but these records were treated as doubtful in Guglielmone et al. (2021). Consequently, South America is considered to be outside the geographic range of Amblyomma scutatum .
