Nearctic: 1) Mexico (north), 2) USA; Neotropical: 1) Costa Rica, 2) Guatemala, 3) Honduras, 4) Mexico (south); 5) Nicaragua ( Becklund 1959, Instituto Intermaericano para la Cooperación en Agricultura 1988, Alvarez et al. 2005, Guzmán-Cornejo et al. 2011, Nava et al. 2014 c, Corn et al. 2016, Ḑttmann et al. 2016, Guglielmone et al. 2021).

Amblyomma tenellum was long treated as a synonym of Amblyomma cajennense . This changed when Nava et al. (2014c) compared the types of Amblyomma tenellum and Amblyomma imitator , described by Kohls (1958), and found them to be identical. Therefore, Amblyomma tenellum was reinstated as a valid species and Amblyomma imitator became its synonym. Most records of Amblyomma tenellum have been published under the name Amblyomma imitator .

Serra-Freire & Mello (2006) stated that Amblyomma tenellum (under the name Amblyomma imitator ) has been found in Brazil. However, this statement was considered unconfirmed by Dantas-Torres et al. (2009), and Brazil is excluded from the geographic distribution of Amblyomma tenellum .
