Amblyomma cruciferum Neumann, 1901 . Neotropical: 1) Haiti , 2) Puerto Rico ( Bequaert 1932 b , Guglielmone et al. 2021). Voltzit (2007) listed a Puerto Rican locality for Amblyomma cruciferum as being Brazilian, a lapsus. Morel (1967) treated Amblyomma torrei as a synonym of Amblyomma cruciferum . There are morphological discrepancies in the descriptions and redescriptions of Amblyomma cruciferum , and Guglielmone et al. (2003) have suggested that a comparison of type specimens of Amblyomma cruciferum and Amblyomma torrei would help in characterizing these species, while Barros-Battesti et al. (2009) stated that the two species are morphologically similar but differ in scutal ornamentation. For these reasons, data concerning Amblyomma cruciferum should be considered cautiously.
