Amblyoma tigrinum

Amblyomma tigrinum, Amblyomma maculatum and Amblyomma triste are morphologically similar species, but adults of Amblyomma tigrinum are relatively easy to separate from those of its relatives (Nava et al. 2017), although morphologically differentiating the larvae and nymphs of these three species is extremely difficult (Estrada-Peña et al. 2005). Mexico was included within the geographic distribution of Amblyomma tigrinum by Graham et al. (1975), but no bona fide specimens of this tick have been collected in Mexico (Guzmán-Cornejo et al. 2011). Kolonin (2009) listed Guyana within the range of Amblyomma tigrinum, but no Guyanan records of this tick have been found. The Colombian records of Amblyomma tigrinum in Acevedo-Gutiérrez et al. (2020) require confirmation (Guglielmone et al. 2021), and Colombia is provisionally excluded from the range of this tick. Keirans (1982) listed four records of Amblyomma maculatum from Argentina, but these are, in fact, Amblyomma tigrinum, as discussed in Guglielmone et al. (2003).
