23. Dermacentor andersoni Stiles, 1908 .

ND: ND, Vegetation (Gordillo-Pérez et al. 2009; Guzmán-Cornejo et al. 2016).

Note: This tick species has a Nearctic distribution; however, the only record that exists for the state of Tamaulipas is that of Gordillo-Pérez et al. (2009), based on nymphs, so its presence in this state is tentative, and requires confirmation through new collections.
