14. Dermacentor halli MacIntosh, 1931 .

Nearctic: 1) Mexico (north), 2) USA; Neotropical: 1) Mexico (south) (Apanaskevich & Bermúdez 2013, Guzmán Cornejo et al. 2016, Guglielmone et al. 2021).

Apanaskevich & Bermúdez (2013) stated that the figures of Dermacentor halli in Yunker et al. (1986) correspond to Dermacentor panamensis .

Records of Dermacentor halli from Costa Rica, Guatemala and Panama were all reclassified as Dermacentor panamensis by Apanaskevich & Bermúdez (2013), confirming the view of Fairchild et al. (1966), who found morphological differences between Dermacentor halli specimens collected in Central America and those found in North America.
