27. Dermacentor panamensis Apanaskevich & Bermúdez, 2013 .

Neotropical: 1) Costa Rica, 2) Guatemala, 3) Honduras, 4) Nicaragua, 5) Panama (Apanaskevich & Bermúdez 2013, Guglielmone et al. 2021).

Fairchild et al. (1966) hypothesized that more than one species may exist under the name Dermacentor halli . This view was confirmed by Apanaskevich & Bermúdez (2013), who found that all records of Dermacentor halli from Central America correspond to a new species named Dermacentor panamensis, and that the figures of Dermacentor halli in Yunker et al. (1986) in fact depict Dermacentor panamensis .
