Ixodes boliviensis Neumann, 1904 . Neotropical: 1) Belize , 2) Bolivia , 3) Colombia , 4) Costa Rica , 5) Ecuador , 6) Guatemala , 7) Honduras , 8) Mexico (south), 9) Nicaragua , 10) Panama , 11) Peru ( Cooley & Kohls 1945 , Blair et al. 2004 , Álvarez et al. 2005 , Guzmán-Cornejo & Robbins 2010 , Bermúdez et al. 2015 a , Pesquera et al. 2015, Guglielmone et al. 2021 ). Camicas et al. (1998) treated Ixodes boliviensis as a synonym of Ixodes diversifossus . The two species are similar, but a morphological comparison of types has not been undertaken, and these taxa are considered provisionally valid here. Additionally, many records of Ixodes boliviensis have been published under the name Ixodes bicornis according to Kohls (1956c) , who synonymized this name under Ixodes boliviensis , a decision that was hardly justified according to Guglielmone et al. (2021) , who treat this synonymy as tentatively valid. Bermúdez et al. (2021) found important molecular differences between specimens from Panama , named as Ixodes cf. boliviensis , and Ecuador . Consequently, the range of Ixodes boliviensis is also provisional because a reexamination of the types of Ixodes boliviensis and Ixodes bicornis is needed to confirm the opinion of Kohls (1956c) .
