Ixodes fossulatus Neumann, 1899 . Neotropical: 1) Ecuador ( Guglielmone et al. 2021 ) Ixodes fossulatus was treated as a doubtful species in Clifford et al. (1973) but is considered valid in Camicas et al. (1998) and Guglielmone et al. (2014), among others, and here. The alleged presence of Ixodes fossulatus in Japan resulted from a diagnostic error, as discussed in Yamaguti et al. (1971) .
