Ixodes nitens Neumann, 1904 . Oriental: 1) Christmas Island ( Keirans 1985c ). Nuttall & Warburton (1911) stated that Ixodes nitens was collected on Christmas Island , supposedly in the Pacific Ocean, but this locality was later corrected by Keirans (1985b) , who stated that Christmas Island is located in the Indian Ocean. This island is an Australian territory near Sumatra ( Indonesia ). James et al. (2019) described how the only known specimens of Ixodes nitens were obtained from the last specimens of Rattus macleari collected before this rodent became extinct in about 1904, it therefore being unlikely that Ixodes nitens exists on Christmas Island today.
