A new eutardigrade, Milnesium katarzynae sp. nov. is described from China. The new species differs from the most similar Milnesium reticulatum Pilato et al., 2002 in lacking of gibbosities, stylet supports inserted in less caudal position, absence of eyes. M. katarzynae sp. nov. is similar to specimens of M. tardigradum from New Zealand which have reticular shallow depressions in the cuticle but is clearly different by lacking of eyes and narrower buccal tube (pt = 21.7-26.6 in the new species and pt = 41.9 in the specimens collected in New Zealand).
