(Figs. 4, 5, 15–19, Table 2) Type material. Holotype: sex indeterminate, slide number 89 (22). Collected by Dr. P. I. Krylov (Zoological Institute of the Russian Academy of Sciences, St. Petersburg) 15.12. 1985, King George Island, Antarctica. Paratypes: slide’s numbers 89 (1, 5, 17, 18, 19, 23) from the same locality. Type locality: Antarctica, King George Island, vicinity of Henryka Arctowskiego Polish polar station, moss in a little stream from under snowfield. 27 adult and juvenile specimens and 1 exuvium with three eggs were found. Etymology. This species is named after the region of its type locality, Antarctica. Description. Large animals, exact body length could not be measured, because of the strong constriction during fixation (even in constricted condition it exceed 800 µm), colour of the fixed specimens reddishbrown; cuticle smooth; eyes present. Six peribuccal and two lateral papillae present. Mouth with 6 peribuccal lamellae longitudinally striped in their basal portion. Buccal tube wide and long. Claws large, massive. Main branch of each claw with two well developed accessory points. Complex basal claw+secondary branch with well developed rounded basal thickening. First three pairs of legs with elongated cuticular thickening near the claw bases. All dimensions are given in Table 2. Smooth eggs (white in incident light, colourless in preparation) deposited within exuviae. No mature males were found. Differential Diagnosis. Milnesium antarcticum sp. nov. differs from Milnesium reticulatum by having smooth cuticle without gibbosities, more caudal position of the insertion point of the stylet supports (pt value 70.0– 73.7 in M. antarcticum sp. nov. and 68.5–69.8 in M. reticulatum), claws with developed basal spurs on the outer claws and larger pt ratio of the length of main branches of the claws of the IV pair of legs (49.8–55.9 in M. antarcticum sp. nov. and 41.7–44.3 in M. reticulatum).
