Notes on some tardigrades from South Africa, with the description of Diphascon (Diphascon) zaniewi sp. nov. (Eutardigrada : Hypsibiidae)

Five species of eutardigrades are reported from South Africa. One of them Diphascon (Diphascon) zaniewi sp. nov. is new for science. It belongs to the pingue group but differs from all species of this group by having a very narrow buccal tube (0.9 μm [ptd 4.9]) and second macroplacoid is the same length as the first one. Besides, it differs from each species of the group in some other morphological characters. Other species reported here are: Hypsibius maculatus, H. convergens, Macrobiotus cf. richtersi, Minibiotus intermedius.
