MILNESIIDAE Ramazzotti, 1962  

Eutardigrades with paired cephalic papillae and peribuccal papillae ( Fig. 5 View FIGURE 5 B,C). Claws with primary and secondary branches completely separated ( Fig. 5 View FIGURE 5 A).

Two models of bucco-pharyngeal apparatuses can be recognized within the family: the Milnesium   model   and the Limmenius   model   .

Milnesium   model   ( Fig. 5 View FIGURE 5 B,C):

Tube rigid without ventral lamina; apophyses for the insertion of the stylet muscles in the shape of "very short and very flat ridges" symmetrical with respect to the frontal plane and lacking caudal processes. Peribuccal lamellae present (4 or 6).

Limmenius   model   ( Fig. 5 View FIGURE 5 D,E):

Tube subdivided into an anterior, short, rigid portion (buccal tube) without ventral lamina, and a long posterior flexible portion (pharyngeal tube) with a spiral thickening; apophyses for the insertion of the stylet muscles in shape of "very short and very flat ridges" symmetrical with respect to the frontal plane and without caudal processes. Peribuccal lamellae present (6).

Composition: Three genera, Limmenius   , Milnesioides   and Milnesium   belong to the family.
