Secondary sclerotization formed by the en- larged and fiised basal sclerites of the acetabula. Hence: acetabula neither below genital flaps (as in Bandakiinae, Anisitsiellinae) nor fused "onto" the genital flaps (as in most other Limnesiidae).

Derivatio nominis This genus Shivatonia gen. nov. hopefully helps to modify the old approach to the Anisitsiellidae-Lim- nesiidae complex and opens the field to new concepts. Similarly, in one of his aspects the Hindu god Shiva is the one who allows progress and perpetuation through destruction. The suffix "-tonia" is often used as sufipDc in the "anisitsiellidTike" mites. Species included Shivatonia acetabulensis sp. nov. is the only known spe- cies of the genus. Nymphs, males and females were collected from mosses in two brooklets situated a few kilometers from each other near Rimbik (Darjeeling, India. Coll.: 1993-06-02_l, 1993-06-02_2). Inventory (adults): DS/VS. Dorsum with one large posterior and another large anterior shield. Organization of plates, glands and setae in dorsal and ventral shields with differences between males, females and nymphs as given for Bharatonia and in the description of the subfamily. In. FIG. 46. Shivatonia acetabulensis s'p. nov. (female). Right: dorsum.
