description: Genus Micherdzinskiiobovella Hirschmann, 1989   
 Micherdzinskiiobovella Hirschmann, 1989: 136.   
 Uroobovella micherdzinskii ­group – Hirschmann, 1989: 136.   
 Type species. Uroobovella micherdzinskii Hirschmann et ZIRNGIEBL-NICOL, 1972 by original designation.   
 Diagnosis. Idiosoma oval, dorsally little domed, marginal and dorsal shields fused anteriorly. All dorsal setae short and smooth. Caudal inner margin of marginal shield undulate. Five pairs of sternal setae smooth and needlelike. Genital shield of female linguliform, anterior margin situated between coxae II. Prestimatid part of peritreme long and M­shaped or divided into a short hook-like and a long V-shaped branches. Poststigmatid part short. Tritosternum with vase-like base, apically serrate, its laciniae subdivided into several branches. Hypostomal setae h1 phylliform, broad in central part, h2 short and robust, h3 and h4 narrow, smooth or marginally serrate. Palptrochanter setae v1 serrate, v2 smooth or serrate. Corniculi small and horn-like, internal malae short and smooth. Movable digit of chelicerae shorter than fixed digit, both digits bearing a small central tooth. Internal sclerotized node associated with levanton tendon present. Leg I with ambulacral claws; leg setae smooth.   
 Remarks. The phylliform and centrally broaded hypostomal setae h1 is a very rarely observed character within the Uropodina mites. Similar character state is also visible on the species of the genus Trigonuropoda Trägårdh, 1952 sensu lato (see HIRSCHMANN 1993), especially in the species of Trigonuropoda difoveolata ­group (HIRSCHMANN & HIRAMATSU 1990 a). These species have strongly sclerotized idiosoma, the inner margin of marginal shield undulate, and the setae h1 apically wider than the central part. On the other hand, the cillibid species, Australlocilliba kuchtaorum Athias-Binche et Błoszyk, 1988 has also similar hypostomal h1 setae. The Australlocilliba kuchtaorum species belongs to the family Cillibidae, where the internal sclerotized node associated with levanton tendon is absent on chelicerae, and species of this genus bears anterior process on female genital shield, contrary to the Micherdzinskiiobovella species, where female genital shields do not have any apical processes.   
 Notes. This genus was not listed in HALLIDAY’s (2015) catalogue of the Uropodina genera.However, when HISCHMANN (1989) listed all species in the description of Uroobovella micherdzinskii ­group and description of the genus Micherdzinskiiobovella, only the type species were explicitly mentioned as members of this genus, therefore, we list all of the other species here as new combinations.
