... The family includes two genera: Epimerella Kulijev, 1967; and Enisella Ayyildiz and Luxton, 1989. Subias (2009 considered the rather specific Indonesian genus Luxtonia Mahunka, 2001 also the member of Epimerellidae (see Discussion section below). ...
... First record of the genus and species from Crimean peninsula. Mahunka (2001) described the genus Luxtonia from Borneo, with Luxtonia hauseri Mahunka, 2001 as type species, and he placed it in the newly described family Luxtoniidae Mahunka, 2001. Subías (2004 did not support the independence of the new family and included Luxtonia in Epimerellidae. ...

A new species of the genus Epimerella (Oribatida, Epimerellidae), E. kalmykorum n. sp., is described, based on materials collected from the reed debris in the bank of the salty Manych-Gudilo Lake in the Republic of Kalmykia, Russia. The morphology of gnathosoma and the identification of leg setae and solenidia are given for the first time for any representative of Epimerellidae. Besides, Enisella turcica Ayyildiz and Luxton, 1989 is first found in Crimea (on the shore of the saline Sivash Lake). Generic diagnoses for Epimerella Kulijev, 1967 and Enisella Ayyildiz and Luxton, 1989 are revised. An identification key, distribution and habitats of all known representatives of Epimerellidae are presented.
... Eremaeozetes hanswursti Mahunka 1999 from Singapore is a Retrozetes based on the following character states and is hereby recombined: 1) in lateral view the notogaster is wedge-shaped and deepest posteriorly and the circumgastric scissure is clearly visible; 2) the centrodosal region with an oval area; 3) the humeral region and cerotegument of humeral regions strongly triangular (cf. Fig. 12 of Mahunka, 1999 and Fig. 15 herein); 3) the marginal arrangement of the notogastral setae except the centrodorsal lm and the presence of a saccule medial to seta lp; 4) the genital setae are aligned longitudinally: g 1 is not displaced laterally as in Eremaeozetes; 5) the configuration of the lamellae with a central, expanded notch and medially-opposed lamellar setae in dorsal view and reflexed (though covered in cerotegument) in lateral view ; 6) the large anal setae each at the far ends of the plate, curved and covered in thick cerotegument; 7) its small size, 152-158 Female. Cerotegument: reticulate pattern of cells densely covering prodorsum, notogaster and ventral surface; oval centrodorsal region bare (Fig. 11a). ...
... Notogaster strongly convex in lateral view; notogaster waisted anteriorly in region of pteromorphs; lenticulus strongly protuberant and positioned anteriorly on notogaster; dorsosejugal suture indistinct (Fig. 18) Lamellae extremely long, extending well beyond rostrum, strongly recurved apically; tutorium prominent, projecting; setae ad 2-3 positioned close together near lateral curve of ventral plate; dorsosejugal suture transverse; bounded laterally by conical apophyses of setae c 2 positioned on reduced dorsosejugal lobes (Fig. 11) Posterior prodorsum with median V-shaped projection; dorsosejugal suture transverse or bowed; lenticulus positioned some distance posterior of dorsosejugal suture (Fig. 9) Apices of lamellae S-shaped: curved posteriorly, then recurved anteriorly; median sclerotised bands of lamellar cuticle forming Y-shaped structure dorsally (Fig. 15) Apex of rostrum visible in dorsal orientation, with acute projection; stalk of bothridial seta recurved; apices of lamellae separated by drop-shaped fissure (Fig. 17) (Mahunka, 1999) -Larger species (≥350 μ m long), rostral setae short, thin, straight, without thick cerotegument; head of bothridial seta narrow, elongate, expanding apically; setae ad 2-3 positioned close together lateral of anal plates (Fig. 11) . . . . . R. koghisensis sp. ...
Four new species of Eremaeozetidae are described from Australia: Eremaeozetes schatzi sp. nov. and E. darwinensis sp. nov. from the Northern Territory; E. malleensis sp. nov. from South Australia, and Rogerzetes samueli sp. nov. from Norfolk Island. Eremaeozetes spathulatus Balogh, 1968 from Papua New Guinea is recombined to Rogerzetes. Eremaeozetes undulatus Mahunka 1985 sensu Aoki 2006 from the Ryukyu Islands is a previously undescribed species. It is differentiated from E. undulatus Mahunka 1985 from St. Lucia and named Eremaeozetes aokii sp. nov. Retrozetes gen. nov. is proposed, containing the type species, R. koghisensis sp. nov., R. mirabilis sp. nov. and R. novaecaledoniae sp. nov. from New Caledonia, as well as R. fernandezi sp. nov. from Papua New Guinea. Eremaeozetes hanswursti Mahunka, 1999 from Singapore is recombined to Retrozetes. A new species of Idiozetes, I. hagenensis sp. nov., is described from Papua New Guinea. Idiozetidae is considered to be a junior synonym of Eremaeozetidae, which is re-defined and contains the genera Eremaeozetes, Idiozetes, Mahunkaia, Retrozetes and Rogerzetes. Seteremaeozetes P. Balogh, 1988 is made a junior subjective synonym of Eremaeozetes. Keys are provided to the genera of Eremaeozetidae and species of Retrozetes. A basic synthesis is presented of the biogeography of the Eremaeozetidae of the south-west Pacific region.
... Among Eremobelba species, the largest is E. bellicosa Balogh & Mahunka, 1967, and smallest is E. porcella Mahunka, 2001, and the body length of most species overlaps (Table 5). In most species, the prodorsal seta in is either long or of medium size, but in few species it is short. ...
The morphological ontogeny of Eremobelba geographica Berlese, 1908 is described and illustrated. This species was investigated mainly in ecological and biological aspects. It inhabits forest soils and cultivated areas, but is not abundant, and adults dominate in extracted samples. In the juveniles, the prodorsal seta in is short, and the bothridial seta is setiform. The nymphs are quadrideficient and eupheredermous, i.e. they carry exuvial scalps of the previous instars, using a cornicle. Paraproctal setae occur in all juvenile instars, which is rare in Brachypylina, and hypertrichy occurs in the aggenital region of the deutonymph, tritonymph and adult, and adanal region of the adult. In all instars, seta d on all genua and tibiae is present, except for tibia I of adult.
A supplement to the monograph on ptyctimous mites of Oriental Region (NIEDBA£A 2000), presents diagnoses of the species described in the papers published after 1998 and a few species described in the papers published before this year. Analysis of a few dozen samples with ptyctimous mites from different areas of Oriental Region has enriched the number of species from the region by 7 species new to science. These new species are: Mesoplophora (Mesoplophora) frogneri n. sp., Apoplophora kapiti n. sp., Apoplophora sarawaki n. sp., Apoplophora serrata n. sp., Apoplophora triquetra n. sp., Austrotritia singaporensis n. sp., and Phthiracarus pondoklowii n. sp. The species Euphthiracarus meghalayensis SANYAL, 1988 has been declared conspecific with Euphthiracarus pakistanensis HAMMER, 1977 and Pthiracarus (Archiphthiracarus) hirsutus FUJIKAWA, 2003 with Phthiracarus setosus (BANKS, 1895). From among the 39 already known species, 12 were known only from the original description and these have been subjected to detailed morphological analysis revealing or allowing more accurate specification of some morphological features, included in the redescriptions presented in this paper. New localities have been specified for the following species: O. chichijimensis, E. meghalayensis, P. globosus, and A.(A.) clavatus, extending their hitherto geographical ranges. In total the supplement presents 45 species, including 8 Mesoplophoridae, 16 Euphthiracaroidea, and 21 Phthiracaroidea.
A new genus and species is described from the tropical rain-forest Reserve of Bukit Timah in Singapore: Singabodes rarus gen. n., sp. n. (Carabodidae). Additional remarks on Bukitritia timah Mahunka, 1990 are given.
