A new species of the genus Lamellarea (Oribatida, Lamellareidae) is described from nests of the termite Trinervitermes trinervoides (Sjöstedt) in the Franklin Game Reserve (Bloemfontein, South Africa). Lamellarea koki sp. nov. differs from all species of the genus by the following main morphological traits: lamellar cusps triangular, without anteromedial processes, separated; translamella long; rostrum with median indentation; several ridges located near tutoria. A revised generic diagnosis, an identification key to known species, and data on the distribution and ecology of Lamellarea are presented.

A new species of the genus Aokiella (Oribatida, Carabodidae) is described from soil of Taiwan. Aokiella liaoi sp. nov. differs from Aokiella xuansoni Vu, Ermilov & Dao, 2010 in that notogastral setae c1 and c2 as well as da and la are similar in length, and the surface of the notogaster has small, sparse foveoles. A revised generic diagnosis, an identification key to known species, and data on the distribution and ecology of Aokiella are presented.

A new species of the genus Eurostocepheus (Oribatida, Otocepheidae) is described from soil and litter of Tam Dao National Park in Northern Vietnam. Eurostocepheus (Eurostocepheus) wojciechniedbalai sp. nov. is morphologically most similar to E. (E.) mahunkai Mondal & Kundu, 1999 from India in the presence of four pairs of genital setae and medial prodorsal condyles, but differs by the quadrangular, anteromedially excavated lateral notogastral condyles, short interlamellar setae, short notogastral setae c, minute epimeral setae 1a, 2a, 3a, two pairs of epimeral setae on epimere IV, and by the transverse position of the anal setae. Revised generic and subgeneric diagnoses, an identification key to the known taxa, and data on the distribution and ecology of Eurostocepheus are presented.

A new species of Antarctozetes (Oribatida, Ceratozetoidea) is described from the soil in New Zealand based on adult morphology. Antarctozetes mariehammerae sp. nov. differs from Antarctozetes intermedius (Hammer, 1967) by the short rostral setae, very short stalks of bothridial setae, and bidentate lamellar cusps. A revised generic diagnosis is given, Antarctozetes is maintained in Punctoribatidae, although knowledge of juvenile instars is lacking. The relationship of Antarctozetes, Anellozetes, Africoribates and Kilimabates is discussed. Data on habitat and an identification key to known species of Antarctozetes in New Zealand are provided.

A new species of the genus Belloppia (Oribatida, Oppiidae) is described from New Zealand; Belloppia bella sp. nov. differs from all species of the genus by the presence of a distal row of clear barbs on the bothridial heads and the median part of the tripartite rostrum strongly protruding and distinctly longer than the lateral parts. Supplementary descriptions for two species, Belloppia wallworki Hammer, 1968 and B. shealsi Hammer, 1968 are given based on new material from New Zealand. A revised generic diagnosis and an identification key to known species of Belloppia are presented.

A new species of the genus Gittella (Oribatida, Oppiidae) - G. kontschani n. sp. - is described, based on materials collected from upper soil and leaf litter in the primary evergreen lowland rainforest of Amazonian Peru. Generic diagnosis, an identification key, distribution, and habitats of all known species of Gittella are presented.

A new species of Eremella Berlese, 1913 (Oribatida, Eremellidae) is described from a termite nest of Cornitermes silvestrii Emerson in Snyder, 1949 (Isoptera, Termitidae) in Brazil. Eremella vazdemelloi sp. nov. differs from Eremella ensifera Balogh and Mahunka, 1968 by the presence of short notogastral setae, the bothridial setae specifically directed posterolaterally, and the absence of tutorial ridges. Revised generic diagnosis and an identification key to known species of Eremella are presented. The taxonomic status of the eremellid genera Licnocepheus Woolley, 1969, Triteremella Kunst, 1971 and Afreremella Mahunka, 1973 are discussed, resulting in the following new taxonomic proposals: Eremella (=Licnocepheus syn. nov.), Eremella (=Triteremella syn. nov.), Eremella reticulatus (Woolley, 1969) comb. nov. (from Licnocepheus), Eremella simpliseta (Mahunka, 2011) comb. nov. (from Triteremella). Also, the generic status of Afreremella and Archeremella Balogh and Mahunka, 1974, and initial systematic placement of Afreremella luisiae Mahunka, 1973, Eremella kaszabi Csiszár, 1962 and Eremella matildebellae Mahunka and Palacios-Vargas, 1995 are supported.

A new species of the genus Hardybodes (Oribatida, Carabodidae) is described from the nest of an unknown species of ants (Formicidae) in soil in Luzon Island, Philippines. Hardybodes minutus n. sp. differs from all species of the genus by the localization of notogastral setae (lm and h2 inserted in the same longitudinal rowdorsocentrally together with da, dm, dp, lp and h1 versus lm and h2 in dorsolateral positions and da, dm, dp, lp and h1 inserted in dorsocentral positions in the other species). Revised generic diagnosis and an identification key to the four known species of Hardybodes are presented.

A new species of Cerocepheus (Oribatida, Cerocepheidae) is described from rainforest litter in southern Chile. Cerocepheus osornoensis sp. nov. differs from Cerocepheus mirabilis by the smaller body size and the presence of bidentate lamellar cusps. Revised generic diagnosis, data on distribution of Cerocepheus and an identification key to known species of Cerocepheidae are presented.

A new species of the genus Setoppia (Oribatida, Oppiidae) is described from soil of Golden Gate Highlands National Park, South Africa. Setoppia paraquattuor n. sp. differs from Setoppia quattuor in having smaller lateral teeth and incision on the tripartite rostrum, shorter notogastral setae h3 and subequal sized la, lm, lp, and h2 setae. Summarized generic traits, identification key, distribution worldwide and in South Africa, and habitats of all known species of Setoppia are presented.
