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 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.

The otocepheid oribatid mite genus Leptotocepheus Balogh, 1961 is recorded in the Australasian region for the first time. The taxonomic status of the genera Leptotocepheus Balogh, 1961 and Longocepheus Balogh & Mahunka,1966 is discussed, resulting in the recognition of Longocepheus as a subgenus (stat. nov.) of Leptotocepheus and the following recombinations: Leptotocepheus (Longocepheus) australis (Balogh & Mahunka, 1966) comb. nov., Leptotocepheus (Longocepheus) globosus (Grobler, 1995) comb. nov., Leptotocepheus (Longocepheus) longus (Balogh, 1961) comb. nov., Leptotocepheus (Longocepheus) youngai (Mahunka, 1984) comb. nov. A new species of Leptotocepheus (Longocepheus) is described from New Zealand, Leptotocepheus (Longocepheus) neozealandicus sp. nov., which differs from other species of the subgenus by the presence of short, slightly developed prodorsal costulae. Revised generic and subgeneric diagnoses, an identification key and distributions for the known taxa of Leptotocepheus are presented.

The present study is based on oribatid mite material (Acari, Oribatida) collected from Tam Dao National Park (Northern Vietnam) in 1988. A list of identified taxa, including 119 species from 80 genera and 47 families, is presented; of these, 13 species (Epilohmannoides rabori, Camisia spinifer, Sadocepheus undulatus, Eremobelba flexuosa, Hammerella excisa, Suctobelbella inenodabilis, Dolicheremaeus auritus, Eupelops acromios, Protoribates genitalis, Allogalumna machadoi, Carinogalumna philippinensis, Pergalumna magnipora capillaris, Galumnella nipponica) and five genera (Epilohmannoides, Camisia, Sadocepheus, Brassiella, Carinogalumna) are recorded in the Vietnamese fauna for the first time, and two species (Tokunocepheus mizusawai, Flagellozetes (Cosmogalumna) ornatus), one genus (Tokunocepheus) and one family (Tokunocepheidae) are recorded in the Oriental region for the first time. Two new species are described: Ramusella paraarcuata sp. nov. differs from Ramusella arcuata Mahunka & Mahunka-Papp, 2012 by the larger body size, lamellar setae similar in length and thickness to interlamellar setae, the presence of two or three branches on bothridial setae, and the absence of notogastral setae c. Neoribates paragracilis sp. nov. differs from Neoribates gracilis Travé, 1972 by the larger body size, and the presence of long apex (not shorter than head) on bothridial setae.

The present study is based on oribatid mite materials (Acari, Oribatida) collected from Taiwan in 2017. A list of identified taxa, including 109 species/subspecies, 84 genera and 48 families, is presented; of these, 50 species/subspecies, 28 genera and 7 families are recorded for the first time in the fauna of this country, and 8 species and 1 genus are recorded for the first time in the Oriental region. A new species belonging to the genus Lohmannia (Lohmanniidae) is described from soil of the Yangmingshan National Park; L. douhua Ermilov sp. nov. differs from L. pseudoturcmenica Ermilov, 2017 by the broadly phylliform posterior exobothridial setae, narrowly phylliform rostral, epimeral and genital setae and clearly longer notogastral setae. An identification key to the known species of Lohmannia from the Oriental region is presented.

The oribatid mite family Liacaridae (Acari, Oribatida) is recorded in Vietnam for the first time. Two new species of liacarids of the genera Liacarus and Xenillus are described from Tam Dao National Park, northern Vietnam. Liacarus vietnamensis sp. nov. is similar to L. laterostris Mihelčič, 1954 in the morphology of lamellar cusps (inner teeth well-developed; interlamellar tubercle absent) and in having long interlamellar setae and short notogastral setae, but differs by the directions of lamellar cusps and morphology of bothridial setae. Xenillus tamdaoensis sp. nov. is similar to X. longipilus Pérez-Íñigo & Peña, 1995 in having long notogastral setae, insertion of notogastral setae lm posterior to la, and the presence of an interlamellar tubercle, but differs by the morphology and position of lamellar cusps, size of the interlamellar tubercle and length of interlamellar setae.
