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.

Two species of oribatid mites (Acari: Oribatida), Pergalumna pseudosejugalis sp. nov. and Oribatella gerdweigmanni sp. nov. are described from Bu Gia Map National Park (Southern Vietnam). Pergalumna pseudosejugalis sp. nov. is most similar morphologically to P. crassipora Mahunka, 1995, but it differs from the latter in the microfoveolate integument, presence of pseudosejugal line, of a pair of transversal striate bands on ventral side and of median pore, and by shorter lamellar setae. Oribatella gerdweigmanni sp. nov. is most similar morphologically to O. sculpturata Mahunka, 1987, but it differs from the latter in a smaller body size, a microfoveolate integument, the presence of the translamella, more short lateral and medial lamellar dens, and sparse striae in an epimeral region.

Three new species of oribatid mites of the genus Protoribates (Oribatida, Haplozetidae) are described based on adult specimens from the Tam Dao National Park of Northern Vietnam. Protoribates chistyakovi sp. nov. differs from P. sangumburiensis (Choi, 1996) by being larger, the localization of lamellar setae, and morphology of rostrum and interlamellar setae. Protoribates shaldybinae sp. nov. differs from P. dentatus (Berlese, 1883) by its distinctly foveolate body surface, morphology of pedotecta II and leg tarsi I and II, and much longer adanal setae ad2. Protoribates shvanderovi sp. nov. differs from P. gracilis (Aoki, 1982) by its larger body size, localization of lamellar setae, and the relative lengths of lamellar, interlamellar and bothridial setae, and longer dorsophragmata.

Pergalumna jenoi sp. nov. differs from P. margaritata Mahunka, 1989 and P. pseudomargaritata Mahunka, 1994 by the presence of simple dorsosejugal suture, dentate anterior margin of the ventral plate, distinct reticulate pattern on the pteromorphs and dense stria on the genital plates, the localization of setal alveoli la posterior to porose areas Aa, and the absence of a median pore. Pergalumna tuberclesejugalis sp. nov. differs from P. margaritata and P. pseudomargaritata by the larger body size, the localization of porose areas Aa closer to lm than la, and setal alveoli h3 close and lateral to A2, the presence of sejugal porose areas, and the absence of a median pore and stria on the genital plates. Pergalumna grebennikovi sp. nov. differs from P. bifissurata Hammer, 1972 by the larger body size, the presence of smooth bothridial setae, well-developed interlamellar setae, reticulate anterior margin of pteromorphs, comparatively long prodorsal median ridge and a median pore, and the localization of setal alveoli la and porose areas Aa.

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.

(Maculergithus) tamdao subgen. et sp. nov. and G. (Maculergithus) luteomaculatus subgen. et sp. nov. from Tam Dao National Park in North Vietnam. Two more species from Hainan, China, G. multipunctatus Che, Zhang & Wang, 2007 and G. nonomaculatus Meng & Wang, 2012 are also placed in Maculergithus subgen. nov. A fifth species from Hainan, yet undescribed and erroneously identified as G. multipunctatus in recent papers also belongs to this new subgenus. Illustrations of habitus, morphological details and male genitalia together with a distribution map and an identification key to the species of Maculergithus subgen. nov. are provided. Four species of the genus Gergithus are now recorded in Vietnam. A rectificative note on the misinterpretation of G. multipunctatus in recent publications on Issidae is also provided.

Two new species of the genus Eutegaeus (Oribatida, Eutegaeidae) are described based on specimens from moss in the Queulat National Park of Chile. Eutegaeus aysenensis sp. nov. (description based on the adult, larva, deuto- and tritonymph) is morphologically similar to that of Eutegaeus lagrecai in having long, flagellate interlamellar and notogastral setae and rod-like bothridial seta; it differs from the latter by having smaller body size and comparatively long bothridial seta, the lamella having anteromedial process, and by the absence of striate ornamentation on notogaster. Eutegaeus queulatensis sp. nov. (description based on the adult, proto- and tritonymph) is morphologically similar to that of Eutegaeus membraniger in having a triangular anteromedial lamellar process, long, rod-like bothridial seta, foveate lamella, and dorsal notogastral setae of medium length; it differs from the latter by having smaller body length, thickened notogastral setae, flagellate interlamellar setae, setiform lamellar setae, a tubercle on epimere III, and absence of an anterolateral tooth on the lamella. Based on new information, several characters in the generic diagnosis of Eutegaeus adults are modified or expanded, and a preliminary diagnosis for juveniles is presented. The larva of E. aysenensis sp. nov. is the first to be described for the genus. Nymphs of four species of Eutegaeus are compared.
