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. An identification key to the Vietnamese species of the genus Protoribates is given.

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.

A new species of oribatid mite, Scheloribates daoensis sp. nov. is described from grass rhizosphere of meadow in the Tam Dao National Park, Northern Vietnam. It is morphologically most similar to S. striolatus Balogh, 1960, but differs by the body size, the morphology of bothridial setae, the length of circumpedal carinae and the distance between sacculi S1–S1. An identification key to known species/subspecies of striolatus-group of Scheloribates is provided.

Three new species of oribatid mites of the genus Pergalumna (Oribatida, Galumnidae) are described from litter and soil in the Korup National Park (Cameroon). 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. An identification key to the known species of the genus Pergalumna from the Ethiopian region is presented.

The new subgenus Maculergithus subgen. nov. is established to accommodate two new species of the genus Gergithus Stål, 1870 (Issinae, Hemisphaeriini): G. (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.

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.
