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.

Mite Genus

The genus Pilobatella (Oribatida, Haplozetidae) comprises 10 species, which are distributed in the Palaeotropical region; this includes two new species described herein on the basis of adult specimens sampled from forest leaf litter in Andasibe-Mantadia National Park of eastern Madagascar. Pilobatella mikoi n. sp. is similar to Pilobatella baloghi Mahunka, 2003 in having long interlamellar setae and adanal setae ad1 and ad2, but differs by having monodactylous legs (versus tridactylous) and a bothridial seta that is gradually expanded to a narrow head (versus setiform, without head). Pilobatella kovaci n. sp. is similar to P. mikoi n. sp. in having monodactylous legs, long interlamellar setae and adanal setae ad1 and ad2, but differs by the presence of lineolate notogaster and anogenital region (versus lineolate markings absent), long tutoria (versus tutoria of medium length), rounded trochanters distodorsally (versus pointed) and clearly distanced medial ends of apodemes 2 (versus nearly touching at midline). A revised generic diagnosis and an identification key to known species of Pilobatella 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.

Two new species of oribatid mites of the family Oppiidae collected from leaf litter in Madagascar are described. Ramuselloppia indistincta sp. nov. differs from Ramuselloppia anomala by larger body size, the presence of epimeral tubercles  and comparatively long lamellar, interlamellar and notogastral setae and the absence of costulae and heads of bothridial setae. An identification key to known species of Ramuselloppia is provided. Lanceoppia (Baioppia) rugosa sp. nov. differs from all species of the subgenus by heavily rugose posterior part of the notogaster. The genus Ramuselloppia and subgenus Lanceoppia (Baioppia) are recorded in the Ethiopian region for the first time; the species Multioppia (Hammeroppia) wilsoni is recorded in Madagascar for the first time.

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.
