Two new oribatid mite species, Austrocarabodes (Uluguroides) kluttzi Ermilov, Winchester, Lowman & Wassie sp. nov. (Carabodidae) and Pilobatella lowmanae Ermilov, Winchester & Wassie sp. nov. (Haplozetidae), are described from Afro-montane forests in the northern highlands of Ethiopia. An identification key to all known species of Pilobatella is given. An annotated checklist of identified oribatid mite taxa sampled in this studyis presented. Fourteen species, six genera and three families are recorded for the first time from Ethiopia. © 2012 Systematic & Applied Acarology Society.

In the oribatid mite fauna of Cat Tien National Park (southern Vietnam), we discovered four species, each representating a different genus of the family Nanhermanniidae, and eight species representing four genera of Lohmanniidae. Our records of Cosmohermannia robusta and Masthermannia mammillaris (Nanhermanniidae) are the first for the respective genera from Vietnam; the lohmanniids Meristacarus sundensis, Mixacarus exilis, Papillacarus ramosus and P. cornutus are also newly reported from this country. The morphology of juvenile instars of Cosmohermannia robusta is described and illustrated. The juvenile instars of Cosmohermannia differs from those of Nanhermannia by the morphology of prodorsal and gastronotic setae, the presence two large latero-posterior body apophyses, the epimeral formulae, and the length of some epimeral setae. Diagnoses of juvenile instars of the family Nanhermanniidae and the genus Cosmohermannia are proposed. Papillacarus polygonatus sp. n. is described from dark loamy soil of a lagerstroemia forest; it differs from all other species of the genus by its larger body and three different forms of neotrichous setae. © Acarina 2011.

Three new species of oribatid mites of the superfamily Galumnoidea, Pergalumna cattienica sp. n., P. yurtaevi sp. n. and Galumnella microporosa sp. n., are described from Cat Tien National Park (southern Vietnam).Diagnostic keys to the Vietnamese species of Pergalumna and Asian of Galumnella are presented. © Acarina 2011.

A new oribatid mite genus, Valbehanella gen. nov., with type species, V. freestatensis sp. nov., is proposed and described from South Africa. The genus is tentatively included in Unduloribatidae, and if so would be the first record of this family from the southern hemisphere. Valbehanella gen. nov. can clearly be distinguished from the two other unduloribatid genera by lacking a lenticulus, having differently positioned notogastral setae and thinner cerotegument and simple lamellar cusps. © 2012 Systematic & Applied Acarology Society.

Two new oribatid mite species, Hermannobates bifurcatus sp. nov. (Hermanniellidae) and Xenillus brevisetosus sp. nov. (Liacaridae), are described from Ecuador. Hermannobates bifurcatus sp. nov. is similar to Hermannobates monstruosus Hammer in having the combination of a tuberculate prodorsum, foveolate notogaster, and long setiform prodorsal and exuvial notogastral setae and sensilli. However it clearly differs from the latter by having some bifurcate epimeral setae, the surface of the prodorsum, and the lengths of some notogastral setae. Xenillus brevisetosus sp. nov. is similar to Xenillus davisorum J. & P. Balogh in having the combination of the same body surface sculpture and the morphology of the lamellar complex, sensilli, and prodorsal and notogastral setae. However it clearly differs from the latter by the length of the lamellar cusps, interlamellar setae and notogastral setae h1, and number of genital setae. An identification key to Ecuadorian species of Xenillus is presented. © 2012 Systematic & Applied Acarology Society.

A new species of mites Pediculaster ethiopicus sp. nov. (Acari: Pygmephoridae) is described from the forest litter from Ethiopia. The new species belongs to the "calcaratus" species group along with Pediculaster calcaratus (Mahunka, 1965), Pediculaster ensifer (Savulkina, 1978) and Pediculaster clavipes Mahunka, 1975. Although this species group could be placed in the subgenus Neopediculaster, that subgenus is not supported by apomorphic characters and requires further study. We define the calcaratus group based on apomorphic character states and provide a key to its species. © 2013 Copyright Taylor and Francis Group, LLC.

Two new oribatid mite species of Oppiidae, Gittella ecuadoriensis sp. nov. and Lasiobelba (Antennoppia) chistyakovi sp. nov., are described from Ecuador. Gittella and Lasiobelba are recorded for the first time from Ecuador. Gittella ecuadoriensis sp. nov. differs from all species of the genus by the selective characters (long, setiform and smooth notogastral setae, granulate body surface, sensilli with long cilia, absence of muscle sigilla in interbothridial and epimeral regions). Lasiobelba (Antennoppia) chistyakovi sp. nov. differs from all species of the subgenus by the setiform sensilli with long cilia and localization of lamellar setae nearer to interlamellar setae, than rostral setae. An identification key to all known species of Gittella is presented. © 2012 Taylor & Francis.

In 2009-2010, a total of 99 species, 75 genera and 45 families of oribatid mites in Ethiopia were registered. Of these, 89 species, 55 genera and 26 families are first records for the country. The updated list of oribatids of Ethiopia includes 128 species, 94 genera and 55 families. An annotated checklist oribatid mite taxa of Ethiopia with known distributions is provided.

A new oribatid mite species, Oribatella umaetluisorum sp. nov. (Oribatellidae), is described from Cat Tien National Park (southern Vietnam). It was collected in the dark loamy soil of Lagerstroemia forest. Oribatella umaetluisorum sp. nov. has bidentate rostrum, clavate sensilli, microfoveolate body surface, striate epimeral region, serrate anterior margins of pteromorphs and length of notogastral setae, similar only to Oribatella sculpturata from Vietnam, but these species clearly differ by the body size, integumental ornament, shape of basal part of lamellae and distal part of tutoria and the number of leg claws. An identification key to species of Oribatella of the Oriental region is presented. © 2012 Copyright Taylor and Francis Group, LLC.

A new oribatid mite subgenus, Perscheloribates (Ecuadoribates) subgen. nov., and three new species, Perscheloribates (Ecuadoribates) pentasacculus sp. nov., Fissurobates neotropicus sp. nov. and Mucrobates microsetosus sp. nov., of the family Scheloribatidae are described from Ecuador. The new subgenus differs from Perscheloribates (Perscheloribates) by the number of notogastral sacculi and number of genital setae. Fissurobates and Mucrobates are recorded for the first time in Ecuador. The morphology of gnathosoma and legs are presented for the first time for any member of Fissurobates and Mucrobates. © Fundacja Natura optima dux.
