The oribatid mite genus Sadocepheus Aoki, 1965 is recorded for the first time from the Philippines; one new species is described from the leaf litter of secondary forest in Mindanao Island. Sadocepheus donvictorianoensis Ermilov & Corpuz-Raros sp. nov. differs from the most similar species, S. elevatus Mahunka, 1987 by the larger body size, long medial and short lateral teeth of the lamellae and shorter adanal setae. Revised generic diagnosis and the data on distribution and ecology of Sadocepheus species are presented.

The oribatid mite genus Gephyrazetes (Oribatida, Mochlozetidae) is recorded for the first time in the Ethiopian region; one new species is described from soil and litter of Korup National Park in Cameroon. Gephyrazetes umukusumae sp. nov. differs from G. fasciatus Hirauchi, 1999 by the larger body size, truncate lamellar cusps, setiform bothridial setae, very small notogastral porose areas, paraanal position of adanal lyrifissures, presence of four pairs of genital setae and tuberculate lateral parts of prodorsum, and absence of dorsosejugal and sublamellar porose areas. Revised generic diagnosis and the data on distribution and ecology of Gephyrazetes species are presented.

AbstractSpecies of the oribatid mite genus Tegeocranellus from North and Central America are discussed, and immatures are described for the first time. Six new species are described and keyed: Tegeocranellus alas from Costa Rica, T. barbarae from Alabama, Mississippi, and Florida, T. kethleyi from Alabama and Mississippi, T. mississippii from Louisiana and Texas, T. muscorum known from Ontario to Florida, and T. mediolamellatus from Guatemala. Descriptions of T. alas, T. barbarae, T. mediolamellatus, and T. muscorum are based on adults and immatures, and those of the other two species on adults only. I expand the generic diagnosis to include information on the apheredermous, plicate immatures, and present a character analysis hypothesizing that the monogeneric family Tegeocranellidae is a member of the Ameronothroidea, closely related to Selenoribatidae and Fortuyniidae.

The genus Kalloia (Oribatida, Carabodidae) is recorded in the Oriental region for the first time. A new species — Kalloia gerdweigmanni n. sp. — is described from litter of oil palm plantations and jungle rubber agroforests from Sumatra, Indonesia. It differs from Kalloia simpliseta Mahunka, 1985 by the presence of a transverse ridge in the mediodistal part of the lamellae, translamella and two thick, diagonal, convergent ridges forming a triangular structure in the medioanterior part of the notogaster, and by the localization of notogastral setae da, dm, la, lm, lp and h1. The generic status of Kalloia is discussed and supported. Kalloia mahunkai Pérez-Íñigo and Baggio, 1989 and Machadocepheus foveolatus Mahunka, 1978, which were considered representatives of Kalloia, are removed from this genus and combined preliminarily in Gibbicepheus. Revised generic diagnosis and data on ecology and distribution of known species of Kalloia are presented.

The oribatid mite genus Dorycranosus (Oribatida, Liacaridae) is recorded for the first time from the Neotropical region. One new species, Dorycranosus grenadaensis sp. nov. is described from ferns and mosses near lake in the forest of Grenada (Antilles). The new species differs from Dorycranosus shipitsyni (Ermilov, Rybalov & Kemal, 2011) by the body surface, length of notogastral and adanal setae.

A new species of the genus Hardybodes (Oribatida, Carabodidae) is described from the nest of an unknown species of ants (Formicidae) in soil in Luzon Island, Philippines. Hardybodes minutus n. sp. differs from all species of the genus by the localization of notogastral setae (lm and h2 inserted in the same longitudinal rowdorsocentrally together with da, dm, dp, lp and h1 versus lm and h2 in dorsolateral positions and da, dm, dp, lp and h1 inserted in dorsocentral positions in the other species). Revised generic diagnosis and an identification key to the four known species of Hardybodes are presented.

The oribatid mite genus Eurhynchoribates (Oribatida, Rhynchoribatidae) is recorded in the Philippines for the first time. Two new species are described from litter and soil of secondary forests. Eurhynchoribates samarensis sp. nov. differs from all species of the genus by the presence of 14 pairs of notogastral setae, and is designated as type species of the new subgenus Orinchobates subgen. nov. Eurhynchoribates (Eurhynchoribates) misamisensis sp. nov. is morphologically similar to E. (Eurhynchoribates) obtusus (Mahunka, 1985), but differs by the smaller body size, rostral setae clearly longer than lamellar setae, all barbed, and the presence of two transverse ridges between antero-lateral concavities on the prodorsum. The inclusion of Eurhynchoribates orientalis (Balogh, 1970) in the subgenus Orinchobates is proposed.

The oribatid mite genus Crassoribatula is recorded in the Neotropical region for the first time. One new arboreal species—Crassoribatula biobioensis sp. nov.—is described from twigs of olivillo tree in Chile; it differs from the type species—Crassoribatula maculosa—by the length of exobothridial and notogastral setae. The tritonymphal instar of the new species is described (the first data on juveniles in this genus). The systematic placement of Crassoribatula is discussed, resulting in transfer from Oribatulidae (Oripodoidea) to Maudheimiidae (Ceratozetoidea). A revised generic diagnosis for Crassoribatula is presented.

This work includes taxonomic and faunistic data on the oribatid mite genus Phyllhermannia (Oribatida, Hermanniidae) in Taiwan. One new species is described on the basis of adult specimens; Phyllhermannia shikongensis sp. nov. differs from all species of the genus by the presence of prodorsal hump on the prodorsum. Phyllhermannia pulchra Aoki, 1973 is recorded in the Oriental region for the first time; this species is redescribed and its main morphological traits are summarized. An identification key to species of Phyllhermannia of Taiwan and adjacent continental territory (China) is provided.

A new species of the genus Aokiella (Oribatida, Carabodidae) is described from soil of Taiwan. Aokiella liaoi sp. nov. differs from Aokiella xuansoni Vu, Ermilov & Dao, 2010 in that notogastral setae c1 and c2 as well as da and la are similar in length, and the surface of the notogaster has small, sparse foveoles. A revised generic diagnosis, an identification key to known species, and data on the distribution and ecology of Aokiella are presented.

Ocesobates (Oribatida, Chamobatidae) is recorded in the Oriental region for the first time; a new species of this genus is described from soil, ferns, lichens and gramineous weeds of Taiwan. Ocesobates ziweiensis sp. nov. differs from other Ocesobates-species by the presence of translamella (versus translamella absent). A revised generic diagnosis and an identification key to known species of Ocesobates are presented. Ocesobates bregetovae Shaldybina, 1974 is proposed as a junior subjective synonym of Ocesobates boedvarssoni (Sellnick, 1974). Ocesobates galaicus Subías & Shtanchaeva, 2012 is moved to the genus Globozetes Sellnick, 1928.
