The genus Setoxylobates (Oribatida, Haplozetidae) is recorded in Taiwan for the first time; one new species of this genus is described based on adults from soil of mountain tea farm in Taiwan. Setoxylobates taigangensis Ermilov sp. nov. differs from Setoxylobates foveolatus Balogh & Mahunka, 1967 in having smaller body size and setiform bothridial setae, and the absence of foveolae on the body. Revised generic diagnosis and an identification key to known species of Setoxylobates are provided. The taxonomic status and systematic placement of some related poronotic taxa are discussed, resulting in the following new taxonomic proposals: Protoribates Berlese, 1908 (=Lignobates Mahunka, 2006 syn. nov.); Setoxylobates Balogh & Mahunka, 1967 (=Plenoxylobates Hammer, 1979 syn. nov.). A new species name is proposed: Protoribates mahunkasandori Ermilov nom. nov. (=Lignobates berndhauseri Mahunka, 2006, preoccupied by Mahunka 1993). The initial generic status of Polyxylobates Hammer, 1973 and the position of Perxylobates mayuloeus Corpuz-Raros, 1979 in Perxylobates are supported.

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.

A new species of Lamellarea (Oribatida, Lamellareidae) is described from hick twigs of southern live oak in Florida, U.S.A. (part of the Neotropical region). Lamellarea americana sp. nov. differs from most similar species, Lamellarea digitata and L. forceps by the ventrally inserted lamellar setae, the number of genital setae, the length of interlamellar setae, and the body size. Remarks on generic diagnosis and distribution of Lamellarea are presented.

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.

A new species of Eremella Berlese, 1913 (Oribatida, Eremellidae) is described from a termite nest of Cornitermes silvestrii Emerson in Snyder, 1949 (Isoptera, Termitidae) in Brazil. Eremella vazdemelloi sp. nov. differs from Eremella ensifera Balogh and Mahunka, 1968 by the presence of short notogastral setae, the bothridial setae specifically directed posterolaterally, and the absence of tutorial ridges. Revised generic diagnosis and an identification key to known species of Eremella are presented. The taxonomic status of the eremellid genera Licnocepheus Woolley, 1969, Triteremella Kunst, 1971 and Afreremella Mahunka, 1973 are discussed, resulting in the following new taxonomic proposals: Eremella (=Licnocepheus syn. nov.), Eremella (=Triteremella syn. nov.), Eremella reticulatus (Woolley, 1969) comb. nov. (from Licnocepheus), Eremella simpliseta (Mahunka, 2011) comb. nov. (from Triteremella). Also, the generic status of Afreremella and Archeremella Balogh and Mahunka, 1974, and initial systematic placement of Afreremella luisiae Mahunka, 1973, Eremella kaszabi Csiszár, 1962 and Eremella matildebellae Mahunka and Palacios-Vargas, 1995 are supported.

Two genera (Faiga Dworakowska 1980 and Sikkimasca Dworakowska 1994) are reported for the first time from China, and the type species of these genera are re-illustrated.

A New Species

A new species of free-living nematode Monhystera tibetica sp. nov. from a thermal spring in the Garuda Valley at an altitude of 4249 m in Western Tibet is described. The general morphology corresponds to the generic diagnosis. The cephalic setae are very short. In the lower part of the stoma there is a small denticle. The amphid of males is situated over the level of the denticle. The distance from the edge of the head to the denticle is about 6 μm. The amphid of females is situated above the denticle. The esophagus is dilated at the base, pseudobulbus width is 22 μm. Males have numerous precloacal supplements. From the geographically close species of M. curvicaudata Tsalolikhin, 1915 the new species is distinguished by body size, amphid position, position of the vulva and the presence of the stomal denticle. From M. wangi Wu et Hoeppli, 1929 the new species differs by the amphid position and the presence of the stromal denticle. From M. shibrui Eyualem et Coomans, 1996 the new species differs in body size and length of spicules. The taxonomic status of the species with one and two denticles is discussed. The replacement of the name Tridentulus with Tridentula is no longer relevant. The validity of the name Tridentulus Eyualem et Coomans, 1995 is maintained.

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

The genus Lobellina is reported from China for the first time by a new species, Lobellina nanjingensis, described here. The species is assigned Lobellina because most, but not all, characters comply with the diagnosis of the genus given by Deharveng and Weiner (1984). It is suggested that the generic diagnosis needs to be slightly modified to take account of the characters of the new species. Lobellina nanjingensis sp. nov. differs from all known members of the genus in the specific character of 5+5 setae on ventral tube. It is similar to the Korean species L. paraminuta Deharveng and Weiner, 1984 in the structure of mandible and maxilla, the presence of cephalic seta O, the number of setae on tubercle Di of Abd. V and the number of dorsal tubercles on Abd. V. However, it is easily distinguished from the latter species by the body colour, the number of ventral tube setae, the structure of macrosetae, the type of cephalic seta O and the number of ocular setae.

Four species of freshwater crabs from three genera and two families (CantopotamonhengqinenseHuang, Ahyong & Shih, 2017,NanhaipotamonguangdongenseDai, 1997,Nanhaipotamonmacausp. n., andSomanniathelphusazanklonNg & Dudgeon, 1992) are documented from Macau for the first time. One new species,Nanhaipotamonmacausp. n., is described. The large flap on the male first gonopod terminal segment sets it apart from all other known congeners exceptN.wupingenseCheng, Yang, Zhong & Li, 2003, from Fujian. Characters of the carapace, male first gonopod and size, however, clearly differentiate these two species. Preliminary genetic studies also suggest that the two are not closely related. A neotype is designated forN.wupingense. The taxonomic status ofNanhaipotamonguangdongenseis also discussed. Notes on the general biology and conservation status of these crabs are also included.

The present study is based on oribatid mite materials collected from Mozambique in 2019. A list of identified taxa, including 53 species/subspecies from 44 genera and 28 families is provided. Of these, six species are new to science, all other taxa are recorded for the first time in the Mozambican fauna. One new species, Galumnella mikhailovi Ermilov sp. nov., is described herein: it is similar to G. csavasorum in the presence of setiform, unilaterally spinose bothridial setae and rugose notogaster, but differs in smaller body size, the presence of monodactylous legs and rounded rostrum, as well as in the absence of sublamellar line and rugose sculpturing in the anogenital region.
