The present checklist of the oribatid mites compiles all known published records of Ecuador with 479 species belonging to 232 genera and 89 families; 180 of these species were described from Ecuador. Oribatid mites were found in 15 of the 24 provinces that conform the Ecuadorian territory. In the provinces of Zamora Chinchipe, Galápagos, Loja, Cotopaxi, Pichincha and Napo, 95% of the species were recorded. 23.6% of these species are known only from Ecuador, 47.8% are distributed in Neotropical region, the remaining are Pantropical, semicosmopolitan and cosmopolitan. This high number of species makes Ecuador the country with the second largest number of species records in Latin America after Brazil.

The genus Mesoplophora (Acari: Oribatida: Mesoplophoridae) was represented only by two species in China prior to this work. In this study, a new species, Mesoplophora (Parplophora) vestigia sp. n., is described from Dali Bai Autonomous Prefecture, Yunnan Province. New localities and some remarks on the two known species from China are presented. A world key to species of the genus is provided to facilitate the further study on this group.

This checklist of the oribatid fauna of Canada and Alaska (excluding Astigmata) includes 580 identified species in 249 genera and 96 families. The known fauna of Canada includes 556 identified species in 247 genera, and that of Alaska includes 182 species in 95 genera; 39 of the 42 oribatid superfamilies are represented. We further list ~ 300 species that are currently unidentified, and possibly undescribed. In addition, we list 42 genera that are represented only by unidentified and probably undescribed species. For each species we give combinations and synonymies, specific locations in Alaska and the Provinces and Territories of Canada, habitats, and biogeography. There are 182 identified species known for Alaska, 152 for Yukon, 122 for Northwest Territories, 58 for Nunavut; 210 for British Columbia, 213 for Alberta, 15 for Saskatchewan, 84 for Manitoba, 167 for Ontario, 210 for Québec, 110 for Nova Scotia, 77 for New Brunswick, 84 for Newfoundland and 6 for Prince Edward Island. The known fauna of Canada is smaller than that of Austria, and is approximately equivalent to that of the Czech Republic. As these countries are much smaller in size than Canada and less ecologically diverse, we consider the Canadian and Alaskan fauna are at most 25% known. The paucity of these data reflects the absence of taxonomic and faunistic studies on Oribatida in State, Provinces or Territories, and especially in the Canadian and Alaskan National Park systems and the hundreds of Provincial Parks. Despite the almost 90% increase in described species since the catalogue of Marshall et al. (1987), there is a need for focussed, coordinated research on Oribatida in the natural regions throughout Canada and Alaska, and for monographs on families and genera with large numbers of undescribed species, such as Brachychthoniidae, Damaeidae, Cepheidae, Liacaridae, Oppiidae, Suctobelbidae, Hydrozetidae, Phenopelopidae, Scheloribatidae, Haplozetidae and Galumnidae.

A checklist of the oribatid mite species reported in Brazil is presented, including all published records up to 2015. A total of 576 described species in 206 genera and 83 families is presented. Information includes the names by which each species was reported in the Brazilian literature, its general known distribution and by Brazilian States, references, and remarks, when needed. As with most countries, there was a slow early accumulation of knowledge but in recent decades the pace of description has been relatively high. A graphical overview of the number of described oribatid mite species from Brazil in different decades is given. The proportion contributed by each of the major oribatid groups is generally similar to that of the overall world fauna, with a composition that reflects the South American fauna and all of the Neotropics in general. There is a relatively low percentage of primitive mites (Palaeosomata, Enarthronota) other than Lohmanniidae and Mesoplophoridae, which are quite diverse. The Brachypylina comprises about 68% of the oribatid mite fauna. In the checklist, 41% of the species are known only from Brazil, 37% from the Neotropical region, 13.5% have a wider distribution in the global tropical and subtropical regions, and 8.5% are considered cosmopolitan or semicosmopolitan species. The number of descriptions of new species since 2000 from Brazil (73 spp.) and South America (230) is high, but the oribatid mite fauna of these countries remains poorly known. Only continued studies can determine if the high number of species known only from Brazil is an indication of high endemism.

This monograph sums up the state of knowledge of ptyctimous mites fauna of Tanzania on the basis of literature data. Diagnoses of 61 species known from Tanzania (TAN) are given, 15 species have been redescribed on the basis of types and 22 species have been redescribed in earlier papers. One new species: A. ( H.) onkos sp. nov. is described. For each species a morphological diagnosis and geographic distribution are given. Eight species are new to TAN, including one new to the Afrotropical Region. Keys for identification of species and higher taxa are given. The fauna of ptyctimous mites of Tanzania (TAN) shows some differences and specificities as well as some similarities to the fauna of the nearby hotspot Madagascar with neighbouring islands (MAG), to that of the Afrotropical Region and even to that of distanced faunas of other zoogeographic regions of the southern hemisphere. The fauna of TAN comprises slightly more genera and subgenera (19) than that of MAG (18), although the number of species in MAG is much higher (111) than in TAN (61 species). The specious higher taxa are: Pocsia, Plonaphacarus and Notophthiracarus. Pocsia is represented by the highest number (10) of species found in the Afrotropical Region, and it is likely this subgenus originates from Tanzania (7 endemic species). Plonaphacarus is relatively rich in species in the Oriental Region. Notophthiracarus is even more speciose in the fauna of MAG and the Australasian Region. Over a half of the species known from Tanzania (37) were found in the material collected in 2010 from the Uluguru and Nguru Mts. Both these mountain ranges show some specificity of fauna. Two species occur only in the Nguru range, while as many as 7 species are endemites in the Uluguru.

Mesoplophora (Parplophora) pulchra Sellnick, 1928 (Fig. 4 A-C) Diagnosis — Measurements of the specimens from sample TAN-014: Prodorsum: length 182, width and height 144, setae: ss 73, in 68, le and ro 63, ex 10; notogaster: length 242, width 202, height 156, setae: c 1 and e 1 73, c 3 43; genital plate 56×28, anal plate 33×35, distance between genital and anal plates 20. Small-sized species; colour yellow. Prodorsum with pointed rostrum; sensilli long, filiform with head slightly fusiform; other setae simple; interlamellar setae the longest but thinner than lamellar and rostral setae; exobothridial setae the finest, shorter than diameter of bothridia. Setae of notogaster, except setae c 2 and c 3 covered with some spines; setae c 2 the thinnest and more remote from anterior border than setae c 1 and c 3. Ventral region; formula of epimeral region: 3-1-3-1; 10 pairs of ventral setae present; 7 pairs of genital setae with formulae: 5: 2 and 3 pairs of anal setae present. Chaetome of legs: I: 0-3-3(1)-4(1)-16(3), II: 0-4-3(1)- 3(1)-13(1), III: 2-2-2(1)-2(1)-10, IV: 2-2-0-8; tarsi monodactylous. Locality in Tanzania: Uluguru Mts. Species new to TAN and Afrotropical Region. Remark — All characters of the specimen from TAN-014 are the same as in the description. I found only setae c 3 of notogaster finest and shortest than other notogastral setae. Distribution — Western Palaearctic, distributed in Central Europe, Maghreb countries, Anatolian and Iranian areas. It is surprising to find this Western Palaearctic species in Tanzania., Published as part of Niedbała, Wojciech, 2017, Ptyctimous mites (Acari, Oribatida) of Tanzania, pp. 957-1072 in Acarologia 57 (4) on page 965, DOI: 10.24349/acarologia/20174217, http://zenodo.org/record/5402635

Mesoplophoridae: Mesoplophora (M.) parapulchra Niedbała, 2012 Distribution: Australian; Queensland, New South Wales, Victoria.

Diagnoses of 111 ptyctimous species known from Madagascar and neighbouring islands Seychelles, Mauritius, Comoros and Reunion (MAG) are presented. Additionally, 44 species have been redescribed based on type material. Four species are new for the Afrotropical Region, and nine are new for MAG. Keys for identification of species and higher taxa have also been constructed. The percentage ratio of Protoplophoridae to Archoplophoridae: Mesoplophoridae: Euphthiracaroidea is 2: 5: 27: 66. The proportions of species representing two families – the more primitive Oribotritiidae and less primitive Euphthiracaridae of Euphthiracaroidea are similar. Within Phthiracaroidea the more primitive Phthiracaridae are less abundant than Steganacaridae. Among Euphthiracaridea the most abundant are the genera: Oribotritia and Acrotritia, while from among Phthiracaroidea by far the most abundant species is the genus Notophthiracarus, while Hoplophorella and Phthiracarus are also rather abundant. The proportions of the number of species from higher taxa are usually similar to those in the fauna of other zoogeographic regions in the southern hemisphere. The fauna of MAG is characterised by a high number of related species (88), endemic 68 (61 %) and indigenous 20 (18%) as well as a relatively high number of pantropical species (11). All these proportions of species are similar to other zoogeographic Regions of the southern hemisphere: Afrotropical, Oriental, Australasian and Neotropical. The fauna of MAG (111 species) is closer to that of the Afrotropical Region (200 species) (15% common species) than to that of the Oriental Region (262 species) (4% common species). A significant number of widespread species (14) occur in the faunas of MAG and the Oriental Region, and four of them seem to be of Oriental origin. The fauna of Madagascar and neighbouring islands shows no similarity to that of India. In 171 soil samples collected in 2010-2015 on Madagascar the number of species found was 78. The eastern part of the island is the most abundant in species – 67 species; the northern part is less abundant – 53 species and, central part is the least abundant – 34 species. The highest number of endemites was found in the fauna of the eastern and central parts of Madagascar. The unique character of Madagascan fauna is the presence of a high number of endemic species among the dominant species and species of high frequency. In the new material the most abundant and most frequent species is the endemic Oribotritia striata, followed by five endemic species Protophthiracarus araios, Oribotritia mahunkai, Indotritia paulyi, Notophthiracarus similis, Notophthiracarus zebrus and two pantropical species Acrotritia vestita and Indotritia javensis. The fauna of neighbouring islands does not show an Oriental origin and is closely related to that of Madagascar, more than half of the number of species (17) occur also in Madagascar but nearly a quarter of the species are endemites. The fauna of MAG has been compared 12 years after the former report, some similarities and differences were found.

Mesoplophoridae Ewing, 1917 Cuticle smooth; with fine, irregular microsculpture. "Notogaster" of adults represented by joined CDE segments with eight pairs of setae, segments FHP joined with adanal segments. Genital and anal plates separated; 7-9 pairs of genital setae, adults with transverse scissure dividing genital plates into two parts, anterior with one to two pairs of setae, posterior with five to eight pairs of setae; seven to 10 pairs of "ventral" setae; two to four pairs of anal setae.

Mesoplophora (Mesoplophora) heterotricha sp. nov. (Figs 3A���C) Diagnosis. Surface of body punctate; lateral carinae of prodorsum absent; sensilli, lamellar and interlamellar setae long, thick and smooth; rostral setae thin; exobothridial setae minute, shorter than diameter of bothridia; in���in>ro��� ro; ���notogastral��� setae similar in shape as interlamellar setae, except setae c 3 thin; Setae h of mentum shorter than distance between them; formula of genital setae 6: 1; eight pairs of ventral setae unequal in length; ���ano-adanal��� plates with two pairs of smooth setae. Description. Measurements. Holotype: Prodorsum: length 195, width 135, height 82, setae: ss 108, ro 40, le 65, in 80, ex 4; mutual distance: in���in 85, le���le 126, ro���ro 75; ���notogaster���: length 302, width 260, height 252; setae: c 1 88, c 2 82, c 3 50, c p 72, d 1 90, d 2 90, e 1 80, e 2 70; ventral region: an 1 20, an 2 20; genito-aggenital plate 65��35, ���ano-adanal��� plate 70��30. Paratypes (n=3): Prodorsum: length 200���205, width 135���142, height 85���88; ���notogaster���: length 310���320, width 255���265, height 250���255. Integument. Colour yellowish. Surface of body punctate. Prodorsum (Figs 3 A ���B). Lateral carinae absent; sensilli (ss) long, thick, smooth and pointed distally; interlamellar and lamellar setae (in and le) long, thick and smooth; rostral setae (ro) thin and smooth; exobothridial setae (ex) minute, shorter than diameter of bothridia; comparative length: ss>in>le>ro>ex; mutual distance of setae: le���le > in���in>ro���ro. ���Notogaster��� (Fig. 3 A). 8 pairs ���notogastral��� setae present, all long (c 1/ c 1��� d 1���0.9), thick and smooth, except setae c 3 shorter and much thinner; setae c 1��� c 3 form almost equally spaced row. Ventral region (Figs 3 A, C). Setae h of mentum shorter than distance between them. Seven pairs of genital setae (g) with formula: 6: 1; ventral plate with eight pairs of setae unequal in length; ���ano-adanal��� plates with two pairs of smooth setae. Legs. Chaetotaxy of legs complete; setal counts for leg segments: I: 0-3-3(2)-4(1)-15(3); II: 0-4-2(1)-2(1)- 13(2), III: 2-3-2(1)-2(1)-10, IV: 2-3-2-2-8; tarsi monodactylous. Material examined. Holotype: adult (NIGA, in alcohol), CHINA, Hainan Province, Lingshui, from litter under Alsophila sp., 15 May 2013, leg. Yuting Huang. Paratypes: 1 adult (NIGA, in alcohol), same data as holotype; 2 adults (NIGA, in alcohol), from moss in the tree hole, other data same as holotype. Type deposition. Type specimens are deposited in NIGA. Etymology. The new specific name ��� heterotricha ��� refers to the different shapes of prodorsal and ���notogastral��� setae. Remarks. This new species is close to Mesoplophora (M.) frogneri Niedbała, 2004 from Sarawak, Malaysia in having similar shape of sensilli, most prodorsal and ���notogastral��� setae; exobothridial setae shorter than diameter of bothridia; lamellar setae situated closer to interlamellar setae; in���in>ro���ro; eight pairs of ventral setae present; aggenital position without setae; and formula of genital setae 6:1. However, this new species can be easily distinguished by: (1) lateral carinae of prodorsum absent (versus present in M. (M.) frogneri); (2) rostral setae much thinner than interlamellar setae (versus similar in shape as interlamellar setae); (3) setae c 3 much thinner than other ���notogastral��� setae (versus similar in shape); (4) setae c 1��� c 3 form almost equally spaced row (versus setae c 3 closer to anterior border)., Published as part of Liu, Dong, 2016, Mesoplophoroidea (Acari, Oribatida) of China, pp. 519-539 in Zootaxa 4084 (4) on pages 525-526, DOI: 10.11646/zootaxa.4084.4.4, http://zenodo.org/record/1052321
