Abstract
The oribatid mite genus Oribotritia Jacot, 1924 (Oribotritiidae) is reviewed. A new species of Oribotritia collected from
litter in Hunchun, China, Oribotritia hunchunensis sp. nov., is described and figured. Four species, Oribotritia angusta
Mahunka, 1982, Oribotritia asiatica Hammer, 1977, Oribotritia chichijimensis Aoki, 1980, Oribotritia gigas Bayoumi &
Mahunka, 1979, are redescribed based on Chinese specimens. Oribotritia nepalensis Niedbała, 2000 is considered as a
new junior subjective synonym of Oribotritia gigas Bayoumi & Mahunka, 1979. A comprehensive, fully annotated and
referenced checklist of all known species and a key to known Chinese species of this genus are provided to facilitate to

Introduction
As type genus of the family Oribotritiidae, Oribotritia has a complicated history. Berlese (1883) proposed the
genus Tritia which was preoccupied by Tritia Risso, 1826 (a genus in the molluscan family Alectrionidae). Jacot
(1924) proposed Oribotritia as a replacement name for Tritia Berlese, 1883 and still used Hoplophora decumana
C. L. Koch, 1836 as the type species. Michael (1898) was convinced that this type was misidentified and indicated
that it should be Phthiracarus berlesei Michael, 1898. His view was supported by following authors (e.g. van der
Hammen 1959, Märkel 1964). However, this was further complicated by the fact that the presumed type specimen
of P. b e rl es ei could not be found in Berlese’s “Acarotheca Italica” (Märkel 1964, p. 29, citing van der Hammen).
Fortunately, some P. berlesei specimens from Berlese’s “Acarotheca Italica” were preserved in the Rijksmuseum
van Natuurlijke Historie, Leiden. So Märkel (1964) designated a lectotype female from this series for this genus.
Oribotritia species collectively have a nearly cosmopolitan distribution except for their absence in the
Antarctic region. According to my tally, 90 valid species and one subspecies have been reported prior to this work.
While studying the long-term oribatid collections of Northeast Institute of Geography and Agroecology, Chinese
Academy of Sciences and National Zoological Museum of China, Institute of Zoology, Chinese Academy of
Sciences, we identified five species of Oribotritia, including a new species. Some remarks on features are provided
based on these Chinese materials. Oribotritia nepalensis Niedbała, 2000 is considered as a new junior subjective
synonym of Oribotritia gigas Bayoumi & Mahunka, 1979. In addition, a comprehensive, annotated and
informative fully referenced world checklist of Oribotritia species and a key to known Chinese species are
provided to facilitate to the further research, because the existing world checklists are either incomplete or lacking
references (e.g. Subías 2004), and comprehensive data is scattered through multiple publications.
Material and methods
Measurements and descriptions are based on specimens mounted in temporary cavity slides that were studied using
a light microscope equipped with a drawing attachment.

Terminology generally follows Niedbała (2000, 2011). The unit of measurement is micrometre (μm).
Holotype and one paratype are deposited in the Northeast Institute of Geography and Agroecology, Chinese
Academy of Sciences, Changchun (NIGA). One paratype is deposited in the National Zoological Museum of
China, Institute of Zoology, Chinese Academy of Sciences, Beijing (ZMCAS). Other specimens are split between
NIGA and ZMCAS.

REVIEW OF ORIBOTRITIA
Notogaster (Fig. 1A). Notogastral setae fairly short (c

≈0.5), similar in shape to rostral setae, setae c
3
are
the smallest; setae c
2
further away from anterior border than setae c
1
and c
3
.
Ventral region (Figs 1A, C–G). Setae h of mentum considerably longer than distance between them; setation of
palps: 0-3-0-3-9(1); epimeral setal formula: 3-0-2-2. Nine pairs of genital setae (g) arranged with formula: 7:2; two
pairs of aggenital setae located longitudinally, setae ag
2
longer than ag
1
; three pairs of anal and three pairs of adanal
setae present, all minute; setae ad
3
situated between level of setae an
2
and an
3;
lyrifissures iad placed between level
of setae ad
3
and an
3
.
Legs (Figs 1H). Setal counts for leg segments: 1-4-5(2)-5(1)-22(3); II: 1-4-4(1)-5(1)-21(2), III: 3-2-3(1)-4(1)-
15, IV: 3-2-2(1)-3(1)-14; femora I with distinct distal spines; setae d on femora I near distal end.
Material examined. Holotype: 1 adult (NIGA, in alcohol), China: Jilin Province, Yabian, Hunchun, from litter
under tree, 3 Apr. 2015, leg. Dong Liu. Paratypes: 2 adults (NIGA, in alcohol), same data as holotype.
Etymology. The new specific name “hunchunensis” refers to the type locality, Hunchun in Jilin Province,
China.
Remarks. This species is very large. It distinguishable from congeners by presence of two pairs of prodorsal
lateral carinae (upper ones composed with about three lines, lower ones short), stout and rough interlamellar,
rostral and notogastral setae, fine and smooth lamellar, three pairs of anal and three pairs of adanal setae,
lyrifissures iad placed anterior to setae ad
3
, and femora I with distinct distal spines.
Compared with O. asiatica Hammer, 1977, these two species are similar in having rigid, erect interlamellar,
rostral and notogastral setae, similar shape of sensilli, three pairs of anal and adanal setae, but this new species can
be differed by the following features: 1) two pairs of lateral carinae on prodorsum (versus one pair in O. asiatica);
2) setae c
2
further away from anterior border than setae c
1
and c
3
(versus setae c
1
and c
2
more so); 3) interlamellar,
rostral and notogastral setae rough (versus sparsely barbed); 4) aggenital setae longer (versus minute); 5)
lyrifissures iad placed anterior to setae ad
3
(versus at the level of setae ad
2
or between setae ad
2
and ad
3
); 6) femora
I with distinct distal spines (versus without).
It is also similar to O. gigas Bayoumi & Mahunka, 1979 in having rigid, erect interlamellar, rostral and
notogastral setae, similar shape of sensilli, but this new species can be distinguished by 1) two pairs of lateral
carinae on prodorsum (versus one pair in O. gigas); 2) interlamellar, rostral and notogastral setae rough (versus
sparsely barbed); 3) nine pairs of genital setae (versus eight pairs); 4) aggenital setae longer (versus minute); 5)
three pairs of anal setae (versus one or two pairs); 6) femora I with distinct distal spines (versus without).

Remarks. Compared with the original description of holotype and redescription of specimens from Nepal,
some characters vary in this species: 1) length of prodorsal setae: e.g. length of exobothridial setae (ex>le in Jilin
Province, but ex<le in Sichuan Province and Nepal); length of sensilli (longest in Sichuan, shortest in Nepal). 2)
number of barbules of setae (densely barbed in Jilin, sparsely barbed in others); 3) length of notogastral setae
(c

); 4) epimeral setal (3-0-2-2 or 3-0-2-3 in Jilin); 5) number of aggenital setae
(two or three pairs in Jilin); 6) number of anal setae (one or two pairs in Sichuan); 7) setal counts of legs.
The genus Oribotritia is not easy to deal with as there are few reliable morphological features. This species is
very similar to O. asiatica. As mentioned above (see remarks on O. asiatica), the number of genital setae of O.
asiatica varied (eight pairs in Chinese specimens versus nine pairs in type specimen), so they are distinguished
only by the number of anal setae (one or two pairs in O. gigas versus three pairs in O. asiatica). Although the
character “one or two pairs anal setae versus three pairs of anal setae” may be a reliable difference, molecular
methods may be needed to help resolve the issue.
The species O. gigas and O. nepalensis, both recorded in Nepal, have nearly the same shape and size, and are
similar in other morphological characters; they differ only in setation of epimera and palps. Niedbała (2000)
inferred that they may have same origin and may have been subjected to relatively recent adaptative radiation. In
my opinion, setation of epimera and palps are difficult traits to study, especially in Oribotritia species, because they
usually have a dark cuticule and tightly bundled legs which make setation of epimera and palps very hard to be
observed and counted. Many descriptions of Oribotritia species actually did not include or inaccurately include
these data. In addition, I have found some examples of the varied setation of epimera and palps in some species or
even between sides of a single specimen (see example in Jilin Province and remarks on O. chichijimensis).
Therefore, Oribotritia nepalensis Niedbała, 2000 is probably conspecific with O. gigas.
