Introduction
Harvestmen (Opiliones) is a group of arachnids wide-
spread in a wide range of different geographical zones
and biotopes. Currently 8707 species of Opilionidae
have been described [Kury et al., 2020], but the species
diversity of this group is estimated at about 10 000
species [Pinto-Da-Rocha et al., 2007].
The first information on harvestmen of Primorsky
Krai appeared in the work by V.V. Redikortsev [1936]
with a description of Metagagrella ussuriensis Rediko-
rtsev, 1936 (now a junior synonym of Melanopa gran-
dis Roewer, 1910). Almost thirty years later, redescrip-
tion of Mit opus mon golicus Roewer, 1912 and
Homolophus arcticus Banks, 1893 (as Euphalangium
albofasciatus (Kulczyński, 1901)) from the «Ussuriysky
Krai» was published in a paper by W. Staręga [1964].
Later, S.I. Ljovuschkin [1972] described Taracus
birsteini (Lyovushkin, 1972) from the Belii Dvorets Cave
(Partizansky Raion). In the «Katalog der Weberknechte
(Opiliones) der Sowjet-Union» by W. Staręga [1978]
only four species were registered from Primorsky Krai:
T. birsteini, M. grandis, M. m. mongolicus, and H.
arcticus (as Egaenus zichyi Kulczyński, 1901). A year
later, I.I. Gritsenko [1979a, b] listed seven species for
this territory: Hamitergum eobium (Redikortsev, 1936)
(as Lophacantus eus), M. grandis (as M. damila and M.
ussuriensis), M. m. mongolicus, H. arcticus (as E. albo-
fasciatum), Oligolophus tienmushanensis Wang, 1941,
Phalangium opilio Linnaeus, 1761, and Bidentolophus
bidens (Simon, 1880) (as E. transbaicalicum). In addi-
tion, Sabacon makinoi Suzuki, 1949 [Gritsenko, 1979a]
as S. habei Suzuki, 1966 was described exclusively based
on juvenile specimens from the Kedrovaya Pad Nature
Reserve. This finding still requires confirmation [Tril-
ikauskas, 2015].
More recent data on harvestmen of Primorsky Krai
are available from the works of A.N. Chemeris [Chemer-
is et al., 1998; Chemeris, 2000], where several species
149
Harvestmen of the Sikhote-Alin and the Far Eastern Marine Biosphere Reserves, Russia
are redescribed and Mitopus morio (Fabricius, 1779)
and Psathyropus tenuipes Koch, 1878 are added to the
regional check-list. The record of Nipponopsalis core-
ana Suzuki, 1966 in Primorsky Krai (high number of
specimens was collected in the vicinity of Vladivostok)
is erroneous and should be referred to T. birsteini
[Schönhofer, 2013].
Another species described from Primorsky Krai was
Sabacon rossopacificus Martens, 2015 from Velikan
Cave (Partizansky Raion) [Martens, 2015]. Caddo agi-
lis Banks, 1892 was recorded in the Sikhote-Alin Nature
Reserve in 2020 [Prokopenko, Sergeev, 2020]. This is
the first species of the family Caddidae registered from
continental part of the Russian Far East. To date, four-
teen species of harvestmen from five families are regis-
tered for Primorsky Krai (Table 1).
Although the opilionid fauna of Primorsky Krai is
relatively well known, data concerning the Sikhote-Alin
State Nature Biosphere Reserve and the Far Eastern
Marine Biosphere Reserve are still missed. Thus, the
present paper increases knowledge on the opilionid
fauna of these protected areas.
Material and methods
This paper is based on study of the 55 mature and
the 14 juvenile harvestmen specimens, collected by the
second author during 2015–2020 field seasons in the
localities listed in Table 2. The material was collected
mainly by hands and by the pitfall traps.
All measurements are in mm. Photographs were tak-
en by USB Digital camera Lens Mount attached to a
Zeiss Primo Star microscope and a MBS-10 stereomi-
croscope. All material is deposited in the personal col-
lection of the first author.
Sikhote-Alin State Nature Biosphere Reserve was
founded in 1935 and is the largest protected nature re-
serve in the coniferous-broadleaved forest belt of Eur-
asia and America. At present it is over 400 000 ha and
extends inland from the coast of the Japan Sea, including
the western and eastern spurs of the Sikhote-Alin moun-
tain range. Mountain slopes of different steepness occu-
py up to 80 % of the reserve’s area [Utenkova, La-
betskaya, 2006; Gromyko, 2010]. Flora of Sikhote-Alin
Nature Reserve includes 1094 species of vascular plants
from 504 genera and 135 families [Pimenova, 2016]. Sig-
nificant altitudinal gradient determines seven altitudinal
zones of vegetation, coastal vegetation, belt of coastal
oak forests, belt of pine-broadleaved forests, fir-spruce
forests, stone-birch forests, belt of cedar shrub, and
mountain-tundra vegetation. Forests of other formations
amount about 25 % of the total area of the forest cover.
Herbal vegetation occupies only about 2 % [Pimenova,
2016]. At present, fires are one of the most important
factors causing the transformation of the vegetation cover
of the reserve [Gromyko, 2010].
Far Eastern Marine Biosphere Reserve was founded
in 1978, and includes a group of islands in the Peter the
Great Bay and sections of the mainland shoreline. The
reserve’s territory is about 64 000 ha, about 98 % of
which belongs to the bay water area. Vegetation cover
of the islands differs significantly from that of the main-
land, due to climatic conditions occur. The islands are
strongly influenced by winter winds, and therefore

creeping forms of tree and shrub vegetation are wide-
spread. In addition, unlike the mainland forests, which
suffer from fires and logging, the human impact on
plant communities in the islands is less pronounced
and the advanced stages of demutation are much great-
er. The islands of the Peter the Great Bay are relatively
small. They located on the continental shelf near the
coast. These islands are spurs of the coastal mountain
rises, which were part of the continent in the Pleis-
tocene, from which they separated between 11 000 and
8 500 years ago. Thus, there is an opportunity to study
the composition and structure of peculiar communities
of terrestrial animals and ways of their adaptation to the
island habitats in a natural experiment [Velizhanin, 1976;
Belyaev, 2013; Legalov, Sergeev, 2018; Sergeev, 2019].
Results and discussion
In toto, eight harvestmen species from five families,
Caddidae (1 species), Sclerosomatidae (3 species) and
Phalangiidae (4 species) were recorded. Opiliofauna of
the Sikhote-Alin Nature Reserve is the most species-
rich and includes seven species (Table 1). Five opilion-
id species were found in the Far Eastern Marine Re-
serve. Only one species, Oligolophus tienmushanensis
(family Phalangiidae), was registered on Russkii Island.
All species are distributed in the Far East, except
Caddo agilis Banks, 1892, also known from North-East
America and Japan.
The annotated check-list of harvestmen of the
Sikhote-Alin Reserve and the Far Eastern Marine Re-
serve is presented below, and brief morphological de-
scription of the rare local species H. albofasciatus is
given.

WCO-Lite (with the word “light” restyled as “lite”) is a slenderer, more agile, online version of WCO, aiming to be a public-ready, authoritative reference for taxonomy of all subtaxa of harvestmen worldwide. WCO-Lite is being developed using an integrated web-based workbench for taxonomists called TaxonWorks (http://taxonworks.org/), created by The Species File Group and many other contributors. This PDF/A document is the companion text (for nomenclatural purposes) of the electronic version 1.0 uploaded to the internet.

An annotated list of 55 species in 35 genera of leaf beetles of the Far Eastern Marine Biosphere Reserve is given. The genus Lythraria Bedel, 1897 and three species, L. salicariae (Paykull, 1800), Longitarsus tabidus tabidus (Fabricius, 1775) and Cassida denticollis Suffrian, 1844), are recorded from the Russian Far East for the first time. The genus Pallasiola Jakobson, 1925 and two species, P. absinthii (Pallas, 1771) and Cassida mongolica Boheman, 1854, are newly recorded from Primorskii krai.

This paper describes 20 new species of the genus Sabacon Simon, 1879 from the Palaearctic region: one from France (S. aigoual n. sp.), twelve from Nepal and partly India (S. schawalleri n. sp., S. maipokhari n. sp., S. relictoides n. sp., S. thakkolanus n. sp., S. rupinala n. sp., S. petarberoni n. sp., S. hinkukhola n. sp., S. sineglandula n. sp., S. nishikawai n. sp., S. beatae n. sp., S. minutissimus n. sp., S. simbuakhola n. sp.), six from China (S. kangding n. sp., S. multiserratus n. sp., S. pauperoserratus n. sp., S. beishanensis n. sp., S. minshanensis n. sp., S. jaegeri n. sp.) and one from Pacific Russia (S. rossopacificus n. sp.). With respect to Sabacon the species set of eastern Nepal and adjoining Indian Sikkim proved to be remarkably diversified. Especially small species (1.4 mm minimum), which are difficult to collect, make this local fauna xtraordinarily rich. All species described here are known from only one or a few additional nearby localities. Exceptions to this general rule are sparse at least within Himalayan species. All Chinese species are known only from the type locality so far. Syntopic occurrences of two species are known from Nepal (Mt. Everest area) and from China (Shaanxi, Taibai Shan). In Nepal, the vertical area belt of all species combined extends from 1900 m to 4600 m, but the belt of single species is largely unknown; that of S. chomolongmae, the most common species, covers 1900 m. The vertical area belts of the two Nepal species groups only slightly overlap: jiriensis- species group (7 species) settles in lower (subtropical) climatic belt, chomolongmae- species group (12 species) beyond in the strictly palaearctic belt. They represent two evolutionary lines. Chinese species include at least two, probably three species groups. One group is widely distributed (7 species) and the other one comprises 2 species (or one each). With respect to genital morphology the new European species (S. aigoual n. sp.) markedly differs from most other European species by its genital morphology.
Article
A key to the members of the subfamily Opilioninae is presented, including the genus Homolophus. That same genus is briefly reviewed, diagnosed, and redescribed based upon a study of approximately half of the described species. Many older museum specimens from the Zoological Institute (Saint-Petersburg, Russia) were identified and all species present were redescribed. A list of the 29 currently accepted species (all from Northeastern and Central Asia) is presented along with a list of another four species that their validity and proper inclusion in the genus are questioned (still need to be investigated extensively). Descriptions and redescriptions with many illustrations are presented for two new species and 15 previously described species of Homolophus: H. albofasciatus (Kulczyński, 1901); H. almasyi (Roewer, 1911); H. andreevae Staręga & Snegovaya, 2008; H. arcticus Banks, 1893; H. asiaticus (Gricenko, 1979a); H. betpakdalensis (Gricenko, 1976); H. charitonovi (Gricenko, 1972); H. chemerisi Staręga & Snegovaya, 2008; H. chevrizovi Staręga & Snegovaya, 2008; H. gobiensis Tsurusaki, Tchemeris & Logunov, 2000; H. kozlovi sp. nov.; H. martensi (Staręga, 1986); H. milkoi sp. nov.; H. nordenskioeldi (L. Koch, 1879a); H. pallens (Kulczyński, 1901); H. silhavyi Staręga & Snegovaya, 2008; H. tibetanus (Roewer, 1911); H. vladimirae (Šilhavý, 1967). New country distributional records are detailed for nine species, not including those for the two new species. Three new combinations with Homolophus (H. almasyi, H. asiaticus, H. charitonovi) are recognized for Opilio almasyi Roewer, 1911, Opilio asiaticus Gricenko, 1979a, and Globipes charitonovi Gricenko, 1972.
