https://doi.org/10.24349/l0py-4r2bPhytoseiid mites are well-known for their value in biological control of phytophagous mites and small insects, such as thrips and whiteflies. They are considered to play an important ecological role under natural conditions (McMurtry et al., 2013; Wu et al, 2009, 2021). Biodiversity surveys in poorly investigated areas is still an urgent need and might result in the discovery of additional species potentially useful for biological control as well as in the acquisition of information on the biodiversity of these areas (Kreiter et al., 2020a; 2020b, 2020c; Kreiter and Douin, 2021).
Ruyuan Yao Autonomous County is located in the northeast of Guangdong Province, on the south side of Nanling Mountain. It includes Nanling National Nature Reserve and Tianjingshan National Forest Park, considered a biodiversity-rich area, but where the phytoseiid fauna is poorly known (Fang et al., 2020a). The objective of this paper is to present a checklist of the species found in a recent survey in Ruyuan Yao Autonomous County, with the description of the three new species collected.
The survey was conducted in Ruyuan Yao Autonomous County, in Shaoguan City of Guangdong Province, China, in November 10–15, 2021. Collection sites included Nanling National Nature Reserve, Tianjingshan National Forest Park, Ruyuan Grand Canyon, Tongtianluo Virgin Forest, Nanshui Reservoir, Guikeng Village, Bibei Village, Banling Village and Yunxi Village. Table 1 shows the plant species onto which phytoseiid mites were collected in this study, and their respective families.
The mites were collected using the plant-beating method and transferred to vials containing 75% ethanol with a fine brush. They were mounted in Hoyer's medium and examined, measured and illustrated under a phase and DIC (differential interference contrast) microscope (Zeiss® Axio Imager A2) provided with the photographic system ZEN 2.3 (Blue edition) © Carl Zeiss Microscopy GmbH, 2011.
Measurements of the new species are presented in micrometers; for each structure, the measurement of the holotype is given in bold, followed by the mean, and range (in parentheses). Morphological features of adult mites were measured as follows: dorsal shield length and width were taken from the anterior to posterior margins of the shield along the midline and from the lateral margins at s4, s6 and j6 level; for all ventral shields, lengths were measured along their midline from the anterior to posterior margins; widths were taken from the lateral margins at st2, st5 and ZV2 level; cheliceral fixed digit length was measured from the dorsal poroid to the distal tip and movable digit length measured from the basal articulation to the tip. The generic concept adopted in this publication is that of Chant and McMurtry (2007). Idiosomal seta terminology follows that of Lindquist & Evans (1965) as applied to the phytoseiids by Chant & Yoshida-Shaul (1991) and Chant & Yoshida-Shaul (1992), respectively for dorsum and venter; adenotaxy and poroidotaxy terminology follows that of Athias-Henriot (1975), spermathecal apparatus terminology that of Beard (2001) and leg chaetotaxy that of Evans (1963).
All specimens collected, including the type specimens were deposited at IZGAS (Institute of Zoology, Guangdong Academy of Sciences, Guangzhou, China). The world distribution of these species is given according to the Phytoseiidae Database (Demite et al. 2022) and the distribution in China is given according to Wu et al. (2021).
The following abbreviation is used in this paper: asl = above sea level.
A total of 32 species was found, belonging to nine genera and of the three phytoseiid subfamilies, as subsequently specified.

Male. Unknown.
Holotype: ♀, (accession no. RYTVF-021), Tongtianluo Virgin Forest (678 m asl, 24°59′22″ N, 113°06′51″ E), Ruyuan Yao Autonomous County, Shaoguan City, Guangdong Province, on unknown plant, 14/XI/2021, Fang X.D. coll. Paratype: 2 ♀♀ (accession no. RYTVF-022, RYTVF-023), same locality, host, date and collector as holotype.
The name subcapitatus is derived from a combination of prefix sub and capitatus, indicating that this species is similar to Phytoseius capitatus Ehara, 1966.
By having very similar shape of dorsal shield and vase-shaped ventrianal shield, relative length and thickness of dorsal setae, grandular reticulation on dorsal shield and broad tubular calyx of spermatheca, Phytoseius subcapitatus sp. nov. is very similar to P. capitatus, but the new species differs by having a macroseta on genu, tibia, basitarsus and telotarsus of leg IV, while P. capitatus only has macroseta only on tibia and basitarsus of leg IV. Additionally, the new species has the anterior part of the ventrianal shield striate, while in P. capitatus the ventrianal shield is smooth.

The name ruyuanensis refers to Ruyuan Yao Autonomous County, the type locality.
By having similar shape of dorsal shield, pentagonal and striated ventrianal shield, stronger sclerotization of the calyx near the vesicle, a knobbed macrosetae on genu, tibia and basitarsus of leg IV, Typhlodromus ruyuanensis sp. nov. is most similar to T. orientalis Wu, 1981, T. armiger Ehara & Amano, 1998 and T. chinensis Ehara & Lee, 1971. By having similar shape of dorsal shield, ventrianal shield, calyx of spermatheca and knobbed macrosetae on leg IV, this new species is also similar to T. lobatus Zannou, Moraes & Oliveira, 2008 and T. microbullatus van der Merwe, 1968. Differences between Typhlodromus ruyuanensis sp. nov. and the related species are given in Table 3.
Wu et al. (2009) reported seven species from Ruyuan Yao Autonomous County. In a subsequent study, Fang et al.(2020a) reported other 17 species from the same area. Thus, until now, 24 phytoseiid species had been reported from this county, mainly from Nanling National Nature Reserve. As a result of the present work, 20 other species were added to the known phytoseiid fauna in Ruyuan Yao county, namely N. womersleyi, A. longisaccatus, A. obtuserellus, E. australis, T. ochii, T. syzygii, P. orientalis, P. salebrosus, O. subtropicus, S. jianyangensis, P. crinitus, P. nipponicus, T. agilis, T. insularis, T. serrulatus, T. zhaoi, T. xiufui as well as the three newly described species, Euseius hamiltonii sp. nov., Phytoseius subcapitatus sp. nov. and Typhlodromus ruyuanensis sp. nov. Thus, 44 species are now known from Ruyuan Yao County, belonging to nine genera in the three phytoseiid subfamilies.
Nanling Mountain is one of the richest biodiversity hotspots in China (Pang, 2003), additional surveys are still required to adequately characterize its biodiversity. Amblyseius herbicolus (with 74 specimens collected) and S. okinawanus (with 49 specimens collected) accounted for respectively about 31 and 20% of all specimens collected in this study. These were the dominant species in this survey. But their ecological role is still unknown, which also needs to be revealed in the future.
