A list of 26 gnaphosid species belonging to 14 genera collected in Jiangxi Province, China, is provided. Three new species of ground spiders from Jiangxi Province of China are diagnosed, described, and illustrated: Haplodrassus yinae Liu, sp. nov. (♂♀), Hitobia xiaoxi Liu, sp. nov. (♂), and Zelotes dingnan Liu, sp. nov. (♂♀). Haplodrassus yinae Liu, sp. nov. was previously erroneously recorded in Jiangxi Province as H. montanus
Asia, biodiversity, distribution, gnaphosid spiders, new species, taxonomy
The rich biodiversity of China is likely due to two reasons: cenozoic tectonic evolution in the Tethyan, has greatly changed the landforms and environment of Eurasia and driven the evolution of animals (
Gnaphosidae Banks, 1892, commonly known as ground spiders, is the sixth largest spider family with a global distribution, comprising 2414 extant species belonging to 144 genera (WSC 2022). Currently, 213 species belonging to 36 genera are known from China (
While studying ground spiders from Jiangxi Province, we came across several undescribed and poorly known species, as well as many described species. The aims of the present paper are to provide detailed descriptions of three new species and to report findings of 26 species belonging to 14 genera.
Specimens were examined using a Zeiss Stereo Discovery V12 stereomicroscope with a Zoom Microscope System. Both male palps and female copulatory organs were detached and examined in 80% ethanol, using a Zeiss Axio Scope A1 compound microscope with a KUY NICE CCD. The epigynes were cleared in trypsin enzyme solution to dissolve soft tissues. For SEM photographs, specimens were dried under natural conditions, sprayed with gold with a small ion-sputtering apparatus ETD-2000, or left without coating, and photographed with a ZEISS EVO LS15 scanning electron microscope. Specimens, including detached male palps and epigynes, were stored in 75% ethanol after examination. All the specimens are deposited in Animal Specimen Museum, Life Science of College, Jinggangshan University (ASM-JGSU).
Measurements were taken with the AxioVision software (SE64 rel. 4.8.3) and given in millimetres. Terminology of the male and female copulatory organs follows
Eyes: ALE, anterior lateral eye; AME, anterior median eye; MOA, median ocular area; PLE, posterior lateral eye; PME, posterior median eye.
Leg segments: Fe, femur; Mt, metatarsus;Pt, patella; Ta, tarsus; Ti, tibia.
Spination: d, dorsal; p, prolateral; r, retrolateral; v, ventral.
Male palp: BP, basal process; Co, conductor; EA, embolic apophysis; Em, embolus; EP, embolic projection; IS, intercalary sclerite; LaP, lamellar process; MA, median apophysis; RTA, retrolateral tibial apophysis; SD, sperm duct; StP, subterminal process; TA, terminal apophysis; TP, terminal process; UP, upper process.
Epigyne: AP, anterior pocket; CD, copulatory duct; CO, copulatory opening; FD, fertilization ducts; Fo, fovea; H, hood; LG, lateral gland; MP, median pocket; PP, posterior pocket; Se, septum; Sp, spermatheca.
The known gnaphosid spider fauna of Jiangxi Province is complemented by 23 additional species belonging to 13 genera and now numbers 27 species in 14 genera. The full list of gnaphosid spiders recorded in this province is presented in Table

This genus includes 83 species, mainly distributed in the Palaearctic (WSC 2022). A smaller number of species are known from the Nearctic and Oriental realms (WSC 2022). The genus was divided into nine species groups, based on morphological characteristics, by
Haplodrassus montanus
Holotype ♂, China: Jiangxi Province, Ji’an City, Jinggangshan County Level City, Jinggang Mountain National Nature Reserve, Dongshang Town, Jiangshan Village, 26°46'01.56"N, 113°54'53.65"E, 326 m, 4.II.2021, K. Liu et al. leg. Paratypes: 2 ♂, 1 ♀, the same data as the holotype.
The specific name is a matronym in honour of Prof. Changmin Yin, the first to find and recognise this species, in honour of her great contribution to Chinese arachnology; noun (name) in genitive case.
The new species belongs to the montanus group. The male of the new species is similar to H. guiyangensis Yan & Yu, 2021, H. hatsushibai Kamura, 2007, H. huarong Yin & Bao, 2012, and H. montanus Paik & Sohn, 1984 in having an oval tegulum, a bifurcate embolic apophysis (EA), and a hook-shaped median apophysis (MA), but it can be differentiated from H. hatsushibai and H. montanus by the absence of the basal tooth on the embolus (cf.

The genus includes 21 species, all of which are distributed in south, south-east, or east Asia (China, Thailand, Korea, Japan, Vietnam, India) (WSC 2022). More than two-thirds of all known species have been described and/or reported from China.
Holotype : ♂, China: Jiangxi Province, Ji’an City, Jinggangshan County Level City, Jinggang Mountain National Nature Reserve, Huangao Town, Fuxi Village, Xiaoxi Forest Farm, 26°28'22.92"N, 114°11'53.07"E, 413 m, 14.XI.2020, Liu et al. leg.
The specific name derived from the type locality is a noun in apposition.
The male of this new species is similar to Hitobia shaohai Yin & Bao, 2012 and H. taiwanica Zhang, Zhu & Tso, 2009 in having a short RTA and retrolaterally oriented embolus (Em), but it differs from them in the subtriangular RTA (vs beak-like in H. shaohai and H. taiwanica) and the embolus with twisted apex (vs twisted apex absent in H. shaohai and H. taiwanica) (cf. Figs

Female. Unknown.
The new species together with H. shaohai and H. taiwanica clearly belongs to the same group based on configuration of their male palps. Unfortunately, only one male of H. xiaoxi sp. nov. was found and several Hitobia species from southern China are known only from females: H. chayuensis Song, Zhu & Zhang, 2004, H. shimen Yin & Bao, 2012, and H. yunnan Song, Zhu & Zhang, 2004. Thus, H. xiaoxi sp. nov. may be a junior synonym of any of the above-mentioned species. However, it should be noted that the new species differs from all females by the abdominal pattern of a broad arc-shaped white stripe subposteriorly (vs wavy wite stripe in H. yunnan, thin transverse white stripe in H. chayuensis, and herringbone-pattern in H. shimen). For this reason, we consider H. xiaoxi sp. nov. as a separate species. This hypothesis will be confirmed or rejected in the future when both sexes of the new species are collected together.
Known only from the type locality, Jiangxi Province, China (Fig.
With 397 described species and worldwide distribution, Zelotes is the most speciose genus of the family (WSC 2022).
Holotype : ♂, China: Jiangxi Province, Ganzhou City, Dingnan County, Lingbei Town, Aonao Village, near 42# poles, 25°01'48.95"N, 115°06'11.01"E, 395 m, 5.X.2020, K. Liu et al. leg. Paratype: 1 ♂: Dayu County, Neiliang Town, Tianhua Mountain, 25°25'38.09"N, 114°01'43.95"E, 1019 m, 3.X.2020, other data same as holotype; 1 ♂: near the county boundary between Xunwu and Anyuan Counties, Guizhumao parking lot, 24°55'35.36"N, 115°27'25.09"E, 716 m, 7.X.2020, other data same as holotype; 1 ♀: Anyuan county, Sanbaishan National Forest Park, hiking trails, 25°00'28.19"N, 115°25'59.45"E, 511 m, other data as same as previous; 1 ♂: Ji’an City, Jinggangshan Level City, Dongshang Town, Jiangshan Village, Qilichuan, 26°46'88.81"N, 113°52'00.83"E, 665 m, 4.II.2021, K. Liu et al. leg.
The specific name derived from the county where the type locality is located and is a noun in apposition.
The male of this new species is similar to Zelotes liaoi Platnick & Song, 1986 in having a finger-like RTA, U-shaped sperm duct (SD), a triangular median apophysis (MA) in ventral view and a strong terminal apophysis (TA) with a spine-like apex, but differs by the clearly visible embolic projection (EP) (vs invisible or absent) and by the embolus (Em) with a membranous apex bending toward posterior part of tegulum (vs sclerotized apex bending toward anterior part of tegulum) (Figs

The holotype male and the paratype female were collected in different localities. Distance between Guizhumao parking lot and Sanbaishan National Forest Park is about 12 km, which is very close. Moreover, both specimens have similar habitus and coloration. For these reasons, we consider them as conspecific. This hypothesis will be confirmed or rejected in future when both sexes are collected together.
