Abstract

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 Yin et al., 2012.

Introduction

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 (Zhao et al. 2022), and China’s mountainous landscape has provided refuge for organisms, enabling species such as spiders to survive glacial periods (Yao et al. 2021; Lu et al. 2022). Approximately 5700 spider species from 69 families have been recorded from China (Biodiversity Committee of Chinese Academy of Sciences 2022). The southwest (Himalayan and Hengduan mountains, and Yunnan-Guizhou Plateau), has been the center of diversification for several spider groups (Li 2020) and has become a biodiversity hotspot for researchers. Many spider species are discovered from there in the last 15 years (Li and Lin 2016; Li 2020). In contrast to these areas, species richness of spiders in non-hotspots, such as Jiangxi Province, has not been given enough attention. Recently, in Jiangxi, which has a mountain terrain, many spider taxa have been discovered, such as Agelenidae (Liu et al. 2020a, 2021a), Dictynidae (Liu et al. 2018), Oonopidae (Liu et al. 2016, 2019), Phrurolithidae (Liu et al. 2020b, 2020c, 2021b, 2022a), Salticidae (Liu et al. 2017b, 2022c), Thomisidae (Liu et al. 2017a, 2022b), and Gnaphosidae (this study). These discoveries lend support to mountainous landscapes being refuges for spiders during glacial periods.

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 (Li and Lin 2016; Li 2020). Although Gnaphosidae is the ninth largest family in China, the number of taxonomic papers dealing with this family in the last decade is few (WSC 2022). Among species of ground spiders recorded from China, more than 60% are recorded from northern China, namely from Qinghai, Xinjiang, Neimenggu, Hebei, Gansu, Beijing, Shanxi, Liaoning, Xizang, and Henan provinces. The family is poorly studied in Jiangxi Province located in southern China, and only four species of Gnaphosidae are recorded from this province: Allozelotes lushan Yin & Peng, 1998, Gnaphosa kompirensis Bösenberg & Strand, 1906, Hitobia yasunosukei Kamura, 1992, and Zelotes liaoi Platnick & Song, 1986 (Li and Lin 2016).

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.

Materials and methods

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 Platnick and Shadab (1982) and Fomichev and Marusik (2021). Leg measurements are given as total length (femur, patella, tibia, metatarsus, tarsus).

The abbreviations used in the text are as 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.

Haplodrassus Chamberlin, 1922

Comments

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 Omelko and Marusik (2012), i.e., the caspius, dalmatensis, kulczynskii, mediterraneus, montanus, signifier, silvestris, tegulatus, and umbratilis groups. To date, only 13 species of Haplodrassus are recorded from China. Except for Haplodrassus guiyangensis Yan & Yu, 2021, the others were recorded more than 10 years ago.

Haplodrassus montanus Yin et al., 2012: 1177, fig. 627a–f (♂♀).

Material examined

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.

Etymology

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.

Diagnosis

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. Figs 1D, 2A, B vs Omelko and Marusik 2012: figs 7, 10). In addition, H. yinae sp. nov. possess 5 or 6 ridges on the embolic base (vs 6–8 ridges in H. guiyangensis; 7 or 8 ridges in H. hatsushibai; 6 or 7 ridges in H. huarong; 3 or 4 ridges in H. montanus) (cf. Fig. 1C, D vs Yan et al. 2021: figs 1A, C, 2A, B and Omelko and Marusik 2012: figs 7, 8, 10, 11) and has a small tooth-like basal process (BP) directed at 9 o’clock in ventral view (vs 11 o’clock in H. guiyangensis; a large laminar, tooth-like basal process, directed at 11 o’clock position in H. hatsushibai, H. huarong and H. montanus) (cf. Figs 1D, 2A, B vs Yan et al. 2021: figs 1C, 2B and Omelko and Marusik 2012: figs 7, 10 and Yin et al. 2012: fig. 625f, g). The female of the new species resembles those of H. montanus in having pair of posterior pockets (PP) located in posterolateral part of the atrium, but it can be distinguished by the septum (Se) narrowing posteriorly (vs septum narrowing anteriorly) (cf. Fig. 3C vs Omelko and Marusik 2012: fig. 20). Also, it can be separated from H. hatsushibai by posterior pockets located in posterolateral part of the atrium (vs posterior pockets located in posteromedial part of the atrium) (cf. Fig. 3C vs Omelko and Marusik 2012: fig. 23) and from H. huarong by the copulatory ducts (CD) as wide as spermathecae (Sp) (vs 1/3 of spermathecal width) (cf. Fig. 3D and Yin et al. 2012: fig. 625e).

Cymbium 2.5× longer than wide. Tegulum simple and smooth, tapers anteriorly. Conductor (Co) membranous. Sperm duct (SD) U-shaped. Embolus longer than conductor (Em), cone-shaped and twisted.

Female. Unknown.

Comments

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.

Distribution

Known only from the type locality, Jiangxi Province, China (Fig. 9).

Liu et al. leg.

Etymology

The specific name derived from the county where the type locality is located and is a noun in apposition.

Diagnosis

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 6C–F, 7 vs Song et al. 2004: fig. 158C, D). The female of Z. dingnan can be distinguished from that of Z. liaoi by the teardrop posterior part of the fovea (Fo) (vs subtriangular) and by the copulatory ducts (CD) divided into three parts (anterior, medial, and posterior) (vs two) (Figs 8C, D vs Song et al. 2004: fig. 158A, B).

Copulatory ducts (CD) consist of three parts: longitudinal anterior part, C-shaped median part, which is 2× wider than anterior, and swollen posterior part. Lateral glands (LG) twice shorter than median part of copulatory ducts, directed laterally. Spermathecae (Sp) oval, connected with copulatory ducts by a short bending tube. Fertilisation ducts (FD) slightly curved.

Comments

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.

Distribution

Known only from the type locality, Jiangxi Province, China (Fig. 9).
