Abstract Species of the spider genus Belisana Thorell, 1898 exhibit high diversity in Guizhou, southwestern China. Previously, only eight species of Belisana were recorded in Guizhou. In this study, nine new species are described from karst caves: Belisana bijie Wang, S. Li & Yao, sp. nov., B. /iupanshui Wang, S. Li & Yao, sp. nov., B. majiang Wang, S.

In addition, a list of all species of Belisana from Guizhou is provided. Key words: Biodiversity, cellar spiders, daddy-long-legs, invertebrate, morphology, taxonomy Introduction Belisana Thorell, 1898, the second largest genus in the Pholcidae C.L. Koch, 1850, comprises 160 species (WSC 2024). These species inhabit diverse mi- cro-habitats, e.g., beneath rocks, in caves, on the underside of leaves, among leaf litter, and amidst foliage in the canopy (Huber 2005; Yao et al. 2015; Zhao et al. 2023a). They are primarily distributed in southern China, as well as in the Indo-Malayan and Australasian regions (Huber 2005; Yao and Li 2013; Yao et al. 2018; Zhu et al. 2020; Zhu and Li 2021). Currently, 46% of the species (74 spp.) have been documented from southern China (WSC 2024), of which Yunnan boasts the highest concentration of species, accounting for 42% (31 spp.; Zhang et al. 2024b). Guangxi and Hainan, which have the second and third highest species diversity of Belisana, respectively, have recorded only 11 and ten species. Recently, numerous surveys targeting pholcid spiders have been conducted in China, resulting in the discovery and reporting of a large number of new species (e.g., Yao et al. 2021; Lu et al. 2022; Zhao et al. 2023b; Yang et al. 2024a, b). Nevertheless, these efforts have primarily focused on Phol- cus Walckenaer, 1805, found in epigean environments in northern and central 265 Bing Wang et al.: Nine new species of Belisana spiders, with a list from Guizhou, China China, with relatively few reports on Belisana from hypogean environments in southern China (10 spp.; Wang et al. 2024; Zhang et al. 2024a, b). Guizhou, located in the southwest of China, is renowned for its abundant karst caves. The extreme cave environmental conditions have been regarded as the primary factors of maintaining species endemism within caves (Lefé- bure et al. 2006; Yao et al. 2016). Nevertheless, only eight endemic species of Belisana have been recorded from Guizhou (Chen et al. 2009; Zhang and Peng 2011; Chen et al. 2016; Yang et al. 2023a; Wang et al. 2024). Among these, seven species are collected from caves. This work aims to report the nine new species, a new record found in karst caves (Fig. 1), and to provide an updated list of species of Belisana from Guizhou (Table 1). Materials and methods Specimens were examined and measured with a Leica M205 C stereomicro- scope. Left male palps were photographed. Epigynes were photographed be- fore dissection. Vulvae were photographed after treating them in a 10% warm solution of potassium hydroxide (KOH) to dissolve soft tissues. Images were captured with a Canon EOS 750D wide zoom digital camera (24.2 megapixels) mounted on the stereomicroscope mentioned above and assembled using Hel- icon Focus v. 3.10.3 image stacking software (Khmelik et al. 2005). Drawings were done with Procreate 5.0.2 (Savage Interactive Pty. Ltd.). All measurements are given in millimeters (mm). Leg measurements are shown as: total length (fe- mur, patella, tibia, metatarsus, tarsus). Leg segments were measured on their dorsal sides. The distribution map was generated with ArcGIS v. 10.2 (ESRI Inc.). The specimens studied are preserved in 75% ethanol and deposited in the Institute of Zoology, Chinese Academy of Sciences (IZCAS) in Beijing, China. Table 1.

Including the nine species de- scribed in this paper, there are now 83 species of Belisana in southern China, representing 49% of the global total of the genus. Thailand, Indonesia, and Viet- nam rank second, third, and fourth, respectively, in species diversity of Belisana; however, these countries have recorded only 19, 18, and 17 species, respec- tively. Other countries, such as Laos (8 spp.), Malaysia (8 spp.), and Sri Lanka (6 spp.), have recorded fewer than ten species (WSC 2024). This high level of activity in China contrasts with the sporadic coverage of Southeast Asia, where most research has been conducted by foreign arachnologists, and several countries lack native expertise in this field (Yao and Li 2021; Zhang et al. 2022; Yang et al. 2023b). Given that Southeast Asia encompasses the Indo-Burma and Sundaland biodiversity hotspots, we anticipate that further exploration will reveal additional, as-yet-undiscovered species diversity of Belisana.
