“…Three additional subterranean-adapted species occurred in multiple caves with maximum distances ranging from 81.27 and 137.6 km (Table 3). As many troglomorphic arthropods are identified as short-range endemic species, occurring in a single cave or geological formation (Reddell 1994, Culver et al 2000, Christman et al 2005, Deharveng et al 2008, Tian 2011, Harvey and Wynne 2014, Gao et al 2018, Nitzu et al 2018 and that rivers and valleys/ lowland areas often result in vicariance (Barr 1985, Faille et al 2015, Katz et al 2018, the genetic relatedness of at least these three species should be further examined using genetic techniques. While these species may be morphological similar, we suggest they may be genetically distinct -potentially representing different subspecies or lineages.…”

“…This paper revealed that at least 38 troglomorphic millipede species occur in Guangxi. Other examples of SCK's high cave diversity includes at least 19 species of troglomorphic pseudoscorpions (Gao et al 2018), 29 vascular plant species believed restricted to cave entrances (Monro et al 2018), and the richest globally diversity of cavefishes with at least 154 species and nearly half of these species considered single cave endemics (Zhao et al in press). As this work continues, we anticipate the number of subterranean-adapted millipedes, as well as other arthropod species will increase.…”

“…At least 100 troglomorphic (subterranean-adapted) arthropods have been identified from Guangxi (Wynne, unpublished data). Most have been identified as short-range endemic species (Tian 2011, Deharveng et al 2008 with more than half (or 58 species) considered single cave endemics (Gao et al 2018).…”

We synthesized the current knowledge of cave-dwelling millipede diversity from Guangxi Zhuang Autonomous Region (Guangxi), South China Karst, China and described six new millipede species from four caves from the Guilin area, northeastern Guangxi. Fifty-two cave-dwelling millipedes are known for the region consisting of 38 troglobionts and 14 troglophiles. Of the troglobionts, 24 are presently considered single-cave endemics. New species described here include Hyleoglomerisrukouqusp. nov. and Hyleoglomerisxuxiakeisp. nov. (Family Glomeridae), Hylomusyuanisp. nov. (Family Paradoxosomatidae), Eutrichodesmusjianjiasp. nov. (Family Haplodesmidae), Trichopeltisliangfengdongsp. nov. (Family Cryptodesmidae), and Glyphiulusmaocunsp. nov. (Family Cambalopsidae). Our work also resulted in range expansions of Pacidesmustrifidus Golovatch & Geoffroy, 2014, Blingulussinicus Zhang & Li, 1981 and Glyphiulusmelanoporus Mauriès & Nguyen Duy-Jacquemin, 1997. As with many hypogean animals in Southeast Asia, intensive human activities threaten the persistence of both cave habitats and species. We provide both assessments on the newly described species’ distributions and recommendations for future research and conservation efforts.

“…Since 2017, 39 new subterranean-adapted species across several taxonomic arthropod groups have been described (Gao et al 2017;Huang et al 2017;Li and Wang 2017;Song et al 2017;Tian et al 2017Tian et al , 2018Deuve and Tian 2018;Li et al 2019a). Overall, at least 382 cave-dwelling arthropod species are now known from this region (Ran and Yang 2015;Tian et al 2016;Li and Wang 2017;Gao et al 2018;Feng et al 2019;Li et al 2019b;Liu and Wynne 2019). Incidentally, this work has also resulted in the identification of at least 21 troglomorphic pseudoscorpion species (refer to Feng et al 2019;Li et al 2019b).…”

Subterranean Biology 34: 61-98. AbstractWe summarize and discuss the 29 known cave-dwelling pseudoscorpion species from China. Four new troglomorphic pseudoscorpion species, Parobisium motianense sp. nov., P. qiangzhuang sp. nov., P. sanlouense sp. nov., and P. tiani sp. nov., belonging to the family Neobisiidae, are described based on specimens collected in karst caves in Guizhou, China. Detailed diagnosis, descriptions, and illustrations are presented. We also provide recommendations for management of caves where they occur, as well as the cave arthropod communities and the habitats that support them.

Towards evidence‐based conservation of subterranean ecosystems

Subterranean ecosystems are among the most widespread environments on Earth, yet we still have poor knowledge of their biodiversity. To raise awareness of subterranean ecosystems, the essential services they provide, and their unique conservation challenges, 2021 and 2022 were designated International Years of Caves and Karst. As these ecosystems have traditionally been overlooked in global conservation agendas and multilateral agreements, a quantitative assessment of solution-based approaches to safeguard subterranean biota and associated habitats is timely. This assessment allows researchers and practitioners to understand the progress made and research needs in subterranean ecology and management. We conducted a systematic review of peer-reviewed and grey literature focused on subterranean ecosystems globally (terrestrial, freshwater, and saltwater systems), to quantify the available evidence-base for the effectiveness of conservation interventions. We selected 708 publications from the years 1964 to 2021 that discussed, recommended, or implemented 1,954 conservation interventions in subterranean ecosystems. We noted a steep increase in the number of studies from the 2000s while, surprisingly, the proportion of studies quantifying the impact of conservation interventions has steadily and significantly decreased in recent years. The effectiveness of 31% of conservation interventions has been tested statistically. We further highlight that 64% of the reported research occurred in the Palearctic and Nearctic biogeographic regions. Assessments of the effectiveness of conservation interventions were heavily biased towards indirect measures (monitoring and risk assessment), a limited sample of organisms (mostly arthropods and bats), and more accessible systems (terrestrial caves). Our results indicate that most conservation science in the field of subterranean biology does not apply a rigorous quantitative approach, resulting in sparse evidence for the effectiveness of interventions. This raises the important question of how to make conservation efforts more feasible to implement, cost-effective, and long-lasting. Although there is no single remedy, we propose a suite of potential solutions to focus our efforts better towards increasing statistical testing and stress the importance of standardising study reporting to facilitate metaanalytical exercises. We also provide a database summarising the available literature, which will help to build quantitative knowledge about interventions likely to yield the greatest impacts depending upon the subterranean species and habitats of interest. We view this as a starting point to shift away from the widespread tendency of recommending conservation interventions based on anecdotal and expert-based information rather than scientific evidence, without quantitatively testing their effectiveness.
