Clubiona Latreille, 1804 comprises 503 species across the world, of which 122 species were reported from China. Nearly one-third of Chinese species have been described with single-sex (World Spider Catalog, 2018). Twenty-eight species have been reported from Guizhou Province (Wang et al. 2015; Wu et al. 2015; Li & Lin 2016; Yu et al. 2017; Wang et al. 2018; Zhang et al. 2018).

Limestone areas of China host remarkable radiations of cave animals. The subterranean trechine beetles (Carabidae: Trechini), the most diverse and modified group of subterranean beetles in the world, are extremely diverse in southern China. The first aphaenopsian trechine beetle, Sinaphaenops mirabilissimus Uéno & Wang, 1991 was reported from a limestone cave in Guizhou province. Up to now, 146 species within 48 genera of aphaenopsian trechine have been described in China after almost three decades. Among them, the genera Giraffaphaenops, Xuedytes, Dongodytes, Sinaphaenops and Pilosaphaenops from northwest Guangxi and south Guizhou are the most modified troglobitic trechine beetles known so far in the world. They are remarkable by their morphology combining extremely slender body and elongated appendages. Some of them are diversified or quite widespread, which is not the case of Xuedytes Tian & Huang, 2017, a remarkable monospecific genus known from a single locality so far. In addition to the surveys and collection of specimens, an integrative approach combining the study of systematics, phylogeny, diversification and biogeography patterns of the cave trechine beetles in China is on the way, in order to understand the origin of the remarkable biodiversity and evolutionary success of this group.

Local residents of buffer zones, as a key factor in the World Heritage conservation and sustainable development, have not received sufficient attention in most developing countries, especially in the mountainous areas where poor and backward ethnic minorities live. To fill this research gap, this paper takes the Karst World Heritage buffer zone in Libo, Guizhou Province, southwest mountainous area of China, as the research area, and explores the factors that influence the perception of residents’ responsibility for the World Heritage conservation by taking local residents who are involved in tourism management as the research subjects. Data were collected in the buffer zone of the Libo World Heritage site and 186 valid data were generated. SPSS 25.0 and AMOS 27.0 software were used to analyze the questionnaire data and construct a structural equation model. The results showed that environmental protection behavior had the greatest impact on residents’ perception of responsibility for heritage conservation (0.93), followed by the recognition of heritage value (0.55), tourism positive impact (0.39), and place identification (0.34), among which the positive impact of tourism had a greater impact on the perception of heritage value (0.52). The results of the study emphasize the importance of the recognition of heritage value and positive tourism influence on the formation of residents’ perception of responsibility for heritage conservation, and provide an empirical basis for the conservation of the World Natural Heritage.

Oolitic Hematite Ore

Oolitic hematite is considered to be one of the most refractory ores in the world due to its ultra fine disseminated grain size and complex mineral composition. Various magnetic separation methods were conducted on the oolitic hematite ore samples from Guizhou Province. Because the TFe grades of each size fraction of the grinding products were different from each other, the beneficiation process of “classification – low intensity magnetic separation – high intensity magnetic separation” was finally adopted to guarantee the quality of iron concentrates. After the determined magnetic separation, the relatively good technical indexes are obtained. The TFe grade of iron concentrates is increased from 38.7% to 46.1%, and the iron recovery is 81.7%.

China is now building the largest single dish radio telescope in the world in Guizhou province, which is called Five-hundred meter Aperture Spherical radio Telescope (FAST). A Stewart platform is introduced in FAST as an accuracy adjustable mechanism for feed receivers. The main purpose of this paper is to discuss dimension optimization design method of the Stewart platform based on three optimization objective functions. The optimization objective functions can reflect the operability and accuracy of the Stewart platform, and optimization design flow is presented according to the important degree of the three optimization objectives. Finally, a set of optimized parameters is obtained, and the study in this paper provides a basis for the coming optimization the feed support system for FAST in the next step.

Unknown Male

Three species of Micaria Westring, 1851 are known to occur in the Afrotropical Region, two from Namibia and one from South Africa. All three species are known from a single sex only, either from the male (M. tersissima Simon, 1910) or from the females in the case of M. beaufortia (Tucker, 1923) and M. chrysis (Simon, 1910). In this paper, we redescribe the female of M. beaufortia and describe the previously unknown male of this species. This species has pseudosegmented tarsi and complex scopula formed by two paired rows of setae; these characters are unknown in other Micaria. The setae covering the legs in M. beaufortia are briefly described and the scopula is compared with that of M. fulgens (Walckenaer, 1802). A paired mating plug, previously unknown in Micaria, is documented in M. beaufortia. It was found that M. chrysis and M. tersissima, considered in the World Spider Catalog (2017) as endemics of Namibia, were actually described from Northern Cape Province, South Africa. The taxonomic position of these two species is briefly commented on and distribution records of all three species are mapped.

<p>Conversion therapies have been classified as inhuman treatment or torture on several instances, including by the UN Special rapporteur on torture and other cruel, inhuman or degrading treatment or punishment, and are explicitly prohibited by several professional bodies around the world such as the World Medical Association and the World Professional Association for Transgender Health. They have been defined as “any treatment, practice or sustained effort that aims to change, repress and, or eliminate a person’s sexual orientation, gender identity and, or gender expression” (Malta, 2016).</p><p>However, based on its functional definition, the concept of “conversion therapy” can be successfully used as a broader analytical framework to describe carceral practices that regulate gender identity and expression and, in particular, those implemented by sex-segregated detention facilities.</p><p>This paper argues that, coupled with often restrictive and sometimes impossible means for accessing legal gender recognition to change one’s identity documents, single-sex detention acts as a form of conversion therapy for trans and gender diverse people at least in two ways by coercing detainees into adopting gender expression modes that do not align with their gender identity. In that sense, it can be said that sex-segregated detention acts to change the gender identity or expression of gender diverse detainees and, therefore, can amount to inhuman treatment or torture.</p>

Members of the scale insect family Ortheziidae (Hemiptera: Sternorrhyncha: Coccomorpha) occur all over the world but these small, delicate insects are difficult to find. The largest genus in the Ortheziidae is Newsteadia Green. Previous studies have recorded four species of Newsteadia in China. This study describes and illustrates the adult female, male, prepupal male, and first-, second- and third-instar nymphs of a fifth species, Newsteadia fanjingensis sp. n., from Guizhou Province, China, collected above 2000 m altitude under thick moss on the bark of Acer sp. Identification keys are provided to the adult females of Newsteadia species known in China, and the adult males known worldwide.

We describe Scolopocryptops longipes sp. nov., a new troglobitic scolopocryptopine centipede species from a karstic area in southern China. The species was found in Shuiba Cave of Libo County, Guizhou Province. The cephalic plate wider than long, with complete margination along the lateral margin of cephalic plate; TT6–19 with complete paramedian sutures; tibia, tarsus 1 and tarsus 2 of leg 22 each with one spur; prefemur and femur of ultimate legs glabrous, tibia and tarsi with dense bristles. S. longipes is the second troglobitic scolopocryptopine in China and the fourth in the world described thus far.
