In previous taxonomic studies, identification of Atlanticus species was mainly based on male morphological features, such as cercus, tenth abdominal tergum and subgenital plate. In this study, we systematically revise eight Atlanticus species (61 individuals) in East China. We sequence COI genes of all samples for identification, and compare morphologies and male calling songs. The classification based on male cerci, calling songs, and COI genes is consistent. In contrast, the morphologies of male tenth abdominal tergum and subgenital plate varied among species. In addition, we regard A. jiangyei Liu, Wang & Cheng, 2016 as a junior synonym of A. pieli Tinkham, 1941, and A. helleri Liu, Wang & Cheng, 2016 as a junior synonym of A. kiangsu Ramme, 1939.

To date, only two whip spider species have been recorded in China. We describe a new species, Sarax sinensis sp. nov., from Fujian, China. This species is morphologically similar to S. ioanniticus (Kritscher, 1959), S. israelensis (Miranda et al., 2016), and S. seychellarum (Kraepelin, 1898), but can be distinguished by the combination of the following characters: 35 segments in leg I tarsus, eight teeth on cheliceral claw, and four dorsal and ventral spines respectively on pedipalp femur. To examine the evolutionary history of S. sinensis sp. nov., we sequenced 12S, 16S, and COI gene regions of our specimens and inferred its phylogenetic position. The inferred phylogenetic trees placed the new species within Sarax, with its closest relative being distributed across the western Asia. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).

The genus Parapentacentrus Shiraki, 1930 includes two species with long wings. In this paper, we report one new species, P. brevipennis He sp. nov., from Jinping, Yunnan, China. The new species have short forewings and hindwings, and have differences in the shape of supra-anal plate and male genitalia. DNA Barcode (COI gene) of this new species are provided. The type specimens are deposited in Museum of Biology, East China Normal University (ECNU).

A new species of Tiger Gecko in the genus Goniurosaurus is described from Guangdong, China. This new species, Goniurosaurus wangshu sp. nov. is the fifth species of Goniurosaurus found in karst topography of Guangdong. It is distinguished morphologically from congeners in this region by the combination of thirteen precloacal pores in male; dorsal ground color of head, body, and limbs in adults yellow; and iris orange. To validate our morphological inferences and support the description of Goniurosaurus wangshu sp. nov. as a new species, we sequenced 16S, CMOS, cytb, and RAG1 gene regions and performed molecular phylogenetic analyses. Phylogenetic analysis places the new species within the G. yingdeensis group and highlights the evolutionary distinction between this new species and other described congeners.

There are hundreds of filiform mechanosensory hairs on the cricket cercus, however, such sensory hairs have never been reported on cricket foretiba. In this study, we collected a new species from China, which possesses two long filiform hairs on foretibia. Combined with its burrowing habit, these hairs mainly contribute to detecting ground vibration. We describe a new genus for this new species Fodigryllus bisetus gen. et sp. nov. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).

We provide a key to mute Trigonidiinae species from China, and provide morphological features of some nondescript species in brown color. We established a new genus, Zilingxi He gen. nov. with two new species Z. danmai He sp. nov. and Z. dian He sp. nov. from China. The new genus possesses a black line above clypeus; pseudepiphallic paramere of male genitalia possessing 2–3 branches; ovipositor shorter than other genera. Two new species are very similar in morphology, but different in the color pattern in frontal rostrum, and the shape of male genitalia. The type specimens are deposited in Museum of Biology, East China Normal University (ECNU).

Phonarellus Gorochov, 1983 is comprised of 11 extant species. We describe a new species, Phonarellus (Phonarellus) zebripes He sp. nov. from Yunnan province, China. It is different from other Phonarellus species in possessing black and white stripes on the hind femora. The type specimens are deposited in Museum of Biology, East China Normal University (ECNU).

To date, only one species of whip spider has been recorded in China. Here, we describe a new species, Weygoldtia hainanensis sp. nov., from Hainan, China. The new species is morphologically similar to W. davidovi (Fage, 1946) and W. consonensis Miranda et al. 2021, but can be distinguished with a combination of the following characters: 26 segments in tibia I, 6-7 teeth on chelicerae, distitibia IV trichobothria sc and sf series each with 10-11 trichobothria. To validate our morphological inferences and support the erection of W. hainanensis sp. nov. as a new species, we sequenced the COI gene region for two individuals and performed molecular phylogenetic analyses. The inferred phylogenetic trees placed the new species within Weygoldtia and highlighted the evolutionary distinction between W. hainanensis sp. nov. and currently described whip spiders. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).

In this paper, one new genus, Ptosoproctus gen. nov., is established with two new species: P. lanzhouensis sp. nov. and P. baishishanicus sp. nov., described and illustrated based on material collected from northern China. The genus Eulithoxenus Bey-Bienko, 1951 is recorded from China for the first time. E. emeljanovi Mishchenko, 1968 is redescribed. Supplemental description of Uvarovina chinensis Ramme, 1939 is provided. COI and ND2 genes of the three Chinese Drymadusini genera mentioned above were used to reconstruct the phylogenetic tree. Molecular result support the validation of the new genus.

We studied the relationship of the genera Loxoblemmus Saussure, 1877 and Asonicogryllus He, 2019 by reconstructing the phylogenetic tree based on 2 mitochondrial genes and 2 ribosomal genes. The result shows that Loxoblemmus is paraphyletic. Thus, we place Asonicogryllus as a subgenus of Loxoblemmus. Meanwhile, we report a new species of Asonicogryllus, L. (A.) bronzus He sp. nov. The new species is similar to L. (A.) kwanghua, but it has well developed forewings and hindwings. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).

A new species, Schizodactylus jimo He sp. nov., is described from Yunnan, China. The Schizodactylidae is recorded from China for the first time. The new species is similar to S. salweenensis, but different based on the shape of epiproct and other characters. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).

Six species of geckos in the genus Goniurosaurus have been recorded from Guangxi, China. Here we describe a new species, Goniurosaurus chengzheng sp. nov. The new species is similar to allied species from Guangxi, but unique in a combination of the following characters: (1) four body bands with three between limb insertions; (2) precloacal pores 20; (3) body color reddish- brown; (4) snout to eye distance: eye to ear distance < 1. We used the mitochondrial genes 16S and cytb to confirm the distinctiveness of the species and place it within a molecular phylogeny of Goniurosaurus. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).

Parapteronemobius contains 7 species or subspecies distributed in East Asia with only one species recorded from China. In this study, we reported the second species, P. chenggong He sp. nov., from Zhejiang. The new species differs from P. dibrachiatus in body size, male genitalia and COI gene. The phylogeny of this genus in subfamily Nemobiinae are discussed based on COI, 18S and 28S genes. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).

We reported a new genus Majialandrevus from Western Yunnan, China. The new genus differs from other genera in having the following combination of characters: short forewings, male genitalia with blunt distal parts of posterolateral epiphallic lobes, absence of medial lobes of epiphallus and ectoparamere being membranous. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).

The effectiveness of China’s stock market is low, and the degree of information disclosure is worse than that of capital markets in developed countries. In particular, GEM stocks are slow to reflect basic supply and demand factors, and investor sentiment will have an impact on GEM stock prices. This paper selects the historical posting data of “GEM Finger Bar” of Eastmoney website. Firstly, Bayesian model algorithm is used to classify the sentiment of text comments, and investor sentiment proxy variables are constructed. Then, through correlation analysis and Granger causality test, the relationship between investor sentiment and the GEM stock price in China is empirically studied. The results show that there is a strong correlation between GEM stock prices and investor sentiment.
