The Alamedin Gorge is one of the famous resorts in Kyrgyzstan. There are more than 150 thousand vacationers and tourists visiting this gorge each year, and the visitors could be potential hosts for ectoparasites. Thus, the risk of epidemic diseases caused by ectoparasites could not be ignored. To monitor the abundance of parasitic arthropods and their hosts is very important for early warning and controlling the epidemic disease accurately. In this paper, rodents were captured with traps and ectoparasitic acarines were separated from them in the Alamedin Gorge in different seasons from 2019 to 2020. It showed that there were 33 species in 15 genera representing six families of ticks, gamasid mites and chigger mites parasitizing on five species of rodents. Neotrombicula (Neotrombicula) kharadovi, N. (N.) monticola and Ixodes crenulatus are dominant species. The species diversity of host rodent and parasitic acarines, the seasonal dynamic of communities of acarines, the distribution of acarines in different biotopes and elevation gradients were analysed. It is helpful for assessing the risk of the epidemic disease, and establish effective preventive measures by sanitary and epidemiological services in this area.

The diversity and biology of the moss and leaf litter-inhabiting flea beetles are still poorly known. In this study, three new species of Benedictus are described from China: Benedictus fuanensis Ruan & Konstantinov, sp. nov., Benedictus quadrimaculatus Ruan & Konstantinov, sp. nov., and Benedictus wangi Ruan & Konstantinov, sp. nov. Comments on their biology are given. Benedictus quadrimaculatus has a highly unusual morphological feature not reported before in flea beetles: black spots on the abdominal tergites that are visible through the elytra. Traditional and modified ethanol traps were tested and proven useful for collecting leaf litter- and moss-inhabiting flea beetles. Based on our tests, eight traps could collect one specimen each day in the testing sites in Fujian Province; three traps could collect one specimen each day in the testing sites in Guangdong Province.

Twelve new troglomorphic pseudoscorpion species of the genus Bisetocreagris Ćurčić, 1983 (Family Neobisiidae) are described based on specimens collected from karst caves in Guizhou Province, China: Bisetocreagris ampla sp. nov. from Hei Cave (Zunyi City), B. aspera sp. nov. from Tu Cave (Tongren City), B. brevis sp. nov. from Yehu Cave (Tongren City), B. changbing sp. nov. from Sanyuan Cave and Guanyin Cave (Zunyi City), B. chumi sp. nov. from Tufei Cave (Zunyi City), B. grandis sp. nov. from Wulibeidadong Cave (Bijie City), B. jiangi sp. nov. from Anjialin Cave (Tongren City), B. longidigitata sp. nov. from Mao’er Cave (Guiding County), B. que sp. nov. from Yanggong Cave (Sandu County), B. sanmen sp. nov. from Sanmen Cave (Zunyi City), B. xishui sp. nov. from Dongkoushan Cave (Zunyi City), B. tenuipalma sp. nov. from Sanjie Cave (Zunyi City). Detailed diagnoses, descriptions, and illustrations are provided for all species.

Matsumuraeses phaseoli is a Lepidopteran pest that primarily feeds on numerous species of cultivated legumes, such as Glycine and Phaseolus. It is widely distributed in northeast Asia. A novel granulovirus, designated as Matsumuraeses phaseoli granulovirus (MaphGV), was isolated from pathogenic M. phaseoli larvae that dwell in rolled leaves of Astragalus membranaceus, a Chinese medicinal herb. In this study, using next-generation sequencing, we report the complete genome of MaphGV. MaphGV genome comprises a double-stranded DNA of 116,875 bp, with 37.18% GC content. It has 128 hypothetical open reading frames (ORFs). Among them, 38 are baculovirus core genes, 18 are lepidopteran baculovirus conserved genes, and 5 are unique to Baculoviridae. MaphGV has one baculovirus repeat ORF (bro) and three inhibitors of apoptosis proteins (iap), including a newfound iap-6. We found two atypical baculoviral homologous regions (hrs) and four direct repeats (drs) in the MaphGV genome. Based on phylogenetic analysis, MaphGV belongs to Clade b of Betabaculovirus and is closely related to Cydia pomonellagranulovirus (CpGV) and Cryptophlebia leucotretagranulovirus (CrleGV). This novel baculovirus discovery and sequencing are invaluable in understanding the evolution of baculovirus and MaphGV may be a potential biocontrol agent against the bean ravaging pest.

Oribatid species from China of the genus Indoribates and Lauritzenia are studied, with description of a new species Indoribates (Indoribates) subiasi sp. nov. based on adult materials collected from China. Indoribates (I.) japonicus (Aoki, 1988), I. (Haplozetes) vindobonensis curtipilis (Kunst, 1977), and Lauritzenia (Incabates) nuda (Hammer, 1961), are recorded in China for the first time. A new combination is proposed: Lauritzenia (Incabates) nobilis (Golosova, 1984) comb. nov. (from the genus Cosmobates Balogh, 1959). Two new synonyms are proposed: Indoribates (Haplozetes) vindobonensis curtipilis (= Haplozetes ulykpani Bayartogtokh & Aoki, 1998 syn. nov.) and Indoribates (Indoribates) Jacot, 1929 (= Indoribates (Bihaplozetes) Subías, 2020 syn. nov.). A key to the known species of Indoribates and Lauritzenia from China is also provided.

The oribatid mite genus Arphthicarus Niedbała, 1994 (Phthiracaridae) is reported in China for the first time. Two new species of Arphthicarus are described: Arphthicarus baculus sp. nov. from Hunan Province, and Arphthicarus spiniformis sp. nov. from Guangxi Province. http://zoobank.org/urn:lsid:zoobank.org:pub:A1729EB7-2C99-4BF6-94EB-229E2A743D84.
