摘要: This study provides detailed descriptions and illustrations of a new species, Psilota nigritarsa Huo & Zhao, sp. nov., and a newly recorded species in China, P. nigripilosa Shiraki,1968. It also offers additional measurements for Psilota bashanensis Huo, Zhao & Liu, 2022.The paper proposes a reclassification of the P. innupta-group in the Palaearctic Region into two subgroups based on the morphology of the male genitalia. An updated taxonomic key for the species of the P. innupta-group within the Palaearctic Region is also provided.

摘要: In the Homoneura (Homoneura) picta group, H.(H.) dahanshanensis Liu&Shi, sp.nov. is described as new to science and H.(H.) picta (de Meijere, 1904) is supplemented with detailed descriptions of significant intraspecific variations in abdominal striping patterns and structures of the syntergosternite and hypandrial apodeme. Photographic illustrations of these variations are also provided. A key to the 7 species of the group in China is presented.

摘要: Four cynipid gall wasps belonging to three genera are reported with descriptions of their host plants and galls, i.e., Belizinella vicina Kovalev, 1965, Cerroneuroterus folimargo(Monzen, 1954), C. monseni(Dettmer, 1934) and Neuroterus hakonensis Ashmead, 1904. The genus Belizinella and three species, B. vicina, C. monseni and N. hakonensis, are recorded in China for the first time. The species B. vicina is redescribed for the missing or incongruent features from its original description. In addition, the gall host for Ufo rufiventris Wang, Guo,Wang, Pujade-Villar & Chen is also recorded here for the first time.

摘要: Dentisphaera Páll-Gergely & Jochum, 2017 is a troglobitic land snails genus known to harbour only one species found in a single cave in North Vietnam. Based on recently collected specimens from China, three species, Dentisphaera lagredeae Chen, Grego & Páll-Gergely, sp.nov., Dentisphaera shzha Chen, Grego & Páll-Gergely, sp. nov. and Dentisphaera zhoui Chen,Lin & Páll-Gergely, sp. nov. are introduced as new to science. The distribution range of Dentisphaera is extended based on the collecting records of these new species.

摘要: Based on available records, a comprehensive overview of the biodiversity and geographical distribution of Collembola in China is presented. A total of 735 species, 155 genera and 20 families were recorded in the checklist, including current name information, synonyms, geographical records, and bibliographic references. Taxonomic notes were added where necessary and Chinese translations were provided for genera and families. The following new combinations are proposed: Rambutsinella grinnellia(Wang, Chen & Christiansen, 2004) comb. nov. for Pseudosinella grinnellia Wang, Chen & Christiansen 2004; Rambutsinella hui(Wang, Chen & Christiansen, 2003) comb. nov. for Pseudosinella hui Wang, Chen & Christiansen 2003; and Rambutsinella tridentifera(Rusek, 1971) comb. nov. for Pseudosinella tridentifera Rusek 1971. In addition, certain species have been merged with their synonyms. This checklist includes articles published up to August 2023.
