摘要: A monogenean was discovered parasitizing the bladder of Hylarana maosonensis, an amphibian species that was not previously recorded in Yunnan Province, China. Through numerical taxonomy and comparative analysis, the monogenean was identified as a previously undescribed species of the genus Diplorchis within the family Polystomatidae and was named as Diplorchis yunnanensis Fan & Meng, sp. nov. Detail descriptions and illustrations are provided. The typical materials are deposited in the School of Life Sciences at Yunnan Normal University.

摘要: The taxonomic status of Episoriculus umbrinus has been contentious. This study aims to clarify its taxonomic position through mitochondrial genome analysis. Specimens of E. umbrinus were obtained from Liupanshui City, Guizhou Province, China. Genomic DNA was extracted, and 15 primer pairs were designed to amplify and sequence the complete mitochondrial genome of E. umbrinus. The results revealed that the mitochondrial genome of E. umbrinus is a circular double-stranded structure with a length of 17,073 bp, comprising 13 protein-coding genes, 1 control region, 22 tRNA genes, 2 rRNA genes, and 1 origin of L-strand replication. Compared with E. caudatus, differences were observed between the two species in terms of replication origins, gene overlap regions, base lengths, and termination codons. Genetic distance analysis of mitochondrial protein-coding genes showed that the genetic distance between E. umbrinus and E. caudatus ranged from 0.069 to 0.125. A phylogenetic tree constructed based on the concatenated sequences of the 13 protein-coding genes indicated that E. umbrinus clustered as a distinct branch with the other three species within the genus Episoriculus. This study confirmed at the molecular level that E. umbrinus is an independent species rather than a subspecies of E. caudatus. The mitochondrial genome sequence of E. umbrinus provides an important supplementary information for the genetic research of this species and offers new evidence for the phylogenetic study of the tribe Nectogalini.

摘要: The amber sites from the Chiapas Highlands in southwestern Mexico constitute an Oligo-Miocene Amber-Lagerst?tte(ca. 24 Ma) whose mines and pits at Simojovel, Totolapa, and Estrella de Belén yield exceptionally preserved fossil inclusions, notably insects from an estuarine wetland. A comprehensive cross-referenced catalog of insects and their close relatives(Arthropoda: Hexapoda) recorded in Mexican amber has been compiled. The catalog comprises 589 fossil records, including 21 orders, 180 families, 230 genera, and 193 species. Data show the fossil diversity of insects based on 65 years of taxonomic descriptions. The catalog also consists of an online database for consultation and permanent updating. Accordingly, the taxonomic composition of Hexapoda in Oligo-Miocene Mexican amber is a significant addition to the current knowledge of the diversity of Lagerst?tte taxa distributed worldwide.

摘要: The subgenus Dendrotipula was distributed in Palaearctic Region. Only eight species of the subgenus Dendrotipula Savchenko, 1964 were known to occur worldwide, two species were described in China. Based on new collections, we described one new species from Southwest China, Tipula(Dendrotipula) dorsigera Q.C. Yang, sp. nov. A key to the species of Tipula(Dendrotipula) from world is presented.

摘要: China has the sixth-largest bee fauna with over 1,300 documented species. Yet countless more are expected, making taxonomic work an imperative. Here, we outline the history of bee taxonomy in China and discuss how best we can move into the future and describe all of the many undescribed species remaining. Key challenges include the difficulty of accurately assigning species names due to overseas type material as well as a general need for increased internationalization such as in specimen and data sharing. Only with sustained funding for basic taxonomy will it be possible to know and protect China's unique bee fauna.

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.
