Abstract:

Aims: This study aims to provide a systematic review of new Diptera taxa described from China in 2024. 

Methods: By searching databases and relevant taxonomic journals, 51 journal publications on new taxonomic groups of Diptera from China in 2024 were systematically collected and analyzed. 

Results: In 2024, a total of 107 new taxa were identified, including 1 new genus, 106 new species, 2 new recorded genera, 18 new recorded species, and 2 synonyms. These new taxonomic units belong to 23 families. Empididae exhibited the highest number of new species descriptions (28 species), representing 26.4% of the total new species and significantly exceeding the contributions of other families. New taxa and records were distributed from 24 provincial-level administrative regions. Yunnan Province emerged as the core area for new species discovery, with 35 new species recorded, constituting about one-third of all new species described. The 51 relevant research papers were mainly published in three journals: Zootaxa, ZooKeys, and Entomotaxonomia. 

Conclusion: In 2024, the total number of papers and the number of involved journals showed a downward trend, reaching the lowest level in the past five years. The locations where new species were discovered remained concentrated in hotspots. Many Diptera species in different regions and ecosystems have not been thoroughly explored and described, and more attention is needed in the future.
