Researchers from Nantong University have announced the discovery of four new species belonging to the springtail genus Lepidosira in China, representing the first record of this genus in the country.
The findings, confirmed by both advanced molecular and traditional morphological analysis, are published in the latest issue of Museum für Naturkunde Berlin’s open-access entomology journal Deutsche Entomologische Zeitschrift.
Led by researchers Xiaowei Qian, Meidong Jing, and Yitong Ma, the study involved extensive fieldwork in the Yintiaoling National Nature Reserve in Chongqing, a biodiversity hotspot in southwestern China.
Through COI barcoding and meticulous examination of physical characteristics, the team identified and described four species new to science: Lepidosira apigmenta, L. similis, L. wuxiensis, and L. chongqingensis. These species expand scientific understanding of the diversity and evolution of springtails: tiny, soil-dwelling arthropods that play a critical role in ecosystem health and soil fertility.
In addition to introducing these new species, the study proposes taxonomic updates, including the transfer and renaming of two previously known Chinese species based on their true affinities to Lepidosira. The use of genetic barcoding was key to overcoming the limitations of identification methods based only on colouration, a common but unreliable trait in traditional Collembola taxonomy.
The research team also provides an updated identification key for the scaled genera of the subfamily Entomobryinae, further facilitating future studies in the region.
This discovery highlights the richness of endemic species in China and the importance of continued exploration in under-studied habitats. The work was supported by the National Natural Science Foundation of China and the Large Instruments Open Foundation of Nantong University.
