Beautiful Scenery, Rich Bodiversity: New Springtail Species Discovered In China

Five new species of springtails from the family Entomobryidae have been described from China.

There is a Chinese saying that east or west, Guilin scenery is the best. Guilin and Chongqing, located in the western part of China, are famous for their many mountains and rivers. They also harbor unique flora and fauna, such as the scaly-sided merganser, a globally endangered species restricted to eastern Asia.

In 2023 and 2024, Dr. Yitong Ma from Nantong University, China, collected springtail specimens from the Huaping Nature Reserve in Guilin and the Yintiaoling Nature Reserve in Chongqing.

Springtails are the most common arthropods living in the soil – you can find them in your yard, in the flowerpot, or on the lawn,
he says.

“Although they are very small, usually 2-3 mm in length, their density can be amazing. As decomposers, they can break down the organic matter and promote material cycling, so they play an important key role in soil ecosystems.”

After checking the specimens from the two reserves under microscopes, Dr. Ma and his colleague from Nantong University, Xiaowei Qian, found rich biodiversity and about 80 different species of springtails. In a study published in the open-access journal ZooKeys, they described five new scaled species belonging to three genera of the springtail family Entomobryidae.

The genus Lepidodens contains five species, all found in China. The researchers find one new species, which is also the first species of the genus from the western part of China.

They also report the first sighting in China of the genus Lepidosira, which thrives best in Oceania. In Huaping Nature Reserve and Yintiaoling Nature Reserve, they found three new species of the genus.

Among the fifty species of the genus Willowsia in the world, about 30 species have been reported from China. However, the authors concluded this genus is not well represented in the two reserves, and only found one new species in Chongqing.

In the future, the researchers will further study those specimens collected from the two reserves.

Given the subtropical monsoon climate, mountainous topography and little human disturbance of the reserves, it is likely that more new species will be found,
they say.

First ever discovery of Lepidosira springtails in China reveals four new species

The tiny arthropods were found in Yintiaoling National Nature Reserve, a biodiversity hotspot.

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.

Underground gourmet: Selected terrestrial cave invertebrates and their meal preferences

Doubting whether terrestrial cave invertebrates feed on just anything they can find in the harsh food-wise environment underground, Dr. Jaroslav Smrz, fromCharles University, Vinicna, and his international team conducted a research in Slovakian and Romania caves. They tested the hypothesis that these species have rather negligible selection of food. Their microanatomical research into the gut content of several microwhip scorpions, oribatid mites, millipedes, springtails and crustaceans showed, however, that there is an evident meal preference among the species.

The results confirmed that the studied groups can adapt and develop under the pressure of extreme environmental factors. Therefore, the researchers concluded a low level of food competition. The study is available in the Subterranean Biology open-access journal.

The scientists studied the cells and tissues of the selected invertebrates and found out that the gut contents were nearly identical between the representatives of each group. This was the case even when the specimens had been collected from various locations. For instance, all microwhip scorpions proved a preference for cyanobacteria, while the mites favored the bacteria found in bat guano and the millipedes – fungi.

“The limited food offer seems to be used very unambiguously and thoroughly by the invertebrate communities,” the research team explained. “Therefore, the competition for food can be actually regarded as very low,” they concluded.
