## Contribution

Three new species of Atypus spiders are described, along with expanded knowledge of their natural history.

## Key findings

- Three new Atypus species were identified and documented from southern China.
- Natural history observations of Atypus spiders were compiled over a decade of field and lab work.
- Descriptions include detailed morphology, color photos, DNA barcodes, and a distribution map.

## Abstract

Purse-web spiders are fascinating creatures that build unique silk tubes for hunting and protection. They remain relatively unknown among non-professionals, primarily due to their living in distinctive yet inconspicuous webs. One end of each web remains underground, while the other end extends above the surface and maintains a nearly vertical orientation to the ground, blending seamlessly into the surrounding environment by attaching to plant stems or other nearby surfaces. Our understanding of the natural history of purse-web spiders was previously limited due to their underground habitat. However, through a decade of observation conducted both in the field and in the laboratory, we have significantly enriched our knowledge of their behaviors and habits, which we report in this study. Additionally, we describe three newly discovered purse-web spider species within the genus Atypus, collected from Hunan and Sichuan Provinces in China. We provide detailed descriptions, color photographs and DNA barcodes of all new species, and a distribution map of Atypus species in China.

Three species of the purse-web spider genus Atypus Latreille, 1804, collected from Hunan and Sichuan Provinces of China, are diagnosed and described as new to science: A. yaozu sp. nov. (♂♀), A. siyiensis sp. nov. (♂♀) and A. yanjingensis sp. nov. (♂♀). Detailed descriptions, photographs and DNA barcodes of the three new species and a distribution map of Atypus species in China are provided. Additionally, we enrich the general natural history of the genus Atypus through a decade of observation.
