Lysiteles Simon, 1895 is one of the largest taxa with small body size among the Thomisidae and is mainly distributed in East, South and Southeast Asia. Most of them are recorded from southern provinces of China, such as Jiangxi Province, including three species. However, all of them are only discovered from Jinggang Mountain National Nature Reserve in Jiangxi Province. But there are still other species remaining unknown which need to be surveyed from other areas in this Province.
One Lysiteles species was collected from Nanfengmian National Nature Reserve in Jiangxi Province. Based on morphological characters, it was recognised as a new species and has been named as Lysiteles nanfengmian sp. n. It is described and illustrated with photographs and its distribution is also mapped.

The species of the genus Lysiteles Simon, 1895 usually live in shrubs, grasses, tree foliage and leaf litter, sometimes in canopy (
The genus has a relatively wide distribution in East, South and Southeast Asia, with thehighest number species in China (44), Bhutan (ten) and Nepal (eight) (
From 2015 to 2022, many spider taxa have been discovered by our team in south-central Jiangxi Province, such as Agelenidae (
Jiangxi Nanfengmian National Nature Reserve is located in the south-central section of Luoxiao Mountains and on the common boundary of Jiangxi and Hunan Provinces, which ha a subtropical monsoon climate. While studying thomisid spiders from there, one undescribed and poorly known species was found. The aim of the present paper is to provide a detailed description of this new species.
Specimens were examined using a SZ6100 stereomicroscope. Both male and female copulatory organs were dissected and examined in 80% ethanol using an Olympus CX43 compound microscope with a KUY NICE CCD camera. Epigynes were cleared with pancreatin solution (
The measurements were taken using a stereomicroscope (AxioVision SE64 Rel. 4.8.3) and are given in millimetres. The body lengths of all specimens exclude the chelicerae and spinnerets. Terminology of the male and female genitalia follows
Leg measurements are given as total length (femur, patella, tibia, metatarsus, tarsus). The abbreviations used in the figures and text are as follows: ALE − anterior lateral eye, AME − anterior median eye, At − atrium, CD − copulatory ducts, CO − copulatory openings, d − dorsal, Em − embolus, Fe − femur, MOA − median ocular area, p − prolateral, Pa − patella, PLE − posterior lateral eye, PME − posterior median eye, r − retrolateral, RTA − retrolateral tibial apophysis, Se − septum, Spe − spermathecae, Ti − tibia, TR − Tegular ridge, v − ventral, VTA − ventral tibial apophysis.

The male of this new species is similar to that of Lysiteles torsivus Zhang, Zhu & Tso, 2006 (
The specific name refers to the type locality; noun in apposition.
When we collected all illustrated descriptions of the Lysiteles species, one of the interesting findings is that some of them can be assigned in one sub-group by the embolus with a spiral or strongly curved tip and the large RTA longer than the tibia and the female epigyne with the distinct septum dividing the atrium into two large parts, including L. arcuatus Tang, Yin, Peng, Ubick & Griswold, 2008, L. auriculatus, L. corrugus Tang, Yin, Peng, Ubick & Griswold, 2008, L. dentatus Tang, Yin, Peng, Ubick & Griswold, 2007, L. dianicus Song & Zhao, 1994, L. qiuae Song & Wang, 1991, L. silvanus Ono, 1980, L. spirellus, L. subdianicus Tang, Yin, Peng, Ubick & Griswold, 2008, L. subspirellus and L. torsivus (
