The genus Ibana Benjamin, 2014 was established, based on the type species Ibana senagang Benjamin, 2014 from Borneo, Malaysia. No species of this genus has been recorded from China. A new species of Ibana is described and illustrated, representing the first record of the genus for China. Ibana gan sp. n. differs from its congener by the yellowishbrown longitudinal band on the abdomen and the round, contiguous spermathecae. The distribution of the new species in Jiangxi Province is mapped.

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.

Collections of thomisid spiders by amateur and professional arachnologists in China have led to the discovery of some interesting crab spiders (Thomisidae). Two new species in two genera of thomisid spiders are described and illustrated with photographs and SEMs: Pharta xizang Liu & Yao, sp. nov. (♀) and Stephanopis qiong Liu & Yao, sp. nov. (♀). The previously unknown males of Borboropactus longidens Tang & Li, 2010 and Stephanopis xiangzhouica Liu, 2022 were also collected and are described for the first time. The genus Borboropactus Simon, 1884 is reported for the first time from Vietnam. The new Stephanopis species is also recorded for only the second time from the Asian mainland. Distributions of all these species are mapped.
