Abstract
BACKGROUND: The genus Chinattus Logunov, 1999, a group of jumping spiders (Salticidae), has been recorded across multiple regions in China. Current records indicate its presence in Anhui, Hunan, Yunnan, Hubei, Taiwan, Guangdong, Hong Kong, Guizhou, Fujian, Chongqing and Sichuan Provinces. These reports highlight a fragmented, but widespread distribution in southern and central China, particularly in mountainous or subtropical habitats. Notably, Jiangxi Province, situated adjacent to several documented regions (e.g. Hunan, Fujian), lacks any confirmed records of Chinattus to date. This absence raises questions about potential sampling gaps, ecological barriers or environmental factors limiting its presence in Jiangxi, warranting further investigation to clarify the genus' full geographic range and habitat preferences within China. NEW INFORMATION: A new species Chinattushuanggangshan K. K. Liu, sp. nov. is reported from Jiangxi Administration Bureau in Wuyi Mountain National Park, Jiangxi Province. Detailed morphological descriptions, photographs and the distribution map of this species are provided.
