Breaking the Afrotropical boundary: Discovery of Planochelas in Asia reveals transcontinental distribution, with a new bark-dwelling species from China (Araneae, Trachelidae)

During exploratory surveys in Jiangxi, specimens of the trachelid spider genus Planochelas — previously known only from Africa — were collected, representing its first record in Asia. This finding disproves the genus’ assumed endemic status and underscores the value of surveying overlooked microhabitats for biogeographic discovery.The spider genus Planochelas Lyle & Haddad, 2009 is reported for the first time outside the Afrotropical Region, based on material collected in Ji’an City, Jiangxi Province, south-eastern China.

A new species, Planochelas jingda Liu, sp. nov., is described and illustrated. Specimens were collected from beneath the bark of Platanus spp. (e.g. P. acerifolia, P. occidentalis and P. orientalis), confirming the arboreal and cryptic habits of the genus.
