摘要

A new clausiliid species Formosana jianyueae n. sp.[ 见玥管螺], collected from the Manghe Macaque National Nature Reserve, Shanxi Province, China, is described and illustrated. This is the first species of Formosana described from Northern China; it is a medium-sized, dextral species characterised by the combination of a lamella superior indistinctly separated from the lamella spiralis, receding lamella subcolumellaris, lateral to dorsally ending plica principalis, and four or five strong palatal plicae. This new species represents the first clausiliid record from Shanxi Province and the northernmost natural distribution of Formosana species in China.
