Five specimens collected from the Guole For- mation of the Furongian (Late Cambrian) in the Guole area of Jingxi, Guangxi, are described. One new species Nanocarpus guoleensis sp. nov. is proposed to accommodate these new materials. The new species is defined by the small-sized, long pear-shaped theca which sharpens backwards. The frame, consisting of ten broad marginal plates and two short adoral plates, has an integral front part and an unclosed back part. The zygal is sturdy, with an obvious breach between the front and back. The anal pyramid is located on the extremity of theca. The aulacophore is relatively shorter and has a relatively wider base, carries some fine spines at proximal part and rough thorn on distal part.
