The name
Wufengalla is after the Wufeng Hill in Chengjiang. Wufeng is a Chinese word for "dancing/flying phoenix." The species name was given to honour Stefan Bengtson, a palaeontologist at the Swedish Museum of Natural History. The specimen (CJHMD00041) is maintained at the Nature Museum of Yunnan.

Another feature is body segmentation. The arrangement of the sclerites and the bristles indicate that the body is transversely segmented as in modern
