| Abstract: | Based on new material from the Middle and Upper Cambrian (Huaqiao Formation and Chefu Formation) of eastern Guizhou, South China, the genus Prodamesella is here revised and subdivided into three subgenera: Prodamesella (Prodamesella) Chang 1957, Prodamesella (Metaprodamesella) subgen. nov., Prodamesella (Neoprodamesella) subgen. nov. According to cranidial and pygidial features, Prodamesella is here transferred from Damesellidae to Missisiquoiidae; tentative phylogeny of Missisiquoiidae is briefly discussed. |
