| Abstract: | New polymerid trilobites are described from the middle part of the Huaqiao Formation in Fenghuang area,western Hunan, an area known as one of the most richly fossiliferous areas in China for Middle and Late Cambrian trilobite faunas. The trilobite faunas of this area were recorded previously by some authors. The new material was collected during recent investigations on the trilobite biostratigraphy of Middle and Upper Cambrian of the area. Three new and a single open nomenclature species are described here, all from the Dama section in Fenghuang County. They include Hardyoides damaensis sp. nov., Meringaspisdamaensis sp. nov., Rhyssometopus (Rostrifinis) nitidus sp. nov. and Erixanium cf. Erixanium sentum Opik, 1963. This is the first record of Erixanium from eastern Guizhou and western Hunan. The significance of the new taxa in biostratigraphical correlation of Cambrian within the Australo-Asia Province is discussed. |
