文中通过对我国己发表的palaeolenid类三叶虫中的34个种头盖特征组合进行Q型聚类分析,研究我国palaeolenid类三叶虫属种的分类,并结合传统定性分析,对该34个种(包括2个属、1个亚属和1个亚种)进行修订,且合并成1个属4个种(亚种),即:Palaeolenus douvillei Mansuy,1912,Palaeolenus lantenoisi Mansuy,1912,Palaeolenus lantenoisi longispinus(Chang and Chu,1980)和Palaeolenus fengyangensis Chu,1962。文中还提出沧浪铺组乌龙箐段可采用Palaeolenus fengyangensis带(上)和Palaeolenus lantenoisi带(下)两生物带意见。
In this paper, the Q-type cluster analysis of the 34 head cover combinations in the published Paleoeolenid trilobites was carried out to study the taxonomic classification of the Paleoeolenid trilobite in China. Combined with the traditional qualitative analysis, the 34 (Including 2 genera, 1 subgenus and 1 subspecies) were revised and merged into 1 genus 4 species (Palaeolenus douvillei Mansuy, 1912, Palaeolenus lantenoisi Mansuy, 1912, Palaeolenus lantenoisi Longispinus (Chang and Chu, 1980) and Palaeolenus fengyangensis Chu, 1962. It is also suggested that the Palaeolenus fengyangensis belts (upper) and Palaeolenus lantenoisi belts (lower) belts may be used for suggestion in Wulong Bay of Canglangpu Formation.
