记述了采自鄂西地区早志留世Llandovery (Aeronian)的三叶虫Aulacopleura (Aulacopleura)wulongen sisWang的个体发育。运用分支分析研究了深沟肋虫亚科 (Aulacopleurinae)各种的最佳聚类 ,确定该亚科目前仅含Aulacopleura一属 ,Songkanina属是Aulacopleura (Paraulacopleura)亚属的同物异名。Aulacopleura一属的祖先种为A .szechuanica ,在系统演化中存在幼型形成和过型形成两种异时发育现象 ,Aulacopleura (Paraulacopleura)各种为该祖先种的幼型形成后裔 ,而Aulacopleura (Aulacopleura)各种为它的过型形成后裔。
The individual development of the Trilobite Aulacopleura (Aulacopleura) wulongen sisWang collected from Early Orange reserve Llandovery (Aeronian) in western Hubei Province is described. Using branch analysis, we studied the best clustering of Aulacopleurinae, and identified the genus Aulacopleura, which belongs to genus Aulacopleura and genus Songkanina, which belong to the genus Aulacopleura (Paraulacopleura). Aulacopleura, an ancestor of A.curastris, is a member of A.szechuanica. There are two types of heterochronosis in the phylogenetic evolution. Aulacopleura (Paraulacopleura) forms a descendant of the ancestral species, whereas Aulacopleura (Aulacopleura ) A variety of descendants form its over.
