摘　　要：袁金良等(2014)发表的《论寒武系馒头组三叶虫群星虫属(Asteromajia)》一文中,将我国以往所描述的4个属(Kochaspis Resser,1935,Asteromajia Nan and Chang,1982,Hsuchuangia Lu and Zhu in Qiu et al.,1983,Bagongshania Lin in Qiu et al.,1983)及对应的15个种,归并为1属7种:Asteromajia hsuchuangensis(Lu in Lu and Dong,1952),A.quadrata(Resser and Endo,1937),A.liuheensis(An,1966),A.huainanensis(Lin in Qiu et al.,1983),A.luliangshanensis(Zhang and Wang,1985),A.?yangchengensis(Zhang and Wang,1985),A.?longiceps(Lu and Zhu,2001)。文中作者通过对原4属15种的属征和模式种特征进行相互对比研究,重新归并为2属6种:Asteromajia duplicata Nan and Chang,1982,Asteromajia hsuchuangensis(Lu,1952),Bagongshania huainanensis Lin,1983,B.quadrata(Resser and Endo,1937),B.luliangshanensis(Zhang and Wang,1985),B.longiceps(Lu and Zhu,2001)。In the present paper, through the comparison of the diagnostics among Asteromajia Nan and Chang, 1982, Hsuchuangia Lu and Zhu in Qiu et al. , 1983, and Bagongshania Lin in Qiu et al. , 1983, and some species referred to Kochaspis Resser and Endo, 1935 respectively, the author came to the following conclusions. 1） The author approves that Hsuchuangia is a junior synonym of Asteromajia, and Asteromajia duplicata Nan and Chang, 1982 and Hsuchuangia hsuchuangensis Lu and Zhu in Qiu et al. , 1983 are separate species referable to Asteromajia; 2 ） The comparison between the diagnostic features between Asteromajia Nan and Chang, 1982 and Bagongshania Lin in Qiu et al. , 1983, shows that the latter should not be lumped together as a junior synonym of the former; 3） Asteromajia quadrata （Resser and Endo, 1937）, A. huainanensis （Lin in Qiu et al. , 1983）, A. luliangshanensis （Zhang and Wang, 1985） and A. ？ longiceps （Lu and Zhu, 2001）, don＇t belong to Asteromajia and are all transferred to Bagongshania Lin in Qiu et al. , 1983 herein.
